[QUOTE="Max Heat, post: 675226, member: 43153"] I'm looking for WAY more "trick" than 130's (or even 140's) @ 3500. That's "chump change", in my book. The standard remington 7mag can pull THAT off, using RL19. But since that IS what I already have, I need significantly more than that to step up TO, in order to make it worthwhile. I've heard that getting 180's to fly at 3500 is a piece of cake for 7RUM. But that's the high end of the 7's weight range. I'm looking at working near the lower end of that range, but with maximum "heat" numbers on what the muzzle spits out. I'm taking about 120's flying at nearly 4 grand, using 96-97gr of RL25. My goal is to work up to that. All I need, is something to work WITH. But those dang stories I keep hearing about over-sized or swelled RUM chambers do have a tempering effect on my thoughts of going small shank RUM, via re-chambering my existing 7RM barrel. But for a burn-it-up-in-no-time barrel, it does appear to be the most eligible candidate. Then I can take my time on finding the long-and-fat barreled big-shank 7RUM setup that I am truly seeking. Roughly how much DOES it cost to have a barrel machined out to a larger/longer chamber? [/QUOTE]
