[QUOTE="Hugnot, post: 2120286, member: 115658"] The Frankfort seater sure looks like a good deal - I think I will get one - thanks to nkyshooter! I can live without a .20 sleeve as I have a Hornady seater for the .20's. As for erosion - to FF using 8-15 grains of pistol powder & COW @ about 20K PSI compared to FF using bullets & full charges of rifle powder @ up to 60K PSI - I think the FF using bullets would erode much more. I'm thinking of all that rifle powder burning in the within the case & first 1-3 inches of barrel and generating up to 60K PSI. Bullets are expensive and scarce and most shooters like to have 100-500 rounds on hand and COW FF would save that many bullets and much scarce & expensive powder. I think of using COW FF ammo much like using factory ammo and at 60K PSI the next time its completely formed. I think a 7-8 twist .22 CM would be as good as it gets for a .22, no FF needed. I like my 6mm AI more than I thought I would. I run it at the same speed as my 6mm but at somewhat lower pressures and get better case life and almost no trimming needed. I COW FF cases in my garage shooting into a 5 foot long piece of 3 inch PVC pipe. As for trimming - just trimmed 200, .223 cases that grew almost .030 after 6 cycles, a .223 AI would have prevented that. I don't think I will go for a 6mm version of this: [URL unfurl="true"]https://www.thehuntingnews.com/what-in-the-world-is-a-22-eargesplitten-loudenboomer/[/URL] [/QUOTE]
