Subsonic 458 data 300 to 400 grain bullets

Be careful -- low-volume ratio loads can detonate. Mangement not responsible for load data. Use at your own risk.

Subsonic 458 data 300 to 400 grain bullets

Post by Alaskapopo »

I have a 10.5 inch SBR from Tromix and a silencerco hybrid can on the way. I plan on running a lightened buffer and spring if needed But I would like to run lighter bullets I have a ton of 300 grain jhp bullets that I would love to make subsonic for the suppressor.

I found an HS6 load for 400 grain bullets. But need help with the 300 and 350s
Pat. Thanks in advance
