In my opinion plunger style inlines with a 209 primer are just plain dangerous. The same plunger type gun with a #11 ignition i think is great for those that need to use it.
Again, just my opinion and i would like to here yours.
Oh man! have you opened another can of worms...
Open breech plunger guns or even the older open breech bolt appearing guns such as the Remington 700ml, Ruger 77, and several CVA's are really a plunger action inside the bolt housing.
Any of these guns I considered somewhat of a safety concern when using a 209 primer either bare prime or a primer inside a FPJ. Not sure I would go to the dangerous label, but certainly a concern for ME...
If you look at the design of the 'plunger gun' hammers including the older bolt type guns. The plunger has a cavity to cover the explosion of the cap on the post and even when blow back causes the hammer move back from the nipple the cap tends to stay inside the cavity and at the end of the shot you may finds parts of the cap laying in the bottom of reciever.
MOST hammer assemblies that shoot a 209 primer do not have this same cavity to the extent the cap hammers have.
I have shot a lot of 209's from different styles of plunger guns. Normally using T7 powder you do not get the blow back pressure on the nose of the primer you can get with BH a progressive burn powder. But even then the only way I would consider shooting a plunger style gun with an open breech is with a FPJ around the primer to hold it together or with a metal shroud that coompletely surrounds and contains the possible flying parts.
This picture shows the shroud installed on a Remington Bolt gun which is really a plunger gun... This metal shroud keeps all the parts in the breech area -
IF they were to come apart or be pushed out of the breech plug.
If you look at these bare primers closely in these pictures I think you can see the possibility of the possible flying part idea...
If you look at this picture of FPJ's you can see that the primers tend to say intact even though the FPJ is blown off the post and may become somewhat of a projectile itself.
I do have some additional pictures of this problem on my other computer that I will add as soon as I can get to the other computer.
Just to add, I personally after all the experiances that i have had prefer to shoot caps on a plunger - even though I violate that statement with the White Umag. But after shooting it last week I had all but decided to move back to a #11 in that gun also...
Stay tuned for some additional pictures of a MK 85 shooting bare primers... not good...
