I'm starting to look for the pieces I need to put together a 260 to shoot the 140 Amax or Bergers. I am limited to a short action due to the stock I want is only made for them. With the longer freebore of the Match chamberings NSS offers I imagine I'll be way over magazine length when touching the lands. My question is how much would I be over mag length roughly? I plan on shooting it single shot but am curious incase I ever decide to take it out for whitetail. I plan on loading long to get as much powder in as possible (well what's needed) with the loss of capacity that comes with using Lapua brass. Thanks for any help!
