G1 for mine is typically around 0.150 (0.140 on one rifle, 0.163 on another). I have gone back to using Strelok mostly. If using my kestrel, I have been known to add DSF at 300 to true observations. But 0.150 is good to 200 for me. But I have had some unexplained variations using DSF before that have caused me to get bad solutions. So Strelok gets the call on the rimfire.
To note - I ALWAYS trust my chrono. When confirming before a match, I will very slightly adjust BC to account for conditions. Any large swings in BC are not done before a match. I have shot enough Team/Match, and screwed myself by making large changes, to know better.
