To continue the PM5 saga, I am happy to report that I now have it working reliably in its 4th version.
I have dispensed with the rear mag release, this was causing all sorts of problems as it moves in the same plane as the recoil and inertia of firing. I used the mag release housing to mount the new rear wall of the magwell. This is keyhole fitted in place and retained by the original mag release pivot drift pin. (This is in keeping with my stated intention of being able to return the gun to stock configuration if ever need be) The forward end of the magwell is one piece , comprising the locating lug, feed ramp, magazine stop and retaining pin hole. This is carved from a 1" aluminium billet and imparts strength to the whole magwell. It is a little bit "Tonka" but better too strong than too weak. Using this "one piece" construction has enabled me to eliminate the unsightly side plates of the earlier versions) The right hand side is 5mm aluminium plate for strength and rigidity. The left hand side is a laminate of 2mm and 3mm sheet to facilitate the entry of the magazine with its new side block. This block is brass, 25x10x3mm and is located on the magazines via one of the original peep holes with a countersunk hex screw, a touch of 2 part epoxy prevents rotation. The Magazine release catch on the left side is an spring loaded oversize 1" (25mm) lever which connects to a block which protrudes into the well 3mm. this gives a contact area of 75 sq mm with the magazine so retention is 100%. The magazines are now held securely, and, more importantly, consistently in the right place for accurate feeding and reliability. I have added to the mag followers a small plastic ramp which also assists with getting the right approach angle to the chamber. Another modification is the "Cactus Arms" mag extension. I found that my original extensions were a little on the flimsy side (not best suitable in the knockabout world of combat/practical shotgun!) and in fact I had a few magazine spring assisted fall-aparts which were embarrassing to say the least! The "Cactus Arms" unit is a solidly made ABS extension for the Saiga/Bora shotguns and was modified with a small aluminium plate to compensate for my slightly narrower magazines.
To close, I have yet to finally cosmetically finish and paint the magwell but with more testing and use to come I shall leave that until later. I may try and incorporate an ambidextrous release but will need to think long and hard about how to achieve that whilst keeping reliability. For now, I'm enjoying the fruits of my labours, but no doubt more tinkering will be done in the future, I love a challenge!

Ever see the sci-fi TV series, "Firefly"? Your gun reminds me of the weapons in that series. (You don't call your PM5, "Vera", do you?)

It looks like you're havin' a shed-load of fun with that gun.

Regards,

Mark.

Its been a mission that's for sure, my original plan was to have a box fed pump which would then trump the box fed auto boys when they got all ammo sensitive which they have a wont to do. Now the PM5 is not at all ammo shy, it will digest anything including reloads. Getting the mag loading right though was a lesson in measure twice cut once, although I should preface that with think four times first!
All I need now is a competition where ammunition becomes an issue and I can clean up!!
Seriously though, I still rate the PM5 for its simplicity, it was not designed as a competition gun, rather like the M37 and in the old days my beloved Colt Python. Nevertheless, its now able to perform as I wish and the only shaky part is the nut on the butt!
Rather like yourself I tend not to go the obvious way to my shooting but I enjoy it immensely, long may us quacks continue! Been looking at a martini action Greener GP, I should not have watched that rerun of Zulu............Front rank fire! Rear rank fire! Third rank fire! Team clay shooting with 3 birds flying anyone?

PS the PM5 and my Sabattii 1822 have been named The Fuglies by The Pigeon watch forum and the Frankenstein sisters by my club peers

PM5 cont...........A few practice sessions have confirmed the reliability and ruggedness of the magazine well and system(happily!) Unfortunately, the 552 sight that I was also testing fell off due to a poor fixing of the picatinny rail (now remedied) but I digress, the large 'slap' release button is easily reached and the mags drop out smoothly. I felt though, that a little finesse would assist when carefully aimed shots or restricted space dictated a slightly different approach. I reasoned that an ambidextrous release was not really feasible if I wanted to retain the simple, reliable mechanism. What I came up with is a simple lever attached to the top of the existing catch, (if it ain't broke don't fix it) which I can simply push up with my trigger finger to drop the magazine. I figured that for the amount of times that I would be shooting left-handed, I could live with the original catch.
Anyway, I will test it out this weekend and hope to report back in the positive

To continue, I am happy to report that all is well with the PM5 magazine system. From loading the magazines to inserting, feeding, ejecting and unloading, all functions are simple effective and reliable.
So begins the next phase, a sighting system that suits me. As I am right-handed but left eye dominant (some would call cack-handed!) I needed to find a way to fast target acquisition, accuracy on the move and again simple reliability. I use on my .22 an offset red dot that works for me so I have tried to duplicate that with sights and hardware that I have available and that I know are suitably shock-resistant. Also, as there is weak hand shooting in my chosen sport (where my left eye dominance is actually a help) I needed a bore line sight also. I already have the bore-line laser fitted under the barrel for close-in instinctive shots (it also is effective in smoky or dusty courses of fire where the visible beam makes target location easier)
What I have come up with, and will field test soon is the following; A relatively crude but simple and effective binocular sight system consisting of an offset green dot for my left eye and a bore-line red dot for my right eye. With the natural cant of my head when in the aim, I can see both dots. They converge at about 12 yards to a single point, together with the laser. Most of our steel plate targets are at between 10 and 15 yards so aiming is really easy with both eyes open and full peripheral vision. I don't know if this is innovative but I have not seen anything similar(maybe the forum members know of something similar?) I have attempted to demonstrate with the accompanying photos on a sheet of paper at 6 feet, which basically from my point of view at that close range gives an upside-down triangle, green dot top left, red dot top right and laser centre bottom. For left handed shooting , the green dot is redundant. Everything is known shock-proof and solidly mounted, just maybe looks a bit weird!

