This rifle is nothing extraordinary and is built with affordable parts. What sets it apart from the norm is the ignition system that is used. The rifle is built on a Remington 700 SA center fire action with a .452 Douglas barrel set into a Houge ghillie green overmolded stock. It is not bedded but has aluminum pillars and the barrel is full floated. A Harrells tactical break was installed to tame the recoil of this very light weight rifle and I used Norrells OD green for the bottom metal and bolt and flat dark earth for the action and barrel.  The main reason this rifle was built was to prove a concept of using 209 primers that slide into the end of a custom made bolt. The camming action of the CF bolt allows for a snug primer fit and easy extraction without having to use a lot of force when closing and opening the bolt…and it works exceptionally well.   I made a modified version of Lukes Arrowhead breech plug because the internal breech was already threaded to 5/8x18 and there was not enough barrel shank to cut off and start over. Would have preferred the smaller diameter but this one seems to do just fine. Kash and Meyers and maybe some others have been working to come up with a replacement Remington bolt that uses 209 primers as well and the concept is definitely a good one. The bolt bodies are not particularly hard to make just time consuming and therefore would be relatively expensive to mass produce.  This one belongs to Hillbill and is awaiting a 700 SA Those who like the idea of a “switch barrel” set up will find this system to be a workable alternative. This system has been good so far but I don’t have enough experience with it yet get all “slobbering at the mouth” about it yet :-). Yeah, Josh, I’m a knuckle dragger too…shiny object…shiny object…. 100 yard range and shooting bench...hard to beat a good solid concrete bench  Haven't had a chance to shoot this particular build yet but the Douglass barrel has shot at around an inch when used with other ignition systems. I have tested this 209 bolt system for function and safety but not for accuracy yet. The cam works very good to seat a tight primer and to extract the primer Best, Mike |

Very nice bolt. I like the two colors used on the metal. Is that bench running left or did you hold the camera sideways?  |

45Omega, Story of my life...about 5 degrees BTDC
Russ, No shiny finish...give me a sand blaster and Norrells...life is too short to polish to a mirror finish..
Like staring at checkered wallpaper :-)

I was wondering when you were going to put up pictures? excellent work, especially from scratch..
In case you gents don't know it Mike is a pretty sharp guy, keeps his tools sharp too.
anyone have a SA 700 they want to sell for cheap? as you can see Im in need..

Airborne,
Its funny that you posted this, I have had the same idea to modify an existing SA bolt to accept a 209 primer, then shorten the firing pin. Matter a fact I have a SA coming right now and the cutters ready to make the mod. Looks good!

Nice looking work. How much primer is left to go into the plug? Looks similar to Savage bolt head. Was curious if this left more primer to go into the plug than a savage does? Good work again.

Very cool love the 209 bolt face.
Knight rifle mountaineer bar primer have used similar ideal using primer end to end crush fit seal with proper flame channel size works flawlessly.
Great workmanship and build.

Very nice work Mike, even more impressive that you do it all on manual equipment. I know that Bill's new build is in good hands and I have no doubts that bolt will perform very well with the new plug. Did that rifle have a knight plug in it before this experiment?

Great set-up Mike! Mike sitting in his shop, is like a 3-D printer with its own brain. If you can think it...Mike can make it. Gotta love the ingenuity on the board! I need one of those concrete benches in my yard. oh ya...MONGO LIKE SHINY THINGS! |

Typical171, I first thought about modifying a standard bolt but it seemed like there would be more work involved than just starting from scratch. The body is not difficult to build but there is a distinct process that must be followed to get the timing right.
Ohioguy, The bolt nose is about the same as Hunters bolt nose and encloses most of the primer. I have not seen any bulges in the primers but I have only shot 70 grains of H4198 with 275 BE's. Not real familiar with the savage types.
Bestill, I intend to try some different PFC diameters and lengths from primer to bushing when I have time. Right now the plug is just a bit shorter than Lukes but the configuration is nearly the same. Works pretty good as is but will try some different things just to see.
Meyers, The barrel has been the recipient of several different primer systems over its life due to my crazy need to tinker. There are not many shots on the barrel but it has been useful for experimentation. Douglas makes a good barrel.
Bill, not too sharp, just lucky.
Josh, I admit it...not right...in da head :-) The concrete bench is a product of my brothers bitching about being able to see his heartbeat when shooting. Myself and two other guys built this in a couple of days just so bro Larry would shut up. Does work nice though.
Thanks for the compliments but what I would really like to see is some more of you machine tinkering nuts get busy and see how far we can take this smokeless muzzle loading :-)

Rich,
Your work is as good as any I have seen ...we are all tinkerers!
Paul was getting married...poor fellow...nice wedding but truth known me and Larry both would have rather been somewhere else :-)
You would not have believed how much Larry complained about that old wooden bench :-)
Thanks
Mike

Beautiful work, Mike. You're custom bolt looks just like my Savage CF with Luke's 209 boltnose. My primers were sticky until I put a headspace bushing in. I assume you already solved that problem.

nice day here today so I got out to shoot this build. After 3 shots it settled down and held a deer group about an inch. Was using fullformed 275 BE's with 70 grains of H4198 no wad. The function of this system is nice and will make a very good hunting rig. The velocity was around 2750 fps on average. The most notable thing was the recoil reduction with the muzzle break...was not at all unpleasant to shoot. Love or hate muzzle breaks...they work. Someone out there needs to produce these bolts at an affordable price for the masses!  First smart remark about the white hair on your's truly and I'll send my pack of "weenie wolves" after you....:-) |

Glad to hear everything is good and the brakes are becoming more common in recent month as. Everyone is tired of getting beat on I think. As Mike said these bolts will be great for guys that want to go the cf route. We should have the first run of 20 done in a week or so and at the rate I sold the majority of them, I see no reason to not order 100 the next time around. Thanks for the report snowy! |

About the hair, my wife would say that is just experienced silver. Keep us posted on the shooting.

At least you have hair Mike, it either turns gray or turns loose.
If we did a poll I would guess there would be more gray heads than solid colors on this board?

It's every bit as important to have one of them there green jackets as one of them bolts. I have one, guess I need the other now.

Ed, I try to bore the primer pockets to where the primers just touch in the bottom when the bolt is closed. Hard to get that dimension right. The primer pockets are tight but have not had any sticking problems yet. I try to polish the pocket smooth and that helps.
Keith,
Those old field jacket liners and the light weight poncho liners are one of the few pieces of equipment that the Army got right,IMO.

Those were good liners, my first one was wool as I recall before the replacement liner. Keep shooting and keep posting.
