I had some questions on the 22 BR. With 90grn bullets, would h4350 work with success? My dad wants a good 600 yard gun with little recoil. We already have a good amount of h4350 already. Also, how will the recoil compare to a 24" 6.5x47 shooting 130s vs. a 22br shooting 90grn. This would be an f-open gun so it will be around 20lbs.
