Finily found a box of 10 gage 31/2" When I put a bid on this gun their were 10 gage in all the stores I have spent a week looking for a box to just shoot to get a feel for the gun and couldn't find a single one finily got one at Whole sale sports and that was the only one that they had. I also put a bid on a standare lee loader for the 10 gage 31/2 but have already been out bid. I doin't know if I want to go higher then 50 dollers though. will be retireing in about 6 more weeks and the fun should begean. Tom N
