Just got myself this Spanish 1940's model 98 Mauser in 8x57mmJS It shoots very well from the few shots I've fired out of it so far. My question is while the fired mil-surp (1952 corrosive Turkish) looks fine, the Winchester soft tips out of the three I've fired the primers have backed out a little bit on two of them. the Winchesters are a little shorter than the Turkish ammo and seem to have a much softer primer, they are the same length up to the top of the shoulder it's just the neck is longer. Any ideas why the primers back out? the ammo is very accurate going by the small sample I've fired. I know the Win ammo is loaded to very low pressure (that Turkish stuff is not :lol: ), I've got some Highland 196 grain soft points on order so it will be interesting to see how that goes.