I just had a quick look at our calendar and it says that the next Open is on Sunday, April 30th.

Now, *usually*, the Crew Shoot is two weeks before. However, *this* time, it's on 2nd April. I don't know why. I mention the Crew Shoot because we usually have one or two places available for non-crew competitors who can't make the main shoot.

As I learned last year I need to get in early

Yeah, it's a bit popular. The site looks pretty much like this when the bluebells are out:

Oh, well done!

Unless sommat crops up, I should be crewing. (If it's nice, my cap'll say "ChAoS"; if it not, I'll probably have a wide-brimmed hat on of some sort.)

A Brief update on my 'Binocular' sight experiment for the PM5.
It seems to work, up until the small (bore-line) sight gave up (battery shift, need to address that) I was finding that I could acquire and engage targets much easier and it felt very natural. I think that higher quality sights would be a vast improvement but nonetheless I am happy to move along this road. As an after-thought I had fitted, in case of a total failure, some flip up iron sights and these work fairly well too, particularly for slug.
Downside? well the gun definitely looks a bit strange. Some people like it, purists think it an abomination! Also, with the master eye sight 2" left of the bore, in some courses of fire it could contact or be obscured by the side of the barricade, if shooting left handed, but, as this is competition and not the real world I can live with that, if the briefing states 'left shoulder' I will be able to remove that sight for that course of fire

Wow! how cool is that? :D
Unfortunately, despite being a bit past my 'best before' date and a bit long in the tooth, even I wasn't around in 1915!
That rifle illustrates perfectly what I find so fascinating with firearms, namely the way they work (that one clearly external) and has reawakened a pet idea of mine which I drew up plans for (and can't now find unfortunately :()
It was to make a self loading Model 37. I never found a 37 that I would risk, they were all too precious! Now if only I could find a real wrecker.......maybe I would have a go
What slightly put me off was Remington's failed 105 CTI bottom eject autoloader, which, while a beautiful piece of engineering was not reliable and was phased out after a short production run. I thought if they can't do it, how could I? But there again, they did take the Mag 10 and ruin that!
Anyway thanks for that link, I am sure many will find it interesting.

As an aside, perhaps you would email me with directions to Popham, looking at google earth, it seems that the entrance is from a layby on the Eastbound A303?

The whole "Forgotten Weapons" channel is worth viewing.

This, I have done although my "Sent" folder seems to indicate that I had a little, um, "finger trouble" and sent two emails - one, "sans attatchment"... :)

Now re-worked with a matching pair of parallax free dot sights plus magpul type flip-up in case of total tech failure...............

rather like how many people can you get in a Mini...how many sights can you get on your rail?!!

Thought I would bring the forum up to date on some recent acquisitions in the non Ithaca area, usually bought very cheaply, privately or at auction. All are in full working order now after component level strip-down and some deep cleaning and subsequent function testing. I have been fairly fortunate in that no major parts have been required, just a few pins and springs etc.
Firstly, my first Winchester, a model 1200, 28" barrel, winchoke system, a very nice handling gun
Win 1200.JPG

A fairly early Remington 870 Wingmaster, 30" full choke. Not marine finish as it appears, I have stripped off most of the finish in preparation for a re-blue. This gun does need a trigger guard as some bright spark decided to drill lightening holes front to back for some unknown reason. Doesn't affect the gun but looks a bit stupid.

Thirdly an SKB 200E, ostensibly the same as the Ithaca 200E as made in the same place. With 26" imp and half choke barrels its a fast handler on pigeons and clays, I'm getting to grips with its clean up as it was in a fairly sorry state when I bought it. I will probably have the barrels re-blacked professionally as I think the gun deserves it. Nice, crack free wood will come to life with a total strip and Danish oil finish

Definitely! I had a 59 impala convertible which was unfortunately a basket case. They are so expensive now that I will need to win the lottery to get another! Always liked US '50's styling and Chevys in particular.
Incidentally, I am currently in the Greek Ionian islands on vacation and just across the water from where I am is the island of Ithaca, home to Odysseus and of course namesake of our favourite guns!

edit......
Just got back from Greek Islands, this souvenir seems appropriate for this site!

New Acquisition!
This is a Hug San Huglu TS 870
You would be forgiven for mis-identifying this gun, and I bought it mainly out of curiosity. It looks like, shoots like and takes down exactly like a 37. Its obviously a clone (Turkish) but I have never come across this one before. It makes the Norinco YL12 M37 clone look very poor in comparison and aside from some rough internal machining (which doesn't affect anything) its a nice shooter with some features that we in the UK don't see on our 37's yet such as 3" magnum, steel proof and screw in chokes. (Mobile I believe) I don't believe that it devalues my collection as it is well put together, shoots well and is not a bad looking gun. An oil treatment will hopefully bring out the figuring on the woodwork. It would seem to be out of production as the current Huglu pumps are all side eject. I wonder if it was such a close copy that Ithaca took some action? Any information would be welcome.

Interesting. Looks to have a longer magazine tube and post war styled checkering. I will have to do some research on this.

It’s an 8 shot model but UK restricted to 3 shot with the tube crimped . The carrier/lifter/ejector is interesting as the steel is much more springy, when in the fully down position the tips are about 1/4” apart, ejection is extremely positive. The carrier pivot screws have only one cut out for the lock screw which is about a sixth of a turn back from tight. The threads are metric all round.
