Last night I was playing with my rifle and the breechplug thing.I have been making different designs by cutting a 3/8" cap screw and working it down.I just tried out a new one by firing just a primer when I noticed something that I hadn't picked up on before.
What I noticed was that after firing the primer, the internal part of the bolt/firing pin was extended out of the rear far enough so that I could put a dime in the slot that you use to take the bolt apart with.All this stuff on the inside is new and clean. I am using the spring the was supplied with the conversion kit.
I was shooting from my bench and I was holding the rifle with my hand just behind the bolt and I could feel the pressure like a gush of wind at the shot.
I quess this just leads to what has been done by Dave and Sabotloader that there has to be a positive force applied to the primer for all of this to seal.

All these reads with no replies must mean that I wasn't clear as to what was happening.
I quess all that I was trying to say that the bolt is not a postive mechanism by not somehow locking into place once it has hit the primer.What was happening to me was the pressure just from a primer was pushing the firingpin/hammer back into the bolt.Enough so that I could have put a dime in the slot.Rem owner know what the slot is,I hope!

You weren't clear as to which rifle you were referring to. I'm glad you realize where you need to begin. And as I said before it's not by using a 209 and a Cabelas half baked conversion. Go for it! Get your lathe hummin'.

I hear ya, I almost had one the other day but there was too many missing parts.My mission has been to find a good used one but it is really hard to find anything in my neck of the woods.
Have you had any experiece with the small bench lathes?

You have to really know what you're looking for. Some are old and worn. The new Chinese ones may have questionable accuracy. If you find that out the hard way then who would buy it from you? You probably should look for an old South Bend 36". But they go for a lot of money unless you hap upon some dead guys widow that doesn't know what it's worth. That sounds underhanded and nothing good would ever come from that. I think your only solution is to mail your rifle off to Denny and be done with it. LOL!! Good luck in your quest.

I ordered my lathe/milling machine.Just one of those teeny ones but I believe that I will be able to do what I need to do with it.I just don't have enough money for the larger ones at this point and I wouldn't be able to get it into my cellar for a month or more.
I think that I will follow your path on the conversion but why did you go with the 32 ACP? I can't find it in my reloading manuals.I hope you don't mind me bugging you for a measurement once in a while.

:)nm which machine did you buy and how much was it? you can cut a plug for a .25 acp which imo is a better choice because your bolt nose will also carry 209's so if you ever want switch back to them in the future you would only have to alter your plug.

Nmaineron, We chose the .32 ACP so that the original Rem 700ML breech plug wrench would work. I figured that if we didn't have to include an additional wrench with the conversion we could keep the cost down. Ideally I wanted to chamber for a .40 S&W that way if you got scared that the small rifle wouldn't work you could simply use a trimmed 10mm case and go large. As it turned out,our small rifle primer works fine. The breechplug is chambered for the brass case meaning the gas expands out to the I.D. of the case and then gets funneled down to the Lehigh vent liner. It will intensify the flame the same way that the expansion chamber on a two-stroke dirt bike makes more power. You just need the flame not the pressure. The other school of thought is to use a small flame channel like Savage does but I think that leads to excessive buildup in the channel where ours has none. Anyway we must be on to something because Remington wants to meet with us to see the design. Who knows maybe a 700ML II??

Wow, that cool! They ought to call it the Mountain Edition!
Dave, my little unit is a 5" x 7" with the attached mill.I paid $549 free shipping.I just can't afford to get what I really want so I am hoping that I didn't waste my cash.If I can make the breech plug and get this little project done along with another I have going with my bike then I will be happy.
