My understanding is that it is kind of like an improved version of IMR4064.I bought some that was on sale for $22 or$23 a pound last year and tried it in my 7mm08,and was disappointed with accuracy,and gave up on it because I already had plenty of accurate ammo loaded with 4064 for last deer season..I realize now that the accuracy issue is probably not the powders fault .I had bought some 139gr Interlock blems from Midway a few years ago,and they shot great over 4064.They were flatbase,but the ones I bought in town are boat tail .I can't get them to shoot to my satisfaction with 4064 either..I wouldn't think the twist on any 7-08 would be so slow as to be finicky with 139s,but mine is having issues with them for some reason.
