Just received my 357 Sig barrel for my P229 started to load a few hundred rounds then ran into a conflict. Using my Speer #14 manual picked up some Accurate #9 set up my scale for 13.8 grs. (Mid range from low to high). I noticed the case was full after seating a Remington 125 JHP to OAL of 1.140 and it’s a compressed load. The Speer manual does not indicate a compressed load with any amount of AA#9. Went on Accurate website to check the data, Speer starting load for AA#9 and 125 JHP is 13.1 and Accurate MAX load is 13.0 that’s a huge discrepancy. :banghead: So I am not sure about my 13.8 loads. Has anyone loaded 357 Sig using AA #9 and are they compressed loads? Or am I missing something, just don’t want my P229 to go boom.
