Gas checks causing fliers
I am hoping I have found the culprit that throws a occasional flier . Yesterday evening I finished installing gas check on a few cast boolits before running them through a push through sizer . When I noticed a few seamed to have a little more space just above the gas checks . My vision is shady at best but with my prescription reading glasses + my trusty magnifying glass I thought I had got the gas checks on fully . With thumb pressure alone , but after checking 40-50 my little digital caliper showed I have been WRONG .
In a pm with Larry a wile back , he mentioned to make sure you are seating your gas check good if using a push through sizer , I thought I was but I found a dozen or so out of around a hundred that were seated flat but not pressed all the way on the base .
Thanks Larry G .
