I have a H&R Handi Rifle .204 Ruger rifle with a 6-24x50mm Swift Scope. I use it as of now for groundhogs. I am looking to begin using it for coyotes and foxes as well. I would really like to put custom turrets on my scope. This desire leads to my questions... 1.Does anybody have any recommendations on the turrets? 2. I shoot Hornady 40gr V-Max, however I do not have access to a chronograph to test muzzle velocity. Does anybody have any TRUE ballistics tests with a handi rifle or something similar (24" barrel, 1 in 12 twist rate)? Or can someone test this? Thank you all!
