Sharpshooter
I've searched the interwebz for awhile looking for what others are loading for their 20in barrel bolt gun. Since I haven't found much I thought I could help someone else by sharing mine.
Remington 700 w/ 20in barrel 1-10 twist
168 sierra MK
42.0gr of IMR 4064
COL 2.800
Win Primers
Velocity averages 2500 10 feet from muzzle
I can get extremely good groups out of this. My problem is the velocity. Applied Ballistics says it goes subsonic a little after 800yds.
My other problem is that loads of 43.0gr of 4064 runs awful through my gun.
Should I start from 42.0 and work my way up and stop when my groups start to open up and hope my velocity increases enough?
Or should I go down on bullet weight?
Or not worry about it?
If you have a 20in barrel please share what you loading.
