I just went out to test the function of my 930 I was just shooting the cheap Wally world federal #8 shot. I started with 5 3" slugs then 5 2 3/4" 00 buck. Then I went rapid fire as fast as I could pull the trigger and had 2 FTE with 40 rounds of the cheap stuff. Is this normal or is there some tweaking I could do? Also I was only able to fit 4 2 3/4 shells in the mag tube. When i took apart to i noticed this wear on the mag tube where the red spring is in the barrel gas port
is this wear normal for 50 rounds? Just a break in of the blueing?
