I am having the same problem with my 929 and starline brass. I have also talked to Hunter a couple of times and he told me to shoot it once and then reload again but that made no difference. I asked Hunter to call Jerry Miculek and run it by him. My gun works fine with R-P brass and TK custom moon clips and 124 grn bayou coated bullets with 3.0 grns of clays. I guess I have 75.00 of brass that won't work in a revolver.
