Re: 265 TTSX in 338
Id stick with the 300 SMK for wind bucking abilities at LR period, thats why you had it built around that bullet, and for the shear energy, right??
Unless your an expert wind reader, you need all the advantage you can get on your side.
At LR, the least of your worries is how flat shooting something is, thats what a rangefinder and target knobs are for. Your main worry is wind which im sure your well aware of, and nothing matches the 300g SMK, especially not a Barnes...I wouldn't shoot them if my life depended on it.
Biggest exit hole I ever saw in a deer was from a 100g XLC from my 25-06 at 3400fps. Buck was about 150 yards, bullet entered the onside shoulder and exited the offside shoulder leaving a pie plate size exit hole, could not believe it.
