Finally got the shortened rifle out today and worked up some loads. Changed to AR 2206H rather than my usual AR 2208. Got 2800fps with 150gn SSTs with 47gns and 2630fps with 165gn Sierra GK HPBTs and 45.5gns.
With the 165gn load ladder test four shots made one ragged 1/2" hole with 44,44.5,45 and 45.5gns.
Have loaded a few rounds with the above velocity loads and a few with more powder for tomorrow's final test before it hopefully slays some roaring reds over the next week or three.
