I recently found this forum and it is phenominal! I've searched this forum and the web in general and haven't been able to find the answers to my questions. I am wanting to build a 300 win mag, 338 lapua or 338 rum (or something comparable). My question is, can I build any of these from a Savage 7mm mag donor? If so, which one(s)? If not, what would be a good Savage rifle to build from? I am wanting the rifle mostly for tactical training but possibly for hunting large game at some point. I am wanting to shoot papaer out to over 1k. Hunting will be closer distances. This will be my first build so I'm open to any and all (constructive) criticism/suggestions or whatever you have. Thank you!
