[QUOTE="britz, post: 293407, member: 7865"] johnny, 3shot groups are a good way to start to find loads but once you get close to what you want for a load you need to duplicate your results in 5 or 10 shot groups IMHO. This doesn't mean that you should fire 10 rounds at a time! let your barrel cool between shots and put several rounds on the same target, OR do multiple 3 shot groups. We are hunting here w/ hunting rifles and there isn't a guy here who has been able to shoot at the same Elk or white tail for 10 rounds (and if they did I doubt if they would admit it lol!) We want first round hits and that is it ... right? Anywho, 1: I'd look into your rifle for bedding issues or floating issues. 2: How accurately are you seating your bullets.... (.001 or so from round to round?) 3: Is your die set up to do the bare minimum of resizing? no need to shrink your brass down to origional dimensions> 4: Are all of your brass fired the same number of times? I just recently pulled my head out of my *** and figured out that the aged brass gives different neck tension on the bullet. 5: How consistant is your brass? I'm not familiar w/ Federal gold match brass but I know that w/ my wsm win brass varies quite a bit and even my norma varied more than I was hoping for. Weight sort your brass and take one of the heaviest and one of the lightest and fill them level w/ a powder like H380 (small round ball that meters out well) and weigh the powder charge in each one several times. You'll be supprised as to how much they are different. 6: No offense meant here, but how sure are you that you are doing your part in the testing? It is hard to consistantly shoot .25" groups w/ a perfect rifle bullet combo... just think about how much your error could be. 7: How hot is your rifle when shooting? some powders are more tempermental than others when it comes to heat.
