Bruce this is a hotly contested topic. I've used both and I prefer plastic. No matter how many SS reels I loaded(and I worked in a prolab with rotary nitro burst, so thousands and thousands loaded probably) I couldn't keep the crimp marks out. I'd have weeks of luck but then for no apparent reason a tell tale white waxing moon would appear. I think SS is easier to load than ratchet style plastic but I have much less crimping now. I use tanks and agit very vigorously to insure even developing. Neither is a picnic and you'll just have to try and try until you've decided for yourself.(posted 8793 days ago)
