[QUOTE="Lefty7mmstw, post: 1091165, member: 48043"] As to your velocity on the 7rem chambering with 180's, you are there as to speed... You will reach your pressure top rather soon if you aren't there already so why bother pushing. As to a re-chamber.... Yes, you can punch it out to 7x300win or 7mm stw.... The stw will net you a bit more velocity but the brass is a bit more scarce and expensive lately. If you care about the brass issue I'd go 7x300... Here's a thought; shoot the 7rem barrel out, then re-barrel with a bit bigger chambering. You are only 200 fps down from what I'm pushing 180 sierra's at out of my 7rum with a milder load of retumbo... [/QUOTE]
