I was just wondering what method everyone used to arrive at an accurate load. I will share my method as well
1. look through the load books and select a powder that doesn't end up compressed, but fills the case very full at recommended maximum (95 % or higher fill).
2. load 2 or 3 at 1 grain below maximum and check for pressure signs when firing if this is ok then go to next step
3. determine optimum jump to lands 5@.005 off lands, 5@.010 off lands, 5@.015, ...., 5 @.050. clean after each 5 shots (you have almost broke the barrel in!)
4. take the best one from step 3 and load 5 at .002 longer oal, load 5 at .002 shorter oal, and 5 at original oal this will be the cartridge oal.
***interesting note in my rifles tests have shown that once you find the most accurate jump it doesn't matter what style or weight of bullet they will all prefer this distance from the lands!
5. cartridge length is now established, load 5 @ initial charge weight, 5 @ +.5 grains, 5 @ -.5 grains. (80 rounds at this point)
you should now know which load to use, and assuming you bought 100 brass pieces you have 20 left to load up and wow your buddies at the range. This will result in 100 once fired brass cases ready to be stoked with the most accurate load for your bullet of choice
and a nicely broken in barrel, and a knowledge of the best rifling jump for the next bullet you try thereby eliminating the the first 65 rounds from this process.
Let me hear how you do it.
