Looks to be a more normal throat - 160's seated to the rifling leaves the bullet bases at or just below the neck/shoulder junction. My No. 1A 7x57 is throated much longer barely holding on to a 160 seated to the rifling.


J Gray a buddy of mine has one of those 1A's in 7x57 it absolutely loved factory WW 175 gr RN's. I had a box and we tried them they grouped well and I gave him the box for a cow buffalo hunt , he only had to shoot once. They'll probably kill some depredation whitetail does this winter. MB
