Got the mag box cut off the bottom metal and shaped as intended. I thought I was going to have to weld some of the sling hole but when I filed the bow to the desired shape it dissapared so that is one thing to tick off the list and then it was simple matter to inlet it into the stock. I fitted the altered trigger from my 7x57 so I could comfirm it was all going to work untill I can get the two into one welded for this rifle. I still have to file the slot in the trigger bow base to allow the fingerpiece to travel to the rear further because of the change in its position.

A little more got done after lunch with the tang re-shaped



The waist filed into the trigger bow



and with the t/g inlet down to depth, I could then refine the wrist shape and start to get some slimness into it. I wont go any further untill the barrel is inlet and I can shape the forestock and then it will be a simple case of joining the forestock to the wrist in a nice continuous radiused easy to handle shape

I decided to changes thing a little as I had intended to lengthen the trigger when the two halves were welded back together as the bottom line of the stock is .185 deeper than ordinarily it would be with the standard bottom metal so I could have the mag capacity in the blind mag without compromising the strength of the remaining wood. There is about 3/16 left but this was making the wrist a little beefier than I like. It was near 6 inches in cicumference which is way to big for the style of rifle I envisage. The answer was to raise the trigger bow up so the trigger length would be standard and the wrist could be made much smaller and to do that I thought I would do the same as they do when an extended magazine is made. It can be subtle like this 350 Rigby mag which has been a real inspiration in many ways (credit to XAUSA for this one)

or this Hartmann & Weiss

or over the top like this one

I was thinking of the subtle end of the spectrum and set the trigger bow in an extra .185 which leaves the trigger length the same length and will preserves the stockwood thickness under the mag well.
Have it roughed into shape and was able to reduce the wrist circumference to 5 5/16 but should get down to under 5 inches when the finish shaping is done which will have to wait untill the barrel gets installed and the forestock shaped. This is how it sits for now.


Incidentally, the drop box magazine has been made by cutting the standard box and welding it further down the trigger bow face which may entail extending the top edges if too much drop is required. (If the available funds dont run to one of the expensive off the shelf units.)

I got the barrel band done this morning. Threaded to sling stud shaft that I filed down in the drill press the other day and shortened the band nut so it would be a nice compact unit. Because I couldnt thread right up to the shoulder I countersunk the nut enough to get a good mating surface. This should be stronger than any soldered joint with about 4 threads to hold it in to the band nut.

Next was a trip through to the GS to drop off the parts for his attention.
He will shorten the 6.5x55 barrel enough so he can rechamber for the 6.5x57 with his match reamer then rethread for my action. He is going to reprofile the chamber end out for a few inches to give it a more pleasing appearance as well.
Change the bolt handle, D&T for the Tally bases and front sight, and weld up the trigger pieces and the lock screw hole on the TG.
It could be a while till he gets it done so I will have to controll the impaitence till I get his call.
I called into see a friend and picked up a partial precarve mannlicher stock and will finish it for a G33-40 with a number of changes. The biggest being the grip end being changed to a Prince of Wales grip and the cheekpiece and butt end will get a major reshape. Incidenty this B/A is military configuration and will stay that way.

Just question; why 6,5x57 instead of 6,5x55 ?

A couple of reasons with the main one being that I wanted it. The 6.5x57 was more in tune with my preference for the x57 case and would be a good companion for my 7x57. Cases were another consideration as I can make cases from any of the x57 or 06 based cases even though I got a bag of headstamped 6.5x57 cases. Getting a set of Dies for almost givaway price didn't hurt its desirability either.
In the end, when it came down to it, I saw this rifle as being a bit special for me given that the action and blank came from friends so it deserved something a little out of the ordinary run of cartridges to compliment it and for the type of hunting I do now the 6.5x57 is right up there in the multipurpose capability. I know the x55 would do the same thing but then so would a host of other cartridges which I also discounted as I have a bit of a fixation on the x57 case with it being the grandaddy of all the modern cartridges and about perfect for a multitude of bore sizes and bullet weights while the 6.5x55 is a bit of an orphan with nothing outside of its primary designation ever having been done with it.

Thanks for yours answer, Von Gruff. I have one pre-WWII Mannlicher Schönauer in 6,5x57 so I know that caliber quite well. It seems that here in Europe 6,5x55 has come so popular that 6,5x57 is now kind of marginal caliber. Only S&B and RWS make factory ammo for it.

Home from the gunsmith with the bits done that needed to be done so I can finish the stockwork. It will go back afterward for the polish and blue and the cartridge engraved on the barrel. Very pleased with it and couldn;t help but to sit it into the wood as far as no barrel channel would allow just to see it in one piece---sort of.

It was a very heavy frost this morning and really a bit cold to be in the unheated shed but having waited to get the B/A back I was anxious to get the barrel inlet done so after a quick breakfast I made a start.
A preliminary track was made so I could sit the B/A in place and mark the lines in

And half the barrel dia marked n the end to get the depth of the inlet at this point


So with a bit of smoke to guide me I made a start. Having said that this piece of wood has fiddleback so I couldn't use a chisel accross the grain and waves along the chanel so I couldn't use gouges or even my barrel end scrapers along the channel without it chipping the grain out (you can see this in the previous two pics) so it was a case of 60 grip emery round various round dowels to remove the wood without damage to the finish lines I neede to keep sharp.

