This was the first time I've Shot past 400 with this rifle. I've had this rifle 3 years but haven't spent enough time behind it and am still getting used to the ergonomics(I'm a seasoned 3-gun shooter and used to an AR). I've shot a 5 shot .44" group at 100yds with this rifle but have not been able to do it constantly. I'm pretty excited to have shot out to 780yds and I'm looking forward to going again.
Temps were in the 50's and crosswinds up to 12mph or so.
I verified velocity is around 2710fps. At 600yds I was about 1MOA low(can see evidence on the BC plate). I added an extra 1MOA to the Strelok data when engaging the 780yd plate and my elevation was pretty close. Wind was a challenge and 2 of my 5 shots went off the 780yd plate to the right.
Question:
1. To correct my Strelok data for my actual experience, I slowed the velocity down to 2660 fps in Strelok to account for the 1MOA adjustment I had to make. Is this a good practice or should I adjust another value? Maybe my Chronograph is a little fast.
Thoughts?
