I pulled apart a military Borchardt action yesterday that I am working on to make a sporting rifle out of. I was surprised to see the breech-block is from a creedmoor rifle and has be lightened by cutting out the back sides of the block. It's also serial numbered. I'm too lazy to pull one from another rifle so does anyone have a picture or a link to a normal block?

Hello Michael, It's not a brilliant picture but you can see one I made some time ago. It wasn't finished at the time but it really isn't that different in shape. Only the top contours of Breech block i.e. the rounding off of the firing pin housing and the groove for the cartridge have to be completed. I do have an engineering drawing that I can scan and send to you if you wish. see:- Other bit and pieces of my home made Borchardt can be seen here:- http://s89.photobucket.com/albums/k206/Rifleman_01/Ignore the finished Borchardt, that belongs to one of my internet friends who I was advising about rebuilding, and also the countryside pictures which are of a local Red Grouse Moorland. Harry. P.S. I'm a terrible photographer.

Michael, If you still need one stop by, grab mime and take it to strip down and look it over.

Thanks Mike I have one I can pull apart but now that 1878 has posted a link I don't need to.
Can anyone name all the parts that were modified to reach the 10 pound limit on the Borchardt-Creedmoor?
I'll start with the stock bolt which was shorter than standard and hollow.

I'm not sure why I'm spending so much time cleaning the action up when I have not finished this project. Too many projects, we all have them

Too many projects, we all have them Michael my Email friend, You have had that project ongoing for several years, I also seem to remember you attempting to sell it on some time ago. I would be interested to know whether the Military action you are working on has the same serial number as that on the Long Range Breech Block. Would you be willing to post the serial numbers of both parts. Having studied the last years of the Sharps factory, I have a couple of theories regarding the production of the Model 1878 Borchardt. The numbers may help me sort them out. Regards, Harry

O/K, I'll have a go, lol. The previously mentioned Stock Bolt, the removal of considerable metal from the Breech Block, (as illustrated in your earlier picture), the lower front end of the action had a lot of metal removed internally where the lever spring is situated. The side panels of the action were also a lightening objective, as the wood or composite side panels that were inserted were much lighter. The Millitary sight was also removed, so just the special Long Range sights were fitted. The Ramrod/cleaning rod was omitted. The Web between the action tangs that the stock bolt is attached to the receiver was mostly machined away leaving just a threaded spigot to hold the stock bolt, and finally the additional machining of the contours of the front of the receiver on top and underneath also took away weight. That's about as much as my alcohol befuddled brain can manage at the moment. lol. Harry.

Other project got in the way, I was trying to trade the oct-toped for a commercial round top.
The action which is a military is No. 7374 and block is No. 342. The breech-block is bushed and the firing pin is a small diameter. Most likley does years ago, someones project that was never finished.

Are you going to mill the reciever walls and do a wood inlay like the one that John W. did years ago?
