[QUOTE="MagnumManiac, post: 2108627, member: 10755"] Standard length throat on a SAAMI chamber in 300WM is around 3.550” with normal bullets, and around 3.600” with VLD bullets. Given a lot of rifles for the 300 have mag boxes of 3.4” or so, you need to find a COL around 3.390” down to about 3.340”. I have found sweet spots at 3.350”, 3.375”, 3.385” & 3.390” with conventional tipped bullets and cup & core. The VLD’s 200gr & under have worked at max mag box length (minus .010”) with a little powder tuning. For longer VLD’s, I have single loaded. Cheers. [/QUOTE]
