Loved the varget but the grass is always greener... Varget even with the hotter cci 450 primer is a great combination.
For the rebarrel I plan on 3 more inches of barrel, AI improved, and a long throat.
been thru several bolt guns thru the years, but now own just one bolt gun in .223. I've been playing around with a lot of different powders, but always seem to come right back to BLC2 and H322 with 2015BR right behind them. I did try H335, but it just didn't work out in the three or four rifles I tried it out in. I do have some rounds put together with H335 that are a little different (primers and different bullets of a similar weight).
One thing I've learned about the .222 case family over the years is that they are very reponsive to different neck tensions. Right now I'm running about .0035" of grip on the bullet. Have been down as low as .002" and as high as .0045". Seat the bullet within .003" of the lands; if not slightly into the lands. Federal primers seem to be the ticket with all the guns shooting that case family. Also the hot loads in the manual are usually not the accuracey loads your looking for. In my Remington I shoot 55 grain Vmax bullets at 3270 fps, and the load is good for another full grain of powder. I'd love to be able to shoot the 53 grain bullet, but I hunt with a 14 twist rifle. Next barrel will be a 1:10 twist.
