Mine is a 1941 model 70 converted to left hand. I sent it to Cliff Labounty to be rebored to 35 Whelen. Loves any 250 grain bullet and 56 grains of 4320. I tried some old 275 grain Hornady RN. They shot okay but not as well as the 250s. One of them made one bull moose surrender.
Three caribou fell to 250 grain partitions. All one and done.
