Boomer Moulds
Just received, cast, loaded and shot my first bullets from a Boomer mold. I ordered a 40cal mold made to my spec's and the bullets cast with 20-1 alloy are within 0.0005" per my digital vernier. Can't complain about that.
I ask for length that would result in 330-340gr for shooting chickens. Leo Bumphrey, Boomer's owner, suggest a 3-groove bullet with 3-GGs. The bullet casts at 334.5gr for me at 775F.
The 2nd best part is it is a very easy mold to cast with. Out of my initial 50 bullets cast only 3 of them had to be tapped out of the mold after opening. That's as good as my best nose-pour mold.
But, the very best part is at 200yd it is a 1-moa bullet when shot from my 40-65. Very pleased with the 'on-paper' results. Now have a good 'chicken bullet' with minimum recoil. Now I just have to do my part (the big 'X' in the chicken equation).

Boomer 410 grain Money bullet shot in my .40-65 Shiloh Sharps.
First shot outside cluster but she shoots 1 MOA once the barrel is fouled.

Re: Boomer Moulds

Yes. After a health related layoff he is back at it. Received mine about two weeks ago.

My Boomer 40cal 335gr elliptical nose 'chicken bullet'. Will see how it does in the 200yd string at our Oct 9 BPTR mid-range match.

Re: Boomer Moulds
Don't know about the 50cal bullets, but the bands on my 40cal bullet measure 0.409" on all three bands, as ordered.
