no I should have stated 10ml2A Savage MLII holds the primer by the rim in the bolt. That capper wont work.
Did you mean the old Savage ML that used the modules? That is a whole other matter entirely. If it is the old module model, your vent liner might be wasted too. Those vents are much different than MLII vent liners. Not sure you can even get them any more. The plug would need to be converted to take the MLII vent liners.
I did find a guy making the old style module for $12 each.
This is my experience as well. I keep a pair of needle nose pliers in my possibles bag just in case this happens. But for me it happens less often with Federal primers.The root cause is improper headspace. The firing pin drives the primer cup into the breechplug. Then, when the charge goes off, the primer is blown partially out of the primer cup into the bolt face. The gmb work around works by driving the primer back into the primer cup with the firing pin strike.
