A Covid fairy tale

[oldstarfire]

I was in my shop a while ago, and in a quiet moment (had my hearing aids on) I heard a plaintive cry,
It came from a 2 inch round bar of steel~ The voice said " I used to be a German target rifle. but was turned into a axle shaft by a wicked Liberal Jas...witch. If you kiss me with an end mill, I will try to regain my old form." What else could I do?
To be serious......
Some of you may remember my feeble attempts at rifle builds. I have been cooped up (no, not Mexican beer disease) so to pass the time, I decided to have a go at another rifle.
Started with a 2 inch round and after some milling..

The groove was there already.
More to follow.......

Drilled and tapped a barrel hole.

[oldstarfire]

do you have blueprints?

No, going by a drawing in a DeHaas book - Single shot rifles and actions

 

[marshall]

do you have blueprints?

Blue prints, who the hell does that?????? It looks like a neat comp in waiting

 

[375 RUM]

can you share and post drawings please?

 

[kayceel]

What barrel do you intend to use?

 

[oldstarfire]

Next installment:
Opening up the bottom a bit

Cutting a through hole

Do not have drawings. Get a copy of De Haas book.

Dont have a barrel, will be center-fire, maybe .25 ish

 

[oldstarfire]

Trying to square out the thru hole.
Endmill did not like the hang out

After some...um....bad words

 

[oldstarfire]

With some comb and brush work.......and some "product".....

Starting to look like a something?

 

[dead meat]

Getting the proper shape slowly.

 

[oldstarfire]

Did a bit more. I realized that the part as in last pic was too shallow.

I welded 1/2 inch extensions on the bottom, and trimmed the welds.

Sprayed with ink to show up better.
Now on to the breech block.

 

[littlehughey]

Is this going to be a falling block design?

 

[oldstarfire]

Is this going to be a falling block design?

Yes, breech block slides up/down at a 12 degree angle.

 

[oldstarfire]

So here is the beginning of the breech block

Was asked about barrel - Thinking of 22 Hornet, or 17 Hornet, or maybe a 38spl/25 "wildcat"?
So am wondering what is out there -suggestions?

I am following along with interest. Regarding what to chamber it in, Ruger and Winchester apparently came up with the 256 Win Mag back in 1961. It was a 357 mag case necked down to 25. My Hornady manual lists 1900-2400 fps with a 60gr bullet, 1600-2100 with a 75gr bullet and 1300 to 1800 with an 87 grain bullet. This is with an 8-1/2" barrel. This info is from Hornady sixth edition. The manual says they could get almost 600fps more from a rifle (Marlin 62). Just a thought.
