I decided to pick up a box of the 3" LB #6 and give them a try. I have shot the 3 1/2" for a couple of years with great results. With the 3 1/2" 2 oz #6 I was getting 225 in the 10 at 40 yards with my IC .665 choke. So i shot the 3" 1 3/4 oz yesterday with a dirty barrel. At 40 yards I got 212 in the 10" and 196 in the 10". The biggest difference I see in the pattern is the 20" is not as well covered. Never the less I'm going back to 3" shells not worth the added punishment for
a dozen or so more pellets. I know i could maybe choke it down more and get higher numbers but this is good enough for me! I may try the 1 7/8 oz load if i can get a box just for giggles.
