[QUOTE="Lefty7mmstw, post: 692310, member: 48043"] You are still close to the lands. This big of round needs .2" or so to smooth out the initial pressure spike; it's not a 308 where you can bury the bullet in the lands and get away with it. Get much more overbore and you'll need to be nearly 1/2" off the lands to smooth out the pressures(257 roy or 7 rum). I would try a few rem rum cases if you can to see if it goes away too. Light oil shouldn't be an issue; I have always used a light oil or hoppes and then run 1 dry patch afterwards leaving some in. I've Never had an issue. [/QUOTE]
