Not sure about the 250 vs 270 but the general consensus is that a 270 may stay in a buffalo where the 300 almost always exits. But this is not reliable enough to use in a herd situation where an A-Frame and definitely a Woodleigh will not pass through.
On a Bison I better get a clear shot with no pass through worries. That TTSX in the 375 Imp is flying about like a 150 out of a 270 Win. no short range slouch. I can get close to 2800+ fps but I am going to go one grain or so under max so no hot weather issues.

My M70 had the barrel screwed on so crooked I couldn't get a scope sighted in, Lee Haskin ran it through the custom shop and maybe put a custom barrel on it so I have in effect a factory blue printed rifle and it is a shooter.
