As most 357 (and Lyman 358429 casters) already know, this bullet is too long for many cylinders, my Old Model Blackhawk included. I would like to have a medium-heavy load unsing H-110 and this bullet but given that I need to either use Special cases or crimp over the front band (effectively getting you back to close to 38 Special case capacity when that same bullet is crimped in the crimp groove of a Special case), there is no publeshed loading data.
Does anyone have any experience with H-110 and this bullet under similar circumstances - either crimping over the shoulder or using Special cases? My sense is that you should NOT just follow 357 mag loading data if you crimp over the shoulder since case capacity is a significant variable impacting pressure.
Thanks,
Ed
