Sarge,
Thanks for the reality check. I've put about 1500 125 grain BBIs through my Trubor and like it ok, but I tried some 115 grain HAP and liked the snap more than the push of 125s. Cleaned the comp and used hornady one shot every 50 or so rounds and it worked fine.
I'm getting a FGW open gun soon and wanted to make sure I wasn't neglecting to try 115s. Besides, cheaper bullets equals more training, right?
