Nobody around here uses Varget, huh?
After a couple of months "playing" we've finally nailed down the bullets for our .223's.
Oddly enough, mine seems to really like the 69 MK's- then nothing else down to 52 Nosler Competitions. The Noslers grouped pretty well, but POI was waaayyy left and low. Same promise showed with 82 gr. match Bergers (single loaded), but again POI way off.

Now it's time to play with powders I guess...

Seems though, that once you've got it down to the "best", that's all you're going to want to shoot because changing means re-zeroing the scope. Or, do you guys never stop- and constantly try something different in search of some magic combination?
