I shoot 111 grains of Rotumbo powder with 180 grain Accubonds and Fed Gold primers
I'm going to go up to 200 grain Accubond bullets based on everything I've read on this site.
I have a crappy chrohograph so I'm not totally confident in the reading, but I show 3410 fps.
I'm not an expert on barrel life but I think barrel life depends on the type of barrel, letting the barrel cool between shots, etc.
I'm sure others will have better takes on barrel life.
