[QUOTE="James Pearson, post: 1723464, member: 111455"] OK, the new gun appears to like the 145’s just fine. I worked up the mid range of 4064 and 4831 powders in .2gr increments and even though each round was a different powder charge, both total groups were under 3”, several rounds less than 1MOA, with to be expected mid range FPS. (2700-2840). I am going to run another series higher up the scale and include the H1000 this time. This may not be the way everyone would conduct a load build, but I’m just taking my time and analyzing the data as I go. Thanks for all the input, if anyone has anything more to add, please jump in! Also, since I shoot year round I want to stay with proven powders that are not temperature sensitive. (?) [/QUOTE]
