airedale Posted 11 hours ago Share Posted 11 hours ago So today I got out the 6.5 PRC Winchester Model 70 and the Howa Super Light 6.5 Creedmoor for sighting and ammo testing. At the end of last year's hunting season I changed the scopes out on both rifles. I went with a little more power on the Winchester mounting a Burris 4.5x14 Timberline, the Super Light Howa got the same power scope but a different model, a HD 1X5 Leupold replaced a Leupold Vari X 3 1X5. I also went with a different set of mounts on the Howa using a Tally setup. Things did not go as I had hoped, the Howa with the factory base and Millet rings shot great for me last year. The new setup presented me a problem, the HD Leupold ran out of vertical adjustment printing my groups about 4 inches high at 75 yards, I was not happy. I had two choices, go back to the original scope mounts or try to shim the rear scope ring enough to bring the point of aim down where it belonged. I chose the latter and I shimmed the scope with some scope shimming material which consisted of very thin adhesive backed aluminum foil cut to fit inside the ring. I have yet to test it out as I did not get at it right away but it should solve the problem, I aint got to go down much. I had the Winchester to test out with some handloads loaded with 120 gr Barnes, to be honest they did not group quite as good as I had hoped. The speed was right on the money, a little over 3200 FPS out of a 24 inch barrel, they were advertised to be in the 3300 FPS area out of a 26 inch Barrel. I am going to play around with the overall length and see if I can get things tightened up. I have a couple of more loads to try out if these do not do what I want. This is the kind of stuff that makes things interesting and gives great satisfaction if the problems can be ironed out. Al Quote Link to comment Share on other sites More sharing options...
