Don't have coal. I load using a comparator so i was 10 thou off the lands based on ogive. It was in a blaser which have a long mag and action as they accommodate bigger cartridges. 30 inch barrel probably would do it. Talk to Greg at terminator as he's a wealth of knowledge on such things and would probably know straight up whether a 7rem with 30 inch barrel would do it. I seem to remember guys getting these sort of speeds with similar length barrels and smaller case capacity cases for bench rest shooting. They use barrel length rather than lots of powder to get the speeds they want. I would imagine it helps with case life and barrel? Have a look on 7mm Cartridge Guide - 6mmBR.comhttps://www.6mmbr.com › ...
they got close or better with 7saum and wsm using long barrels.
Sorry about link not that great with computers
