Newbe here,
Just gotmy new .32 acp dies from Lee and want to start reloading them. Nobody in my area has any bullets in stock. Midway has them but they are listed as 71 fmj ( .311 and .312 inches in diameter) Miked up some factory stuff and they mike to .307 in. What gives with this? I dont want any excess pressure by putting a fat bullet in the tube. I've also noticed that there are two sizes in .45 acp also. I haven"t started reloading them yet as the weapon is in the hospital for repairs: I'll post that problem in the auto section under --- Taurus in hospital for any one interested in a faulty parts on the 1911

thanks for any help Howie

What is the diameter of the expander? Should be about .310" [COLOR="Blue"] [COLOR="Red"]My guess is >Bullet diameter is .312" Sierra, Hornady, Speer make them. Get the correct weight.

Your measurement was taken on the diminishing diameter that's outside the case. If you were to pull a bullet it should measure the .311 or .312 that it's supposed to be.
I reload 32 ACP too, but I cast my own 77gr bullets.

Yes, that is the right bullet for 32 ACP.

Yep. You did not measure the bullet where it is full diameter.



.451 for jacketed in .45 ACP

.452 for lead in .45 ACP (and usually plated as well)

.357 for jacketed in .38 Spl and .357 Mag

.358 for lead in .38 Spl and .357 Mag

etc, etc......although for the best performance lead is sized to the gun. In revolvers this generally will differ more than for auto's......generally.
