hi everybody, I'm about to start my first build and I have a few questions 1. My 20 year old 700 barrel is just about on its last legs, group sizes have been increasing steadily for the past few years and it is unacceptable now. there are no smiths around here and I don't really like sending gun parts through the mail, so I'm thinking a rem-age barrel might be the way to go for me. does anyone have any experience with them? 2. I'm thinking about going with 243 win, for a high BC and easily obtained brass. most of my shooting will be 600ish yards with the occasional shot out to 1000. I mostly shoot steel, but might use it for yotes or groundhogs too. is this a good caliber choice? 3. Will I have any feeding problems mounting a 243 bbl on a long action? I think the Army's M24 is built on a long action but I'm not sure. thanks for the help and expect more questions in the future.
