[QUOTE="J E Custom, post: 1390124, member: 2736"] The reason I would/do recommend trimming to the same length is for consistency. Also I would do it before any re loading/testing begins. I would agree that you may not be able to see any accuracy change from one length to another "BUT" while working up you load difference in bullet tension/grip and sizing could make a difference and lower SDs even if only by 1 or 2 numbers and eliminate or minimize the differences in the neck tension and surface area of the neck. I believe it is always best to make every component as consistent as possible when re loading ammo. I also recommend and faithfully turn all Of my necks before they are loaded the first time, so they are very true and consistent once they have been fire formed the first time. Once you find the best combination for your loads, you may decide that some part of this procedure is not necessary for the accuracy required but at least you know what the potential of your rifle is with near perfect loading. If you can load ammo that will reduce group size from 1 1/2 MOA to 1 MOA you have improved your accuracy by 33.3 %. If you can reduce a .075 thousandth group to .050 thousandths, That's only .025 thousandths but it is still an improvement of 33.3 % and well worth it to me. Turning and trimming also aides in concentricity testing loaded ammo. Leave no stone unturned J E CUSTOM [/QUOTE]
