There is a lot of 6mm’s leaving benchrest rifles and going to prs rifles now. From the 6br, the bra, brx, GT, xc, 6mmLGBTQRX123. Why are we going this route over the .243? What benefits do the cases have over the win? Brass for the .243 is everywhere. Can be made relatively easy. Feeds well from a magazine and has a standard case head. If barrel life is the concern, why couldn’t you just load to 6BR velocities? Just seems excessive to me with these super short cases that need mag spacers and tuning and specialty brass manufacturers. Or maybe I’m just a stupid dumb idiot. What gives?
