[QUOTE="J E Custom, post: 1677533, member: 2736"] It is just My opinion based on experience with different primers that different primers will/can Improve SDs. What works best for me is to take a load with already good SDs because the bullet weight, powder and case capacity are a good combination and work well combined. armed with an already good load, I chose other brands of primers that are in the same class and Brisance (Only change one component at a time) I like to shoot at least 5 rounds of each test loads, starting with a clean barrel each time. This assures an apples to apples test. Revue the results and look for the best SD. what this test method tells you is which primer is best for that load with that group of components. It may also encourage you to try other powders with the same bullet weight and case capacity to find out if there are better primers for that cartridge using that Primer. This also tells you that a particular primer works better for that Powder. Even slight improvements in SDs do contribute to better accuracy at longer distances, where at close distance it is hard to recognize this improvement. One such rifle of mine went from a SD of .07 to .05 and improved the group size from .071 5 shots @ 100 yards to .054 Not a huge improvement in ether SDs or group size bur a large Percentage improvement and at distances of 400 to 1000 yards, a significant improvement. Test your rifle and find out what primer it likes best. Just because someone else uses one brand, doesn't mean your rifle will like the same primer. The match grade primers "Should" be better because of quality control requirements. But don't depend on this, because different combinations of powders, bullets, cases react differently and in many cases the standard primer can/will produce better results. J E CUSTOM [/QUOTE]
