Just been out to zero my Browning A bolt in preparation for a days stalking in March. 100gr federal powershock, safety off, 1st round down range, good hit, 1" above at 100m, re-cock, bloody bolt won't lift high enough to come back, big stone later, handle back round ejected, same again, same problem, cycle live rounds no firing, all good, try again, same problem. Try 58gr V max, same problem. Bolt will not lift high enough to come back, on closer inspection cases are all fine, no blackening, however, the paint seems to be chipped at the top of the bolt lift and receiver area.
Any ideas, still under warranty.
