mostly been shooting 295gr pb but have shot a few bb.im kind of new to muzzleloading but learning fast.ive read alot of bad info on powerbelts and no bad info on the bb or gpb.also why only 80gr. of rs. everything i have read most recommend at least 100gr.now i would try the 405 pb but my book says nothing over 400gr. would it be safe to shoot a 405gr out of an optima pro?
