I got my Tenacity 204 Ruger prairie dog rifle finished - XLR chassis, Huber trigger, and Muller works barrel. Doing load work ups I found the throats on 204s are pretty long. Almost no bullet in case to get to lands. Anyway, I thought I’d share my results from varying jump from 80 thousands to 21 thousands. 5 shot groups except the 21th is 4 At 100 yards with TBAC 9 suppressor. 39gr Sierra. Only change in the loads is jump.
