Canadian Airgun Forum

Hey guys, hope all of you are well, like most of us I've been bored with this social distancing so figured i'd share the precharged pistol I had built a while back. tube is shortened disco, 22xx gripframe, barrel I made and rifled but is salvaged from my caselman project, front sight is fabbed, breech is one I cast from aluminum. I am in the process of building wood grips now. .375 is a pretty heavy payload for this pistol and the 80 grn. lead ball I get around 4 shots plus a weaker last starting in the 460, 465, 469, 479, and 380. the slugs are from a lee mold I milled down to lighten from 130grn to 104, havent chrony'd the slugs yet but suspect they will be a bit slower, hoping they will seal in the barrel like my greysquirrel gun, that seems to like them. Stay safe all.


cheers-Matt

Very nice, would you show us more on the diy casting of the breech

Yep! That's a very nice one!!
The speed is consistent, how about the accuracy? Can't find lighter slugs at this caliber to maintain a better balance to improve accuracy than the lead balls??

@ pistolero, I cast the breech using a steel form, basically a pipe with a notch cut out the length of the bottom, then a reversed section inlaid and spot welded to give shape to sit on maintube, then i used steel bushings at the ends, a steel rod run down the center, then left a small spot to tack weld a steel pipe as a funnel to pour molten aluminum into the whole thing. It's a sketchy dangerous way but unless you have machining equipment.......the rod doesn't like to come out so i had a "T" handle on the end and once poured i wriggled the rod to get clearance then had to put back in the forge to get aluminum soft again, I learned the hard way to let it all cool slowly and the aluminum shrinks back a tiny bit giving a lil clearance to help remove the rod. first attempt i quenched when hot only to find the aluminum shrunk back too fast and cracked in half.

YepYep, I've tried to build a actual pellet mold, didnt work out, all i could find was the lead ball and slug mold, originally the ball were for the caselman i built and ball was easier to feed in a tube mag, still may mod the slugs some more but if someone could build me a pellet mold that would be fantastic!

That sucker could do some damage.
How much fpe does it put out? What, 40 ftlb - you'll put your eye out!

Very interesting indeed. I thought everyone had at least one .375RB mould.
I do, but cannot remember why.

Woah, this is awesome!

Did you have to modify it to let out more gas? If so, how? I'm not well versed in how c02 pistols work.
