17 hmr 20grain by Winchester
I purchased several boxes of Winchester 17hmr XTP 20 grain.
Almost all , after firing had split cases and had to be pushed out of the chamber with a cleaning rod, why ? I even had some that the round was not seated in the case and gun powder was spilling out of them, why ?
I also had some CCI A17 and CCI 17 hmr and did a comparing between CCI and Winchester.
CCI--- not 1 split case.
Anyone help me out with what caused the split cases and other bad rounds.
