Hey Bronco, glad to see your considering the #1, they are my favorite.
My 6mm started as a 270 international but the muzzle blast was more than I liked for the load I'm using. Any short bbl rifle can have that issue. One advantage to a B is the 26" bbl. A few extra fps in a package that is shorter than most standard bolts by about 2 1/2"'s.
The 270B I have used for over 20 years. When I first got it I did some bedding on the fore end and it would do <3/4' at 100. After 20 years it now does about 1 1/2", I've played with the load but I think thats all she's got anymore. More than enough for me with a 300' limit. If you really need to shoot small groups be aware that the quarter rib, where the scope mounts, expands at a little differant rate than the bbl. This seems to cause a "flyer" after about three shots or so, depending on your load. There are bbl tuning devices to be had but I have never used one. Suppossed to work great to shrink your group...ya never know. The ejector is "tunable" and if you have it set up that brass is "leaving" over your left shoulder. Set it light and it's great at the range if you reload. The only real problem I have had was my own fault. Long ago ...I wasnt setting the sizer properly and I had a few cases "stick' in the chamber
Of course it only happened once or twice but what a pain... and never at the range..only when hunting. Solved that one fast>>
