Breach Plug Lesson

[typical10]

After four years of shooting the ml2 I learned another lesson. I've neither read or heard anything on this exact thing but I probally just missed it.
I'm fortunate to have a position that allows me to shoot in the mornings all summer and early fall, and I'm again preparing for a couple adventures around North America with my ml2. Last weekend I prepared my shooting box with 60 grain vials vv n120 and 300 gr. hydra cons and 300 gr Barnes. Sitting at the bench locked and loaded the rifle misfired 3 times before firing, then it was a delayed shot. All along I noticed backpressure exiting the two side holes behind the breech plug, so I put another fresh breech plug in and again misfires and backpressure releasing from the two holes behind the breechplug. However when I loaded it with 5744 and a 300 gr bullet it shot good, but still with backpressure leaving the holes, with the primer hot to the touch and expanded in the extracter.After considerable thought that night I put a brand new B/plug in, the backpressure was contained in the B/plug as it should, and the first 3 shot group of n120 & 300 gr barnes went 1 1/4 group, no misfires.
So the bottom line to this, 5744 is extremley easy to ignite comparitivly, and the b/plug /primer end does wear.

Any chance at all of a ventliner missing or completely eroded? :?:

All three vents were 50 shots or newer, all in tight. All were from your first batch. I know it's sounds crazy, but everything was in check.

Savage would likely appreciate looking at your breechplug. Likely there is distention of the breechplug threads.

Most people don't shoot enough to ever notice-- but, you bet breechplugs can wear. In fact, all barrels wear-- everytime you pull the trigger.

Those two plugs were bought together last fall, for extras. The new one was purchased in March this year. I ordered two more yesterday.

Thanks for the update. When i go hunting, the last thing i want to worry about is if the gun is going to go BANG. 5744 will be my hunting powder without a doubt. Very good post. Thanks again

How much are breechplugs for the 10 ML-II anyway? I know I always buy xtras for my other MLers and never usem so I shouldnt treat my 10 ML-II any differently. :lol:

Loggy, the last time I bought one I think it was $22.

Is this "primer pocket wear" you are referring to? :?:

 

[dwhunter]

Loggy, yep straight from Savage.

Yes, the primer pocket. Winchesters fit almost perfect, the federal primers stretch the pocket so to speak.The b/plugs that I received yesterday, federal primers will not fit unless One would do a little grinding, drilling, or dremeling the shoulder of the plug.

I have the same issue. Winchester's are a perfect fit. Federal's dont fit very well at all. No problem, i just use Winchesters.
