[QUOTE="danacobb, post: 29930, member: 1696"] First thing; I'm new to the site and long range shooting, but enjoy hering from all the very knowledgable people on this site. My question is general, but I don't understand why you get more or close to the same velecity out of larger 30 caliber (150grn) bullet, than a 270 caliber (130grn) bullet using the same case. Example: 300WSM 150grn @ 3300fps 270WSM 130grn @ 3275fps These are factory ammo specs. Are they using more powder with the 300? I don't currently hand load, but am curious about the physics behind it. Thanks, Cobber [/QUOTE]
