I have a Mossy 535 and Dad has a Mossy 500. Both like a Jellyhead .660. My 535 is a thumbhole with a 20" barrel and camo. LOVE to hold it, but it doesn't pattern as well as my Dad's 500 with a 28" barrel. Yesterday, we patterned a little and then shot some skeet. With lead, my 535 can only break 100 with 3.5" shells ( I only shoot #5 shot in lead) and that is only with a Jellyhead. Dad's Mossberg 500 shot 146 hits in 10 inches at 40 yds, shooting hevi-13 3"-2oz-#6. That was a good, even pattern too. After his shot, i took the Jellyhead and shot the same hevi round out of my 535 and got 104 hits at 40 yds.
