Fed 150 primers did well in this revolver with last bullet so I want to work up a load using them. They give about 100 fps less velocity with same load when compared to CCI 350. I figure another 1/2 to 1 gr of powder will get the velocity back up there. I will look for consistency more than speed.
You only need the velocity back up there if it improves groups. This is a target load right? Velocity is unimportant, groups and consistency of the burn are important. You are not looking for a top end load, you are looking for the accurate load and rarely are they the same.
Yes bench technique is important, grip and follow through even more so. You must be relaxed and allow your hand and arm to simply follow the gun up in recoil with no resistance to it. Do not fight the recoil, relax and allow it to happen. If you try to beat the recoil you lose recoil wins. Hold the gun no tighter than needed to prevent trigger squeeze from pulling the sights off target, any tighter grip than that is too tight. I've tried teaching cops long range revolver accuracy and it's nearly impossible, they have years of defensive shooting ingrained and they hold the gun so tight you can see the muscles in their neck bulge. Just can't convince them to let go of the gun and relax, easy grip, relaxed arm that follows the gun up.
4 and a half inch 100 yard revolver groups is definitely an improvement and heading in the right direction. It shows the load is solid, repeatable and the gun can do it. A couple of years ago if I told you that you would be doing that you most likely would have called me a liar. Now to work on and improve the grip and follow through even more, I guarantee that you will be amazed.
