[QUOTE="MudRunner2005, post: 919161, member: 12995"] I can post a pic of a .300 and 7RM when I get home from work in a little bit. Still at the office now. They look VERY close in size, but apparantly the .300 hold just a bit more powder. I was a little bit off I was simply going by my looking at the 2 cases side by side. With that said, here's the facts... According to Chuck Hawks, the case capacities are: 7mm RemMag - 83.2 gr. 300 WinMag - 90.4 gr. So, that means the .300 WM only holds 7.2 more grains than the 7mm RM. Not enough to make me rechamber my rifle... However, the 7mm STW jumps it on up to 97 gr of case capacity. Now that would be worth the jump from 7mmRM to 7mmSTW. :D [/QUOTE]
