Took them out today in the CVA Wolf with charges of 70 80 and 90gr blackhorn209 with the lubed wads. 70 and 80 were in the 7 1/2" group range @ 60 yards, 90 grains shrunk it to 5" in a triangle form, the others were horizontal spread. That told me i was getting close to what it wanted but good grief! Them 320's kick like a mule. Decided to quit while i was having a good day and go back out some other time with the more comfy 250gr REALs.
