[QUOTE="Hand Skills, post: 1467782, member: 103303"] What twist rate did you go with on your 7mm RM [USER=101677]@Canhunter35[/USER] ? I'm looking forward to some updates on that build! I've been thinking about ordering a Gaillard (now that I'm a Saskatchewanean) but he only does a 1:9. [USER=72601]@Creedmoor shooter[/USER] I don't have any experience with 7RM this decade, but I've been doing a ton of research for my next 7 (now between .280 and 7RM). For the latter, VV N570 looks like 'the' powder for 180's. Very similar to retumbo, but notably higher bulk density and perhaps even a hair slower burning. Seen reports of 3100fps with Berger 180's.
