I have been trying a wide variety of powders and loads over the past couple years, to see which gave me the best accuracy with my Accurate Moulds 312112M plain base, cast bullet. Note: if you order this mould, crimping in the groove means that you will be levering the bullet into the lands, which puts too much strain on the levering mechanism for my money. I use a Lee Factory Crimp and set the bullet in just enough to not quite touch the lands, and crimp it there on the forward driving band. Powders ranged from Unique on the fast end to IMR 4198 on the slow end. Finally, I laid all the targets out on my pool table and made my selection ... 9.5 grains of 5744 with a small pistol primer, for a velocity of 1,230 fps and an E.S. of around 17 fps in 10 shots. This is out of my original Model 53 32 W.C.F. made in 1929. At 25 yards, a 3-shot group is about 3/8" (which is the average range I deal with varmints). At 50 yards, a 5-shot group is roughly 1", and at 100 yards, the 5-shot groups are around 2 & 5/8".

Kirk, sure sounds like you have been having some fun with the load work for that beauty. I did end up with a couple of real good 5744 loads for my old 92 32wcf. Thanks for all the help with that project. That should take care of some of those big groundhogs your alfalfa field.

Thanks, men. JerryB, I forgot what load you settled on for your 92. M. M. Wright, I'll be interested to hear how it does in your rifle.

I never pay much attention to crimping grooves on cast lead bullets. If the OAL works out to use them, that's fine. But if not, I'm more concerned about function and accuracy, so crimp mine wherever it works best. Looks like you found where it works best!
Thanks, GunnyMack. I was very fortunate to come across this one in a gun store that had just bought it from an elderly gent and wanted to move it.

Kirk, I had several loads with 5744 that gave good accuracy. The load I really like for my old rifle (1917)is a 100 grain XTP over 11 grains of 5744. I am hoping to take a deer with that load, maybe this year.

11 grains should move that XTP bullet along at a good enough clip to put a deer in the freezer.

Thanks much for posting the results of your accuracy trials, Kirk. Your load is real close to my "grandkid preferred" load that I build using Red Dot and the Ranch Dog 117 grain bullet used without the gas check. But you are getting much better velocity consistency than I get. Verrrry interesting!

KirkD......(or others)...
Do you find any shorter brass life using the Lee FCD on the notoriously thin-walked 32-20 cases than when you use other types of crimp...?
I crimp the brass onto the forward driving band of the cast bullet, so there is much less reduction in brass neck diameter than when it is crimped into a crimping groove. I expect the brass should last longer this way.
