I have a Remington 1100 Tac -2 and about fifty rounds of Winchester ranger 2 3/4 00 buck as well as Remington express LE 00 buck. I have never owned a semi auto shotgun, is there any tried and try method to check for reliable functioning while shooting. I know fifty rounds may not tell the tell, what do you all shoot in strings of 2 or 3 our whats the best course of fire?
