I've got my dad's old Model 7 in 308. It isn't very accurate and because it's pretty light, it definitely let's you know you pulled the trigger. I'd like to get a new barrel on it too convert it to 7mm08 for my kids to shoot deer when they are ready. I already ordered a youth stock for it. I've never had a new barrel put on a rifle before and I am not exactly sure where to start. One thing that seems somewhat confusing to me is all the different contours out there.

I'm thinking a 20", 1-9 twist, threaded for a brake or suppressor.

How would you set it up? I just want to make sure this is set up smartly.

Thanks!
