This is a great thread and nitestalket is right, I first heard about nerve damage and hair line fractures AFTER,the 454 Casul came out. Great marketing and people were buying them w/o knowing they bite at both ends..
What brand or model of glove do you use ? Most I've seen have very little padding or gel. G&A had an article on this topic and they said Elmer rationed his hot 44 loads to approx 600 a year.
IMHO - I'm not sure Elmer rationed anything but it was an interesting read. I'm using a weight lifters glove right now and it's not very effective.
