Virgin range trip with the new 18" WOA .223 upper twisted 1:7".
Was told by "people" that the bullets I wanted to run wouldn't "work" but John from WOA told me to do it so I believed him...grin...
I ran 4 bullets: 55 Berger, 60 Vmax, 63 Sierra, and the 64 PP. All with H4895 and CCIBR4's. Maxed out at 26.0 even with the 55 and 60 and then went to 25.5 with the 63 and 64.
The 55 Berger target the range guy threw away but it shot very well with all bullet weights. As good as the 60 Vmax if not better. The target should be self explanatory...
The measurements were outside to outside so you can deduct .224 from those. Powder charges are listed. Top left and going to the right go from the 60 Vmax - 63 Sierra
Here's the 64 PP loads.
The targets were very whtie and the glare from the sun was amazingly intense. So intense that I almost left. So, take these groups for what they're worth even though they are only 3 shots anyway. H4895 is some dirty crap...
I loaded up the rest of my 25.2 Vmax load that went under .2 to shoot the rest of the varmint season if it will hold me over till this summer where I can switch powders...
Gun in question...

The rifle felt good, looked good and I am tickled with it.
