Last year I bought an NOE 454 230Gr. RN 4 cavity PB (H&G 34) for my 1911 and a revolver. I've been loading to an OAL of 1.272" with 4.4 gr of Titegroup, copying a similar Lyman profile from my Lyman manual for the length and a mid range powder charge from another of similar weight. Both guns have handled this load very well. I would like to shoot the same bullet in a couple of other semi autos, but have run into some problems with chambering. This OAL is just a wee bit too long.
I made up a couple of dummy rounds and got them to chamber in both barrels at 1.25 OAL. I realize this is only a difference of 0.022", but is that going to cause pressure problems or should I be good to go? In another thread I posted asking about this particular mold when I bought it, another poster mentioned fitting the round to the throat...
If your gun is short throated, seat a bit deeper, long throated, seat it out.
My question is, how far can I safely go before I have to start worrying about blowing something up?
