I have a batch of cast bullets I made using a Lee 6 cavity mold(228 grain, truncated cone bullet). Using Bullseye, page 671 of Modern Reloading says seat to 1.190", over 4 grains(using data for 230 grain lead, no listing for 228)I have a Remington 1911, and if I seat to that length the bullet hits the edge of my chamber and prevents fully chambering. I have to go quite a bit shorter to get them to "fit" my chamber. If I seat deeply enough that all bore-diameter lead is inside the case, the length is more like 1.163". I have to seat them this deep to avoid the bullet's shoulder hanging up on the edge of my chamber. A friend of mine has the same problem in his high round count RIA 1911. The bullets have gone through a sizer to make sure they are .452", so it's not an oversize bullet issue. Is the bullet meant more for ,45 Colt and it's a bad shape for ACP? What else could we check?

Good answer, except I think you meant to say, seat bullet ogive 1/32nd off case mouth. Welcome to forum.

OAL is not manual specific, it is firearm specific. Your handloads need to feed, fit and fire. Find the OAL that works for you and forget what the manual says, they did not use your firearm in their tests. Then start low and work up. After all, if your ammo doesn't fit and fire, there is no need to worry about pressure.

Tried that. The Remington chamber has such a sharp edge to it that I have to seat fully as I described. I did back off the charge a bit from the recommended 4 grains and fired a few with no signs of overpressure on the case head or primer pocket so they SEEM ok.

Bearing surface with lead dictates your OAL. OAL rules get tossed out the window, and load work up comes back into play.

Too much bearing surface beyond the case mouth ends up jammed into the taper of the throat as you have found out.
