i'm shooting 100grns of bh209 in my triumph with the 295 powerbelt hp and win 209 primers. very clean,no buildup,1 1/2in grps at 100yds.

i have read on other sites that it seems more corrosive than advertised. rust forms fairly soon if not cleaned. i haven't had that problem but ,my barrel has been treated with ULTRA BORE COAT. that should keep it from rusting.
