Bought some several years ago and have just started to use it in my Rem 513T. At least 1/3 will not allow the bolt to close, about half close but require a good bit of effort and the rest seem okay. Loading or unloading a live round required so much force was afraid I would break the bolt handle. Not sure what is wrong as the rifle functions normally with CCI, some old Rem Target and Fed Auto Match. Seems like the the OAL or bullet shape is not quite right. Haven't tried the ammo in either handguns or other rifles yet.
Anyone else having issues with the M-22.
