I was worried when I bought my A-Bolt Stainless Stalker in 223 WSSM with all the reports of barrel burn out. This was happening with < 500 rounds. Also all the rumors about changing barrels on an A-Bolt. Would I be stuck with a boat anchor? I called Browning and spoke with a tech guy, he seemed to have his s**t together. Again this was several years ago when the WSSM was the new kid on the block. I have well over 500 rounds sent down my barrel and it is still perfect, it does not get range time but hunting time so I am sure it will last me my life time. Browning states it will be good for 2000+ rounds, same as a 22-250. Also I shoot 64 grain Winchester Power Points at around 3500 fps, not 45 grains at 4000 fps.
