Mates prc with superformance gave similar results to what you have got. Tracked down some rl26 problem solved. ES 6 and half moa.

My 284 with 162 eldm and Rl17 again similar results. Impressed by the rl26 I have some rl16 loaded up and ready to try.

Hi Bobba that gives me some sort of comfort.

What I've come to the conclusion of is Instead of a COAL of 3.252 I'll seat them to being a COAL of 3.200 and see where that gets me. They are currently at 10 thou jump with the COAL of 3.252

I'll drop the powder charge down to 53.0gr due to increased pressure and just group it and see how that goes. If it tightens up then I know I'm heading the right way, if it doesn't well it's not seating depth per se

You mention dropping the powder charge due to the "increased pressure". Where are you expecting the increase to come from?


I have a 7mm/300wsm bartlein barrel that likes 175gr eldx but as much as i want it to like the 162gr eld-m it just wont shoot it better than moa. In your case I'd just go straight to trying a different pill like the 175 or 180gr like you mention instead of persisting with the 162.

If you don't mind me asking what sort of speed vs barrel length your 7mm-300wsm
