577 T-Rex built on the GMA action with modified magazine box to hold two down in a vertical stack configuration, and snapping over a chambered round for three total. Bench-made quarter rib, front sight, and sling studs. The safety is from a 1909 Argentine. Weight is a lively 12 lbs.

Looks Great Wayne! Does it come with a mouth guard?

Nice looking but you could run woodsmoke through that stovepipe!

That'll keep a chiropractor busy :-)

That rearsight was vertical before the first shot was fired.

Very nice rifle!

And you lot stop making fun of it.

Any decent rifleman could handle it.

It I do prefer the “non decent” ones!

Saeed, they're just a bunch of sissies suffering from bore envy. Probably drink Bud Light too.

Gastroenterologists like their butt light. Sorry. Could not resist.
P.S. Nice thumper ya built there Wayne.

Make sure you don’t load it too hot or the safety will set back
Very nice job though!

I like it!

How long is the barrel?

20 inches

A saddle carbine!

45 grains of UNIQUE and some Kapok with a 750 grain bullet is a great practice load.

It's regulated with 150 grains of H-4350 and a 750 grain bullet for about 2,150 fps. It will be off on a trip for Buff soon.

It's pronouns are He/Him

You are lucky to have a fast barrel.

Ours gets 2001 with 160 grains of the same powder!

You are correct. I read my notes wrong. The velocity was 2,050 give or take.

Still lots of difference.

10 grains more for my data??

Hmmm, could be my cases. My brass has thicker walls and less capacity than the original A-Square or Horneber. My max loading is 175 grains of H-4350 with with a heavy compression. I know the other makers' brass holds quite a bit more. At 150 grains the case is 100% full with a banded solid. Maybe the less case capacity and resulting higher pressure makes the difference. Also the banded solids usually go a little faster.

In our test we used original A-Square brass, which I am not too impressed with.

Very well proportioned beast!!!

I forgot to add nice pics Wayne

Beautiful thumper! WOW!

Beautiful rifle, Wayne!

That’s an absolutely gorgeous rifle!!! Not sure I’d like shooting that gun with full power loads but simply handling it would be awesome.
