Outdoorfan, I'm sure your guns probably shoot them well. Here is a link explaining how the bullet diameter either fits your gun or not....

I tried the .243 original blue coated non banded all copper barnes when they came out back around 99'. They hit the paper sideways and were keyholeing out of a brand new 700 VLS that will shoot .3"s at 200 yards with several of my jacketed hand loads. I figured I'd try some of the new banded TSX in my 300 RUM when they first came out. Bought them when the first year Barnes released them but never tried the bullets till last year along with some .358 180 grain TSX from another member I traded some of my group buy .358 HPs for. Three 3.5" groups or larger were the norm at 100 yards with both guns. I slugged both barrels to find out the whelen barrel was a thousands larger in diameter than the .358 Barnes and same with the 300 rum. Imo Barnes should offer various size diameters (ex .358,.359,.360) for proper fitment. I still both .308 180 grain and .180 grain .358 tsx bullets left. Shot a few of each I'm group testing. Would sell or trade for j words. I have the 1st year Barnes reloading manual as well that i will trade or sell with them.
