My 8 yr old boy shot his friend’s 28ga beretta A400 with shortened stock this dove season and loved it. I don’t have the coin to buy an A400 and cut it down, nor buy a constant supply of 28ga ammo. I got ahead of myself and ordered him a mossberg sa-20 bantam. The thinking was that I could match the recoil of a typical 28ga load by using a 3/4 oz 20 ga load. I have already ordered a box of Fiocci extra low recoil 20ga which is a 3/4oz load of 7.5 shot at 1075 velocity. Is there any chance in hell of this load cycling the action? Or anything I can do to MAKE it work? I’m now afraid I’ll have to sell it and go to a 28ga. Any ideas?
