[QUOTE="WildRose, post: 1535715, member: 30902"] It's just a necked down 7LRM. I bought it from a fellow poster here. The dies are 7lrm hornady custom bushing dies with smaller bushings. Necking the 7LRM brass down is no problem. He was running high pressure loads with Retumbo which I don't like so I tried RL 26 and RL 33. I had to pretty well guess but a friend here ran the numbers for me on QL and got me to a safe starting load. It's a Model 70 LA with a 27" barrel. If I were going to start over though I'd just go with a straight 6.5-375 Ruger with the shorter neck, longer shoulder angle, and greater capacity. When I shoot the throat out of this one I'm hoping there will be enough room to set it back a few turns and go straight to the 6.5x375. As popular as the cartridge is and all the wildcatting being done off of the case it's a cinch that sooner rather than later we'll be getting brass from better sources. I've already talked to several manufacturers that said they were considering and/or working on it. I tried just necking down .375 Ruger brass with .338RCM and .300RCM dies which seemed like a great idea but it ends up crushing/crimping the shoulder. I'm talking to another custom die maker to see what we can come up with. Essentially the first step needs to be lengthening the OAL by squeezing down the taper and pushing the neck forward to get the shoulder angle and diameter changed and then to start stepping down the neck diameter.
