I have an old (1950's 1960's) Remington 700 in 30/06 that I want to covert to something different. The problem with the rifle is I can't get a load to shoot even halfway decent out of it. It's got a short barrel (20"?) on it with a metal butt plate. It doesn't even have a magazine plate on it, you have to empty the gun by working the action. It looks just like the picture I'm attaching. I know that most custom builders use the Remington action so I'm sure there are plenty of options out there. I have no clue where to go, how to start, or if I should just take the action somewhere and pay someone. Here are my questions: 1. I know you can easily convert a 30/06 to a 308 Norma Magnum but is it a good round? Everything I've read about them seems positive except for the brass. 2. Can it be converted to a 300 RUM or a 338WM? I've seen threads about converting to 300 WM but not the RUM or .338WM. I figure if I'm going to change the whole thing why not look at my options. 3. If it possible to do this stuff, where do I start? I worked at a gun shop/shooting range all through high school and some college and I am no gunsmith by any means! I'd like to do as much as I can myself but I will definitely take it elsewhere to get the important things worked on. BTW, I'm in Mesa, AZ if anyone is a custom builder out there that is willing to help me out!
