I do a high shoulder or mid shoulder hit with the 220s. Barrel twist?? I have an original .300 Whisper Contender barrel from 1980s. Never asked the twist. My barrel shoots 220 RN, 240,220, 250 HPBTs to the same POA. The 186 Lehighs shoot 1 mildot higher than the other bullets (flatter trajectory, lighter bullet). Mildot scope is a must. On my scope each dot is 25 yards different in trajectory on 8X. Makes it easy. Range the game, put the right dot on it. DEAD. That's how I did the 240 yd. deer. Changing the power of the scope will make your dots wrong. Once you figure out the 25 yd. difference for each dot you have to stay on the same dot. My friend's Blackout uses 10X to get each dot 25 yds. apart.
Load data?? Newer subsonic barrels take a slightly different load than older barrels & brand of barrels take different loads to be subsonic.
What JD told me was to start with 12.0 gr. WW296, load several rounds with 1/2 gr. less powder & shoot them in YOUR suppressed gun. When the load gets "quiet", that's your load. The load for my personal suppressed Whisper is lower than a friend's suppressed Blackout by 1/2 gr.
