.22 WMR. Have had four rounds that went phutt. (hornady 30gm BT ) Bullet stayed in the case, good strike on the rim, I have spoken to Edgar brothers, they have said to take them back to my RFD who will replace them.
Anyone else had some problem, I do go through a few but the whole lot of ammo I have are the same batch number, I buy them all in one lump
Have fired a good number and no problem at all ?
