According to Lyman, the 358430 bullet has a length from base to cannelure of .412 inches. I just got my 190 grain Hunters Supply LFP today, and I measured the distance from base to cannelure on them, and I got .410 inches to the bottom of the groove. According to the Lyman load data, I feel pretty comfortable starting at the low end and working up. If the seat depth is the same, then all other things being equal but reduced weight, I should have pretty much the same or lower pressure.
