I shoot an FN Mauser 98 in 7X57 that was made in 1952. My "go to" load is a 160 grain Partition with 47 grains of H4350, WLR primer and R-P brass. I haven't chrono'd it, but it's my rifle of choice here in Utah for deer, antelope, elk, bear and if I can ever draw a moose tag, I'll take it on that hunt too. Very little can't be done with a 7X57 and a 160 grain Partition. Sometimes shooting range "experts" are idiots. Lord knows there are plenty of them around. Remember the definition of "expert" An ex is a has been and a spurt is a drip under pressure.
