Bought 500 .32 caliber round nose moly-coated 80-grain boolits sized to .311 from Bear Creek Supply. https://www.bearcreeksupplybullets.com/32-acp-80gr.
Intend to load for a Yugoslavian Crevna Zastava 7.65mm Browning (.32ACP) Mod. 70, 3-1/2 inch pistol.
.32ACP, being semi-rimmed, also shoots nicely in a Ruger .32 H&R Magnum revolver.
I cannot find any .32ACP load data for an 80-grain bullet. Here is what I did find:
Searching LoadData.com, I see that the Lyman 313249 mould appears to produce both 75-grain and 91-grain. Didn't think the same mould for a tiny bullet could vary that much, but that's what they say the bullets weigh. They also list a 76 grain Oregon Trail RN bullet.
Suggested LoadData loads for .32 ACP cast bullets using powders I already own:
91 grain, 2.3 gr Win231, 821 fps (Lyman 313249, no info on sizing)
75 grain, 2.2 gr Win231, 970 fps (Lyman 313249, sized to .310)
75 grain, 2.0 gr Titegroup, 984 fps (Lyman 313249, sized to .310)
76 grain, 2.2 gr Win231, 960 fps (Oregon Train Cast RN, sized to .313)
76 grain, 2.0 gr Bullseye, 903 fps (Oregon Trail Cast RN, sized to .313)
QUESTION: which of these loads goes with an 80-grain .311 dia bullet onto .32ACP brass? Or does it really matter? They seem to be using more powder with a heavier bullet, which seems counterintuitive. (I always though with heavier bullets one uses less powder or overpressuring can result.)
Would you recommend a different load?
