[QUOTE="Huntnful, post: 3084488, member: 116563"] Just starting a fresh thread to clean up the info gathered through all the testing in the last thread to make it easier to find in one post. I'll also document the season with this rifle. Since this is its final configuration… maybe hahaha. But for a brief update, I have a forming barrel now. Goal for the build was to shoot 180 ELDM's with H1000. I already knew good charge weights based off of previous barrels. But I have also gotten good charge weights on several bullets and powders that I will share here at the end as well as velocities.
