Seems like most people in Alaska prefer to shoot 225 or 250 grain bullets out of their .338 caliber rifles. I'm wondering why that is?
I recently acquired my first .338 caliber rifle in a custom Winchester Model 70 chambered in 330 Dakota. When researching what bullets to try in it I came across the 210 grain TSX. It's sectional density is very close to that of a 180 grain .308 bullet, and premium 180 grain .308 bullets are considered by some to be sufficient for even big bears. Since I have personally seen a .308 180 grain TSX go clean through a brown bear's shoulders, I assume a .338 210 grain TSX is capable of the same if pushed to a similar velocity.
I understand that more bullet weight is better, but in this case I'm wondering if the extra 40 grains is unnecessary. At least in the TSX, the difference between the 210 and 225 is the absence of a boat tail in the 225. I'm thinking the benefit of the boat tail for long shooting, such as for sheep, carbiou, and goat, outweighs the extra 15 or 40 grains.
Is there something I'm missing that makes the 225 or 250 more desirable?
