Hey folks,

I have always shot 230gr LRN seated to 1.270 which works very well. I want to try 200gr SWC to mix it up.

Using in-spec cases, I have to seat the bullet to 1.07" before it will drop in and out of the barrel and head space correctly. What the heck is going on?

I scrubbed and used a lead solvent on the barrel which helped a bit, but im still confused. At 1.15" the case shoulder overhangs a little more than 1/32" unless pushed in flush.

Lyman 49th claims that 1.235 is the minimum OAL, but another 200 gr SWC in the same manual lists 1.161" as minimum.

Others online seem to be running this bullet at 1.250" just fine. Is my barrel out of spec?

The gun in question is a 1911 (STI Spartan .45ACP) with 1500-2000 rounds through it. It is all stock.
