EC tuner brake update 300 PRC:
So I settled on a load in a velocity load with low es/sd numbers. I went a shot today and used the tuner. The first was the load at 0 on the brake. About 3/4” CTC. Turned the tuner to “1” (which is two marks) then to 2 and so on. You can see as I turned the 2 shot groups consistently shrunk. For those guys that are “well you have to have 3 or 5 shot groups”. Read the directions.
#5 needs explained. I was waiting on the barrel to cool a bit before I shot. I read a work email… bad choice. I know when I shot those 2 circled they were bad pulls as my brain was still thinking about the email. Seeing the tightening consistency of the prior shots. I re-shot that setting.
Then number 6 is 2 shots 1 hole.I decided to stop there. I am convinced this thing tunes! And felt like the brake would really well for recoil reduction.
Side note I didn’t worry about zeroing before shooting.