It took 6 hours to get it done but eventually it all settled into place

After that I got the piece of horn doweled into place and cramped up for the night.

Got the horn tip inlet this morning and have run the forend through the bandsaw so it is ready for the shaping process now. This was a piece of horn I didn't think I would be able to use because of the slight curve and the end of the interior hollow of the horn which made it necessary to set it to one side that in itself threatened the runout through the curve. The interior hole was larger than the barrel diameters I had been using on other rifles but this one is just slightly heavier at the point where it meets the tip and I also shortened the wood part by another 1/4 inch so that with carefull placement it was able to be used.

Have finished for the day and will not be ble to get back to it for a few days now but quite pleased with how it has shaped up. It has fulfilled the original design concept I had and at 6lb 9oz with the Talley aperture sight installed but without ammo it is going to be a nice fast handling hill rifle. The balance pount is a 1/4 in behind the front action screw so it will be very pointable with a very quick mount. The stock wood has more than lived up to what it promised in the blank with really nice colours with the marble cake and fiddleback really showing through now.

The last few days have seen the stock refined and reshaped a couple of times. It has been sanded through 100, 150, 220, and 360 grits then wetted and 360 sanded twice and the same with 600 grit paper so it is ready for the finish now and that will start with about 4-5 coats of 75/25 turps/spar varnish and then a couple of 50/50 coats (sanded with 600grit paper between coats) to seal the surface from the inside. The finish will be straight tung oil for as many coats as it takes to get it right then a rub off with rottenstone and it should be good to go.

I am waiting for a new extended left side flag safety to arrive so all the metalwork can go back to the GS fitting, getting the cartridge engraved on the barrel and the blueing done. Fortunately we are in mid winter and while I look forward to having it completed, the weather is not condusive to extended testing of loads etc. I will probably get the brass fireformed and leave the load testing for better conditions, besides which the high country I like to hunt is not excessible till about november anyway so I have time to find a load it likes with a 139gn privi partisan and the 120gn TTSX. QL is telling me I can run the 139gn bullet to 2800fps (H4350) and the 120gn to 2950fps (H414) with a 57k psi redline so ther is plenty of performance to tap into.

I have the rifle at a sgate where I can get some pics with the intention of showing just how nice this piece of wood really is. Still in the white and will be till the extended flag safety and the Talley qd rings arrive then it can go back to the GS for polish and blue.By then the canvas sling on order from South Africa should be here and the rifle will be ready for some amunition trials.
It is near mid winter here and so these pics had to be taken on the porch with the weak sunlight offering little in the way of good light (along with my old cell ph). Whern it is all finished I will get a friend with a decent camera to try for better pics but in the meantime this is what I can post.

I got the left side extended flag safety and the talley qd rings in the mail this morning so mounted the scope to see how it looked. I had intended to fit a m8 6x Leupold but there was none available here so I bought a 3-9 Nikon instead. I have a few other Nikons and like them a lot and at just 13 oz the complete package weighs in at 7 1/2 lb so still a portable hill rifle. Mostly it will be hunted with the aperture installed and the scope in a carry bag. I can cycle the bolt with the lens covers on with good clearance, so getting the bolt fitted the way I did has worked a treat. It still has the oberndorf look I wanted but allows for the lowest Talley rings and no scollop out of the bolt handle to ugly things up..

At the moment the metalwork is away at the gunsmiths for blueing so expect it back in a couple of weeks.

Great lines and really nice work.

From the early photos I thought that your XXX Claro blank might be too flashy for this project, but it works, and it works very well.

How much does your trim little rifle weigh?

With the Tally peep sight installed it is 6lb 9oz and 7 1/2 lb with the scope on board


I hadn't been sure or the exact variety of walnut but you mentioning Claro made me remember this piece from this link. http://www.doublegunshop.com/phiatt.htm
Claro walnut is American black walnut grown in the West. Claro grows faster and generally comes from larger trees than its Eastern cousin. This is an advantage as the better wood generally is added on after a tree reaches three feet in diameter. Larger trees also yield wood with thicker feathers which means less "one-sided" gunstocks. Claro is also more colorful than its Eastern cousin with more brilliant reds/yellows/greens/purples. Sometimes it is less dense than its eastern cousin. Sometimes it is MORE dense than its Eastern cousin. Again, judge each piece individually. As a general rule, seedling trees are more dense than their grafted counterparts. English walnut is often grafted upon Claro rootstock and the resulting gunstocks that exhibit the best properties of each are amongst the most magnificent of all gunstocks.

Beautiful piece of timber there VG!
Done a marvellous job to date, lucky to fit the piece of horn on weren't you - only by a whisker.
Will be a cracker when you take to the hills, going after reds this time or tahr?

Fantastic work, very impressive looking rifle. Are you going to checker it ? Great caliber as well.
