Before I get to my questions, thanks and gratitude are in order for Devin Sinner of Sinarms and LTLR for putting forth the time and effort to develop and test what look to me to be a very promising family of wildcat cartridges. I have followed the .338SIN development with great interest and the discussion has been very educational! Since I first joined this site, I have payed close attention to LTLR's posts and have benefited greatly from his experience. In particular, LTLR has been responsible for turning my understanding of the practical long range ballistics of the .338 class cartridges on its head. Because of that, his comments on the .338SIN have really grabbed my attention. I am sold on the concept and am in the planning stages of a rifle build in this cartridge on a Ruger or commercial mauser action. Here are my questions: 1. What, exactly, do I need in the way of dies/case prep equipment to form brass and reload for this cartridge? Sources, part #'s, and case forming instructions would be very useful. I have never worked with a wildcat cartridge, so this would be a completely new world for me. 2. Does Sinarms intend to make the SIN cartridges proprietary or will the necessary chamber reamers be available for purchase? 3. What will be available from Sinarms for the .338 and 6.5SIN in terms of supplies and gunsmithing services? When are these things expected to be available? I realize that these things are still in the development stage and that solid answers to my questions may not be available for awhile yet. I just want to start the process of getting concrete enough answers to these questions to develop a realistic build plan and start saving my money. I am watching these developments with great interest and can't wait to get in the SIN game!
