Just curious why you would only want to shoot 2130 fps (aside from the scope thing) when your Savage is well capable of launching any of the 300 gr. bullets in the 24 to 2500 fps range? I don't believe any of those trajectories are going to perfectly match your scope anyway. So whynot just use the dots that do match? Unless you can verify very low Extreme Spreads in velocity (in the order of say 20 fps or slower) you can kiss those trajectory tables good by. The last few months (I shoot 30 to 35 shots a week - yep, retired) I have been shooting a duplex load with the 300 gr. Rem. bullet which I point up in a die I made. The load is 10 gr. of 5744 under 60 gr. of H-4198. RB who posts here has shot it and highly approves of it, besides a little recoil. My last seven shot string averaged 2460 fps with an extreme spread of only 7 fps and three of those shots were exactly 2461. With that low a spread, your trajectory tables will be relavent. I have seen too many loads which run 30, 40 or 50 fps ES and they ae just going to be up and down on your target. This, of course, is and opinion, but members on Doug's board can verify it. As was mentioned, invest in a chronograph and a pair of calipers. Measure your bullet/ sabot combinations to get the right fit. Whether you are shooting a .452 or .458 diameter bullet, you should adjust your sabots so they are all the same diameter. My Savage likes a combination that measures .508 to .509". I use one patch with four drops of Rem. bore cleaner in and out and one dry patch in and out between shots. If you do not clean, they these combinations will become too tight after the first shot. I post as Richard on Doug's board.
