I have been using the seating die to crimp. I watched it on a you tube and watched a video about it. It looked good at least the crimp did. Glad someone said somethiong about triming the case down for these bullets. I have ordered 1000 140 gr swc just for plinking and will get back to everybody when my dies and bullets come in. I was going to get some 2400 powder but was talked out of it by the salesman at Murf's. I should have gooten some anyway because I have used it for shotgun shells in the past. I have lots of different powders but mostly for rifles loads. I HAD a Ruger M-77 22-250, and the same in 220 swift wich WERE tack drivers. these are long gone due to a devorce. I really got into bench rest shooting and have about everything to do these, even a neck turning lathe. That was about 10 years ago and am now getting back into it a little. Only rifle I have left is a 223 H&R and it is a peice of ****, at least compared to the Rugers. I know where to come for help now and will return, most likely after christmas, and try this once again. Thanks for all the info and help on everything. You guys are great.
