CK Arms on factory 115


Recommended Posts

I have about 2500 rounds of 9 through my Thunder 5.5 in the last few years. Had to break it in about 50 rounds with factory ammo and it went right to eating 130 PF loads. Steel challenge loads were not quite up to reliability, but I never tried to tune to them either. You should be able to eat that 115 right from the break in period. Just pay attention to the extractor instructions from Bobby and you will never regret the Thunder. It's a piece of art.
