[QUOTE="Pdvdh, post: 372864, member: 4191"] [b]Re: RL-17 in 280 RCBS Data[/b] One last tidbit of info on [B]RL-17 [/B]powder and my [B]280 RCBS Improved[/B]. I was at the range chronographing again today. The ES and SD are too excessive for LRH. Shot 4 rounds at 54.4 grains RL-17 with 168 VLDs and Fed 210M primers. Average MV = 2940fps ES = 58 SD = 25 I'm giving up on RL-17 in this rifle. I think I'll be using H1000 or Retumbo. Retumbo gives the best velocity but the ES & SD is running higher than with H1000.
