[QUOTE="joeycoates, post: 878695, member: 72330"] The max charge that I shot was 69.0gr of H1000 which resulted in 2899fps average. I have listed some additional data below. At .010 off it shot a .75" with 65.0gr, .60" with 66.0gr, .15" with 67.0gr and .80" with 68.0gr. On a different day it shot over 1.00" with 69.0gr but I kind of do not count that as it was a different day and thus not a back to back comparison. Another thing that was kind of funny is that every 1gr of H1000 equals just about 50fps. Averages were: 65gr: 2712fps 66gr: 2747fps 67gr: 2798fps 68gr: 2850fps 69gr: 2899fps (different day though) When I shot the 69.0gr rounds the primers were starting to flatten out, but were not cratering. No sticky bolt or ejector marks etc. I can probably go up past 69.0gr, but I do not know how much. According to most manuals I have seen this is starting to get close to max recommended loads. I have the following powders I can try as well. RL-22 IMR 4381 IMR 4850 I might just stick with what I have until I have a Lilja or Brux barrel installed. Might switch to 7mm STW or something else at that point as well, but that is something to explore in the future. [/QUOTE]
