Re: .338 RUM and 250gr Sierra Game King?
I used the 250g SBT this year out of my DE 338 EDGE at 3050fps on a spike at 550 yards. 1 shot and he was DRT, high high shoulder hit, few inches below spine, took his spine out left about 2-3" exit, but didn't have to go through a whole lot granted.
This was first year we used the 250g SBT, we were previously using the 300g SMK, but wanted to drop down to a lighter bullet due to recoil. I figured the 250g SBT was the best compromise of BC, accuracy, and price.
The 300g SMK is awesome bullet though. You just cant beat that BC and the energy. Its on game performance is great from what We've seen on 4 bull elk as well. We've taken 3 spikes and a 6x6 with the 300g SMK at 2825fps at ranges of 500, 700, 900, and 915, 3 of the 4 were DRT, exits size of silver dollar, insides soup, not much more you can ask for.
