[QUOTE="SMK1000plus, post: 1664798, member: 93846"] lancetkenyon is spot on! I'm running @ 24" barrels with 9" to 9.5" twists in my 7mm RMs, 3 factory rifles and the 9" twist is a Bartlein 24-1/2" SS 5R Sendero contour. I get @ 100 to 150 fps less than he is getting, across the board. All my loads are OCW developed loads and none are within a grain of maximum pressure in any of my rifles. I haven't tried the 183gr SMKs, 180gr or 184gr Hybrids though. Not really enough twist in my rifles for use here in the winter, right at sea level. I'll be installing 8" twist barrels on them as I replace their barrels. I haven't used any RL-26. H1000 and RL-23 are awesome. Those two powders produce excellent accuracy and very good velocities in all my 7mm RMs. I have loads for both and can't say that either powder is better than the other. I don't have a 264 WM so, no real-world data there. [/QUOTE]
