[QUOTE="idaho elk hunter, post: 1075501, member: 68226"] The larger calibers have more bearing surface. therefore you will have to increase the load. this is shown in the 7mm vs 300 loads. You will see similar findings in bullet engineering. a 175 gr roundnose 7mm compared to a 180 gr Berger will result in the same conclusion. More bearing surface compared to little bearing surface. Hex Boron is all about the friction coefficient of bullet to barrel. [/QUOTE]
