RE: new .22 mag loads
I've been useing the Rem's for a couple years now, they shoot very good in my 597M and the gun has not jammed even one time since new.
I've shot several pest around here includeing several groundhogs in the garden, that load really anchors them!! Longest shot i've made with them isn't all that long at about 80 yards, but i think they will work well on longer shots too.
So far it's all i'm useing in this rifle.
