bought a model 70 in 375 JSM..... basically after making a chamber casting and spending quite some time researching, it is a 350 rem mag necked to a 375 with a 40 degree ackley shoulder. So... I need some to screw up and some to actually use. I mean I would be interested in 5, I would be interested in 100. What are you thinking. I do appreciate you reaching out to me!
