[QUOTE="Ricky C, post: 2029601, member: 109105"] Hey Smokey3, my load was 80 gr of 8133, I’ve used fed 215’s and the GM215’s and had very similar groups. I made a hornady comparator case from a 300 Wby case, that took a little bit of work! My chamber length using that case and the 127LRX is 4.157. I gave this load a slight crimp using a Lee crimp die. My cartridge length is is 4.123 using the Hornady comp. I also had groups just a little bigger at a length of 4.078 with everything else the same. 79 gr of Retumbo was right at one MOA. I will revisit using US869, I was getting higher velocity with it. It was the first powder I tried, got 3498 FPS with a SD of 8 with 92 grs. Kind of windy the day I shot that load and right after that I finally found 8133. So that’s what I went with for hunting season. I glass bedded the rifle too. First just the action and later a bead down the barrel channel. Good luck and Take Care [/QUOTE]
