TOM-M...are you loading on a MEC? I was wondering what bushing you useing that drops 17grns? I'm dropping 18.2 of RD on my machine which is a #32 bushing and dont have any problems with crimps and 1oz loads. I dont run into crimp issues until I get into my heavier loads which are 21.5-22 grns of GreenDot which are a #35 and #36 bushing.
