Re: OK.....I am a believer. 308/RL-17/208 AMAX = sweet spot
I do on occasion. I use N550 as well but I'm having better success with H4350 under the 190-215s. It takes up a lot of case capacity but it's working better than I ever expected. I'm at 48 grains under the 200 hybrids and 210 ABLRS. I think H4350 gives up a little bit of velocity to R17 but it's more temp stable, cleans easier and generates a lot less pressure at near similar velocities. I'm running 49 and 50 with the 190s. These are very compressed but despite that, I'm getting single digit extreme spreads in the Palma case lit by 205m primers.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
