Recently found a load for my Model 70 that I like. It's a .22-250 pushing a 40gr. Blitzking around 4000 FPS. Apparently my rifle prefers to be a laser. I was hoping to shoot them a little slower, however I couldn't get the accuracy results that I wanted. When performing a ladder test on 6 different loads I noticed that my standard deviation would not drop below the 50's. How important is a low SD and more importantly what can I do to achieve that? Is it important at all at distances up to 500 yards? I appreciate any and all info you guys have. Considering this is my first post on this website, If I have missed something reading through the sticky'd posts and rules please let me know and I would be happy to correct anything.
Some specs that might be important are...
