The issue here is with small measures, not the larger ones used in hunting rounds.JEBar wrote: ↑Sat Dec 10, 2022 11:20 amI'm more than a bit surprised by reports of powder charge accuracy issues .... we've been and still are using a manual Uniflow Powder Measure that came in a RCBS Rock Chucker Combo purchased back in the mid 60's .... it has 2 drums and a baffle in the hopper .... no clue how many tens if not hundreds of thousands powder charges it has dropped .... with our hunting loads we weigh and where necessary adjust each round .... over time we've used about every type of powder and don't recall any major issues
The Rock Chucker kit I bought included the Uniflow, but did not include the 2nd drum nor the baffle. I'm counting on the small measure drum we've purchased to remedy the small measure accuracy problems. Assuming it does, I would expect to see similar results, accurate ("tens if not hundreds of thousands powder charges").
Prior to tinkering with 380 loads, the smallest drop with the 'standard' drum', I was making was about 5gr up to the largest 37ish. No noticeable accuracy issues with it in that range.
