I know this is a odor problem but I'm having it now I am starting to see gas cutting on my Savage breech plug. It's not bad yet. I have ordered me another plug have you got any suggestions on keeping this one from doing this.this plug has around 300 shots through it.

That is a problem Savage has always had. Problem is the sealing surface is to small on this plug that's why we got away from that style plug and went with the shoulder style plug which seals in the rear of the plug that took care of the gas cutting problem. When you replace your barrel go with the shoulder style plug and you will be happy.
Hank actually made a really nice video on breech plugs and how they seal its worth watching you will never get a front sealing plug to seal up under pressure when the powder charge goes off the barrel stretches slightly and the plug also can move slightly depending on how good the plug fits the factory threads it could move a lot under pressure once there is even a slight gap when ignition takes place the hot gasses will enter it and it will start to produce flame cutting.
One of the very first ML'S I made had a front sealing Savage style plug I had flame cutting problems with that plug so I used throw away thin washers between the face of the breech plug and the barrel it did help save the plug but it was a poor fix the shoulder style breech plug is a way better design.

I had to do the same thing with a Knight . I annealed copper washers to use as sort of a gasket between my plug and barrel face . That was the only way i could get my plug to seal and stop the gas cutting . It works but washers have to be changed out after every range sesson . Pain in the butt shoulder plugs are much better .

+1 on the rear sealing plug.
I have had the same issue with my Savage that I used to own. A really long story but the end of the line for the rifle was the scrap heap. Savage rebarreled and installed a new plug this past November on my ML2 because the original one was damaged (plug and barrel both) by gas cutting. Well when they test fired the rifle with the new barrel and plug the breech plug leaked during their test firing! I noticed imediatly when I opened the bolt and looked at the bolt face when I got the gun back that there was never seize from the plug threads, black with powder residue, blown all over the bolt face! Peeved indeed I was! You could also see in several places down the unthreaded portion of the plug carbon residue from the gas flowing down the side of the plug. The rifle went right back to them the next day. I waited four months to get it back and it was in worse shape than when I sent it in. There were several other issues that didn't exist before the gun was sent to them as well. Savage did make it right with me but they "no longer work on the ML2" after the work they did on my gun. I was also told that "they didn't want to discuss the work that was done on my gun"... Imagine that...
The washer technique sounds like it will help you with making your gun usable. I never tried it on mine. One thing is for sure the gas cutting you see on the plug is matched by identical cutting on the barrel where the plug seats against it. The washers may be successful in stopping the leak but the cut marks are still going to be on the barrel. Unless you have the barrel set back and the sealing surface re-machined true again, or have a new barrel installed. It's just a matter of how you wish to spend your cash to have a hunting rifle. I chose to do it on a Remington/Brux setup from Jeff and forgo dumping the cash into the Savage. There are plenty of people who make them into good guns it's just your preference on where you shell out your dough on a SPML...

Is there any chance a OEM Savage plug barrel such as the early Pacnor 45 conversions could be rethreaded (without cutting the barrel shorter) for a rear sealing plug?

Who makes a good 209 shoulder plug Jeff Hankins makes a good 209 bushing shoulder plug with 3 different bushing choices. I like my .035, I think it is a 9/16x24 thread plug $75 if I'm not mistaken. I'm having him rebarrel my ml2 and am having this plug in it. I have this plug in my apex and am pleased with the performance. Hope this helps.

Rethreading is not necessary. The threads might need to be tapped deeper. The only thing for sure is that a shoulder would need to be cut for the plug to seal on. I have a small shank pacnor that I will make a plug and install it as I have time.

Have 1 "original" condition ML2 and 3 700MLs with bolt nose and savage type plug in original barrels as well as an Omega with original barrel and plug. I don't shoot SML in the "smokers" but plenty hot BH209 for sure. I know about the savage nose seal problems. I use just a dab of copper antiseize on the plugs but really good wrapped with yellow ptfe tape. No problems with cutting. Also use a bit of ptfe on the vent liners too as well as antiseize. I do keep a lookout for any signs of cutting and none so far. 2 Latest SML builds have rear seal plugs and still use the yellow tape. My results, yours may be different. 10
