Been wanting a brush gun for deer and wild dogs, something for under 100 yards. I began this a couple of seasons ago before the 450 bushmaster came out, I would just go with that now but I am too far along. I am thinking this will do nicely for what I want.

Kinda a mix and match gun still in progress. The barrel is a spare thomson I had laying around. The front sub is a type III with full length rebuild plates, a romy rear trunnion and triggerguard. The stock, PG and foregrip will all be baltic birch, the gas block, gas tube, flash suppresor and magazine are all made by me.


For those of you not familiar with the 45wm,
Heres a comparison of 9MM, 45 win mag and 762x39



Here is a round chambering.




Here's the hollow points I am planning to use, 230 grains at approx 1700fps should be reasonable.


And here is the work in progress, I will use a ring around the front sight post on the GB for the front and a ar15 A2 aperture for the rear sight, mounted on the rear of the top cover. I will smooth the stock and front grip when I get closer to being ready to shoot. Pretty much all that is left is to ream the chamber, silver solder the GB on and drill the gas port.

That's a hell of a project! Looks good so far, especially in 45 Win Mag. Amazing round! I buy the cases & trim & ream them for use in my 45 SUPER. Looking forward to the finished pics & range report.

It will be gas operated. The pressure is way too high for a blow back. The gas block is a piece of 4130 tube for the barrel portion, a piece of 4130 .248" thick as a spacer and then a piston cup with a gas tube press fit into it and an outer sleeve over top for smooth appearance. All welded togther and then smoothed down to what you see. I will cut gas vents when I get an idea of where they need to go. You can see the slots in the GB for the holes to be drilled later.
The bolt was just chucked up and turned a little larger on the face and the extractor stoned to fit the new diameter of the brass.

Seems most of the photo bucket photos are gone. The mag was for 5 rounds so I could hunt with it. Never got the feed 100%. Typically the mag spring couldn't get the next round up in time for feeding on 2nd and 5th round.

Wow. Sorry I havent been here in a while. The mag is 1x2 steel box. The angles are all copied from a grease gun mag but made longer for the longer case lengths. The spring IIRC was from a g3 mag.

My biggest tip is polish, polish, polish the interior feed lips. Make them like butter.
