Four years, it wast the ..458 2", then with age, sore shoulder all the time, I put a .375 bl. on that action and a .375/06IMp bl.
The .458 2" one was my fovarite for 30 years, but since I picked up serial #1830 in a model .70 in .30/06, THAT one is my new favourite, in .375.06IMP.
The .375 should have been my new favourite & actually was for several years, but that old 1936 Model 70 wins this contest, overall.
