Re: barrel contour and length

I had a Pacnor #8 25" in an McMillan A3 and it was very barrel heavy and deffinatly not a run and gun rifle. So if you think that you might ever be inclined to go play run and gun in a match with it, you might go with a lighter contour like the Sendro or Varmint contour....or have it fluted to try to keep the balance.
For length I was able to work extremly well with the 25" barrel, 72gr of RL22 got 3050FPS average and that was a way light load compared to what it could handle. Also consider that almost all reloading manuals list velocities off of a 24" barrel....I think that 24" is plenty long enough but that's me.
If you want to have the barrel there ready to put on make sure you get a 1-10" twist. But to actually need to rebarrel, I know people have gotten great life out of 300WM, and it isn't just how hard you push the bullet, even more damage comes from "stringing" or shooting just as fast as you can run the bolt.
Shooting buddy burned a 6x47 barrel if 1200rds.....he liked to string! It was 1200rds right Tribe?

i don't plan on run and gun not exactly what that is but i can imagine. i tried to see what twist my barrel was and if i remember right it was like 11.5 iirc it didn't sound right.barrel is stainless and code on tube said it was made in 1969 what twist options could i have?
