[QUOTE="nksmfamjp, post: 2719556, member: 1951"] It can. What are you looking to improve? The cartridges are designed with a bigger “head height”. Head height is basically the distance from the case mouth to the end of the bullet or lands. The whole system, magazine, throat, cartridge are all designed to have more head height. Bingo. Does it fit in the mag? Does it fit in the chamber? Sometimes the mag can be modified with a new mag or bolt stop change. The chamber can be “throated”. This is key on a custom build, even though I often fail to do this…:( Their may be no basis, but I find accurate loads at this point. Too far out seems to be unstable(except in my 6PPC). Too far in robs powder room. This said this is really a super fine detail. That isn’t well established, imo. I do similar. 0.030” for std bullets and 0.050” for monos…..except Hammers which like 0.020”, I hear and see with my own. So, what would I do to improve a 30’06. Find a std bullet you likes in the 165-180gr weight range. Seat it to 0.030” off the lands. Load a pressure ladder to find pressure signs. Back off 1 gr. Then load 20 and shoot into the target. What group and sd did I get from those 20? If that group gets bigger than 1.5”….pull the rest. Drop a grain and try again to get 20 under 1.5”. 2 fails….try a new component….bullets, then powder… [/QUOTE]
