I liked my .223 (Axis) as it got me interested in the smaller targets at longer ranges. That barrel is in a box now. The BVSS has a 6BR barrel and the Axis has the .308 that came with the BVSS. It is my cast bullet gun and I use it out to 500yd. It will probably be replaced next year since it has over 6000 rounds through it now. Not sure if I will keep it as .308, change to .30-06 or downsize to .30BR. Still primarily for cast loads.

Beyond 1000yd then you need a bit more. Some folks just bite the bullet and use the .300WM or the 6.5/284 (and several other choices depending on the competition chosen). All depends on your needs and preferences.
