[QUOTE="AJ Peacock, post: 180911, member: 4885"] You have no idea what you've just asked :eek: There are so many ways to skin this cat and sometimes the discussion gets heated. Yes, small changes in powder amount can have affects on accuracy. In general, an accurate gun will shoot most ammo well. However, there are often particular loads that shoot GREAT! I've seen rifles that liked really hot loads and others that shot the most accurate with mild loads. There is a technique called a ladder test that some folks use and swear by. Others call it un-scientific and mathematically flawed. An easy and typical approach would be to determine what velocity level you are looking for. Then using a chronograph, shoot a range of 3-5 shot groups at every 1/2 grain or so over that range. If a couple really shoot well, you can try that recipe again and see if it suits your needs. Or you can then hone into that range and test every .2gr or even .1gr if you feel like it. If you need some reading, do a search on ladder test and you will get all the info your heart desires (and more). Or you can use the method above, find a nice load and be content. Merry Christmas, AJ [/QUOTE]
