anyone try them? are they good choices or is there something better already. maybe a dasher or brx type? what type of bullets would you use? what kind of barrel life? how about velocity? I mostly will be shooting 600 yards but want to be able to shoot high B.C. I also want something that is easy on compoents as well. I already have a 6br but just wanting to try something new. Let me know what you guys think.
