Hi,
First off I'm a long time lurker but this is my first post. If this subject has been written about before I apologize but I haven't come across it yet.
I just recently acquired a new rossi 92 in 45 colt with a 16" barrel. I had the idea of possibly threading it for a suppressor and was curious about heavy bullet sub-sonic loads for it. I would like to shoot 300gr or bigger bullets through it but have run into a problem... All of the information i have found regarding heavy bullets were for ruger only loads that leave a carbine barrel faster than 1500fps. Most all of these loads have used powders like h110 that can't be loaded less than 90% case capacity. Any time a heavy bullet is mentioned in an article the author states they see no reason to load any slower.
With that said I currently have universal, blue dot, and trail boss powder to work with. I wouldn't mind picking something up along the lines of 2400 or h4227 if i needed to. If i were to pick up premade cast bullets the beartooth 330gr wfnpb would probably be my first choice. Where would i start to get 1050fps out of a 16" barrel? Thanks in advance!
