Nothing is wrong with the 270-winchester. I have killed lots of critters with this 270-winchester over the last 28-years.
Yes I do reload.
I have in my gun safe a 25-05, 270-win & 280-rem.
I do not see enough gain in the 280-A.I. over the 280to spend the money to have the 280 rechamberedto it?
The 25-06 & 270 are close enough ballistic wise to flip a coin for the game and area I hunt.
I was thinking the 338-06 would make a good elk / bear gun.
The 25-06 or 270 would make a fine deer / antelope gun.
The 280 is my wife's rifle, so it is off limits.
