I have also used H414 (30 06) R19 (.243 and 300 Win) BLC2 (222 Rem) and haven't had the same issues I had in my 7mm with R22. Admittedly I have spent the most time at the bench lately with the 7 and I have gotten pretty picky. Maybe the sometimes severe summer humidity is another factor in my experience as well more likely is that the others haven't seen as much variety in conditions so I haven't been as sensitive to the sensitivity. I'm not saying R 22 is bad I'm just saying that for me Retumbo seems to work better.
Mmmm.....I have never seen this....even shooting summer to winter back here.
