[QUOTE="swampratt, post: 3051482, member: 15054"] Phadrian stated he read that small primer was 50fps different. Ok I get that but I was stating some powders that could be true. some powders it may not be true. At 20 feet away just about any gun will shoot say a paper plate size group on a bad day. 20 feet is not a good distance for testing longer distance things. Just like a ladder test with my .223 at 100 yards 2.5gr of powder difference is under 1" group. Take that to 200 yards and get 8" group ..But load all the same powder and get .75" at 100 and 1" at 200 yards. The little imperfections or say case thickness difference will not show up at short distances like they do at long distances. And I guarantee you there is a huge difference in case thickness and Alloy makeup in different head stamp rifle and pistol cases. Go to lexington and take your 45acp loads with mixed cases and shoot at clays or paper plates at 100 yards. Now shoot just remington or just winchester cases and see what happens. When dirt flies 7 feet from the target to the right and then 8 feet to the left and high with mixed cases you will know what I am talking about. Or maybe my guns are picky. My 357 mag likes winchester cases best. Others do not group as well. It is what it is. I have loads for the 357 that shoot great at 20 yards.. under 2".. but at 100 they are barn door size. Then i have my 100-200 yard load that shoots basketball size at 20 yards but tightens up way out.. same stinking 170gr lead bullet same case but different powder and primer.. odd things happen. Just get out and shoot and see what your results are.. keep good records of everything. [/QUOTE]
