I'm just asking around a bit...I have a 338-06 I'm trying some different loads to see what it likes. It does not shoot the 200SST with BLC-2 as accurately as I hoped. Trying some 200 Noslers, as well as some RL-15 too. I also bought a box of 215 gamekings to try with RL-19...I have a crap pile of RL-19 so why not. Right out of the Sierra manual it claims a max load 65.8grs. I started at 59 and loaded some up a grain at a time...64 almost completely fills the case. I'm using Remington cases vs the Winchester cases the manual suggests. It's making me nervous, so I looked at my stepsons 270 loads with 150 sst's are 57gr of RL-19...I know it's a different caliber, but very similar case capacity with a lighter bullet. Am I asking for trouble here? Seems like a lot of powder under a 215gr bullet to me.
