The issue was with the bolt handle that attached to the bolt body by a clamped on collar. One part was splined, the other not. On some rifles the bolt handles came loose i.e. the bolt handle would come loose, rotate around the bolt body without actually rotating the bolt. There are pix online.
I read of some that were able to fire without the bolt being properly closed or properly in battery, without sufficient lug contact - meaning that bolts would be blown back.
I did some research on them as Cabelas had them for $269. Too much negative info for me.
On the other hand those that have them report very good accuracy.
