Got out today and really got to ring her out a little bit! I loaded 15 cartridges, all with the 180gr. hybrids, starting with 58.5 grains of 4831sc going up .5 grains at a time up to 60.5 grains.
60.5 I believe is a pretty safe max. load in this cartridge. The primers were getting flat and the bolt lift was starting to get stiffer, but still not bad at all. Also there were absolutely no ejector marks at all. Time will tell but I think this load will show to have good primer pocket life as well. Also, this is a slightly compressed load, so if do anything different I will probably start with a different powder.
Here are the results starting with a clean barrel:
58.5: 2735 2824 2828
59.0: 2855 2851 2837
59.5: 2866 2873 2882
60.0: 2893 2903 2906
60.5: 2923 2912 2932
