breechplug mod

[dave d.]

:)guy's many of you know of my remington 700 .45 that uses acp cases primed with federal 215 large rifle primers.anyway i have grown very fond of these primers as they offer excellent ignition and they are very clean and there is no blowback as a matter of fact the inside of the case when fired comes out clean.know this also has to do with breechplug design and headspacing which i think i have down pat.with a new project coming very soon after about 8 months i got a itch so off to pa machine today to scratch that itch.here is a pic of a encore style plug that uses acp cases primed with lrm's.






headspacing is within a couple thousandths.the encore with 209's was filthy after around 20 shots.my hope in what i've learned with the remington is it will eliminate all mess.but i will not know untill next saturday.we will see .

Nicely done.

Dave, are you going to use these plugs with smokeless in the stock BP Encore barrels?

[ET]

Look forward to how well you scratched that itch with forth coming results.

And the beat goes on for different ideas.

nicely done Dave, looking foward to the new project.

[Dave W]

An early tease eh. ;D I'm sure you will have it driving tacks if not already.

[dave d.]

:)guys thank's alot.right now this is just a test for future projects.

It came out really nice, it should keep the blow by to a minimum

Dave, are you using a vent liner in that plug?

[dave d.]

:)thank's guys.ken yes it has a vent liner.

[screwbolts]

Thanks Dave for the reply:-)

It looks to me as you have trued the interior of the case head?

I have thought of doing the same thing using a LEE Case Holder in the chuck of the lathe,( the case holder LEE makes to turn the case with there Case length trimmer) then making a truing cut to each Case head, also slightly to the tapered sides as shown in your photo to thin them.

I have thought of doing this for my Roller, The roller action actually gets tighter as the hammer reaches its forward most position. it would tighten up that .002 clearance.

:)ken yes i did clean the bottoms.i like them all to be very close.

[dave d.]

:)guys i did another simple mod to my plug.i was hoping for alittle tighter fit because when i opened the gun the cases would almost fall out.so my first idea was to try and size the case down alittle and that didn't work.so i turned to my bud edge for advice and sure enough the jedi master said why not a oring?thankyou bud it works but i could not get the right size o-ring so i had to make a shim to take up the difference.here is a pic of the temporary fix till i get the right size ring.

[jims]

That looks like a well thought out solution.

[dave d.]

:)thanks jim.here is a few pics of fired cases and breechplug.there would have been zero carbon anywhere if one of my cases that was short didn't misfire.i knew i shouldn't have tried it but.




my encore is 209 free and blowback free .
