I've been working on load development for a 6.5PRC I put together. It's based in an Aero Solus action and 1" diameter, full bull, 26" 1:7 twist Preferred Barrel Blanks barrel. BixNAndy trigger. MDT chassis. Nightforce scope. I've been shooting it suppressed but I don't like the groups I've been getting so I swapped the can to another rifle and installed a tuner brake. The first test was promising. I've shot it at 1,000 and it's not bad. I'm hoping the tuner will help me turn hits into groups.

On a hot day this load is a bit too hot for my comfort level so I'll back it down a tad.

Target (100 yards). Further testing needed to be sure setting 8 repeats and is the best. 1/4" at 100 isn't terrible.

Considering it's an Aero Solus short action magnum action and a prefit barrel assembled to it by me, I think it's a good start.

I changed powder to N555 and I made a seating depth adjustment so I retested the tuner settings last weekend. I started at 0 again and ended up at 9.5 (1 mark counter clockwise).

Groups
Tuner 0: 0.217"
Tuner 2: 0.695" nope, wrong way
Tuner 9.5: 0.202"
Tuner 9.0: 0.337

I might be able to squeeze that down with further seating depth testing. Up until now this was the first time I've change seating depth since I found jam, etc. And, I should do seating depth before tuning,

Powder change was because N560 is hard on a barrel.
