[QUOTE="Greyfox, post: 1828882, member: 10291"] I do this regularly with my 22 rimfires used for Rimfire PRS. Target distances had ranged from 25-350 yards. Yes, you can hit a 10” plate with consistency at 350 yards. Here is what I do. -I zero my rifle with an accurate load that is sub .5MOA at 50 yards. -Chronograph your load which needs to have an ES of less then 20FPS. -Use a ballistic program(Shooter, AB, Streyloc, etc). Start with a G1 BC of .130, and velocity, Shoot 200 yards. Adjust the BC in.02 increments to achieve POI. Test at maximum range desired and fine tune. This has worked very well. I can build a very accurate drop chart off the calculator, or more preferable use my G7 Ballistic RF for various ranges to 350 yards, as well as wind dopes. My preferred loads are Federal HS Gold Metal Match 40gr, and Lapua 40 Gr Center-X. Having a scope and mounting system which enables an adequate adjustment range is important. I use a Vortex AMG with 20MOA rail which gets me to 350 with the turrets. My rifle is a Savage TR with MDT chassis.
