Yes, cast .507 750gr for a belt fed ma deuce, way overpowered. It failed.
just got back from a three day camp trip and decided to see how much those "325 grain" bullets really weigh. in grains: 324.1, 320.6, 320.0, 321.3, 321.3, 319.9, 322.5, 321.9, 322.3, 321.9. all bullets measured 4.525" +/- .0005" in diameter.
so this bullet is really a 320 grain bullet. the avg. for these ten is 321.6, the extreme spread is 4.2. i see i am going to have to weigh the bullets if i want them all to be within a couple of grains of each other as that 324 grain bullet is way off.
so, walkalong, what do your bullets really weigh?

YepIt's a cast lead bullet, plain and simple. Plenty of very hard cast bullets on the market. The ones I shot in the old Blackhawk years ago were harder. Too hard, harder than needed even for the .454.
Alright @JShirley , we'll be waiting on a range report! Is the intended target paper, steel or critter?350 pumpkin chunkers all ready to go.

Well, I'm moving to NC. In NC, literally any caliber is legal for deer. I'd like a load that's safe for my Model 25, that will blow right through a deer at moderate ranges.Alright @JShirley , we'll be waiting on a range report! Is the intended target paper, steel or critter?
Absolutely. I know we originally were thinking of driving them 50% faster, but I have so much .454 and hot .45 that there's just no point.So, after use...
Think you're satisfied with the projectiles?
Switching to the heavy cast felt different. The recoil wasn't heavy or punishing, but was more noticeable.

Beautiful state NC. Spent quite a bit of time over the years riding Motorcycle in the Maggie Valley/Robbinsville/Nantahala National Forest areas. Intend to make it back again, hopefully. You got a good projectile, running at the velocity you want and will safely shoot in the 25. Hopefully you can do something about the high POI. If she's shooting 4" high at 18 yards, she's probably what, 7-8 inches high at 30?
John and I sighted that in together (Steel plate was a little over 50 yards), and the recoil is substantial, plus it has way more power than is needed to kill deer.BFR Casull, which is so unpleasant to shoot with true full power loads
