I wrote this article many years ago and my friend Juan Pozzi ask me to post it here. It was writen in Spanish and I translate it using Internet so I beg your pardon for my English.
I made a Scout rifle as an option for left handed shooters. In those years lefthand rifles were difficult to get and very costly in Argentina.

My Scout Rifle.
Right handed bolt rifles are very difficult to cycle left-handed if it have optic-sight, as the sight and mount interferes. You have to lower the rifle to reload, and this makes a second shot too slow.
If you want to use a standard Mauser action, one option is to have some stockmaker make a low throat or thumbhole stock that allow to drive the bolt with the right hand wile you support the rifle with your left hand. This is not much convenient as the center of mass is too far to the front. We can leave the rifle without optical. Obviously this diminishes the efficiency of the weapon, reducing its precision so I chose the Scout option.
The Scout rifle is "the creature" of Jeff Cooper. Copper is a living myth in the circles of combat shooting and he is considered to be one of the most important gurus. Even thou his ideas are usually a little radical, he really knows what guns and/or technique really works.
The scout is a soldier who, alone or in groups of not more than three, crosses the enemy lines looking for information. He must avoid the direct combat, so he do not need great volume of fire but he must be able to hit a target from unknown distance. The sniper's rifle does not works for this task as it is too heavy and the scope have too much power for short distance engages. Incidentally the English scouts on service in the Pacific during the Second World War used Enfield bolt action rifles.
According to Cooper the scout rifle must measure a meter and weight up to 3 kg. The .308 Win. is the classic cartridge for Scouts rifles but there are some Super-Scouts in .350 Rem. Mag and .350/360 Mag. (A Wildcat) for the African big game hunting.
The scout rifle uses a intermediate focal distance scopes, usually 2x to 3x (handgun scope), so it can be mounted in front of the action. This scope avoids "to get into the scope" as it do not blocks the vision and it is possible to shoot with both eyes open. In addition, the forward position of the scope facilitates the load and transport of the rifle.
A few years ago I assembled one of these rifles. I always want one rifle for hunting “everything" and my conclusion war that it have to be a .375 H and H Mag. with a 3x scope.

This is the first axis deer I killed with it.

In 1991 I bought a military carbine Mauser I found a very good price for the project as I already had a Leupold M8-2 scope. Obviously it had to be a .375 H and H to fit in my concept of “a rifle for everything†from elephant with certain care down to general big game hunting.
The first step was to lengthen the magazine to accept the long magnum cartridges. I chose to lengthen it backward against another alternative of doing it forward. I do not like the latter, even thou it is used by several important makers, as implies weakening the lower lung.
I chose to place the back base on the front ring of the action and the forward base on a turret welded to the tube. This one serves also as the second shoulder of the barreled action in the stock. To avoid accuracy problems I glassbeded the action up to the front of the turret and leave the rest of the barrel freefloated.
If you decide to leave the original barrel, you can bolt the front base to the rear sight or you can mount the whole scope with an assembly similar to the one that makes B-Square of the USA.
The field of view of the Leupold 2x is about the same of one of 6x42 scope.
Till now they all are advantages. The serious problem of the scout rifle for hunting in Argentina is when you try to use it in low light environments as moon light hunting. The sum of low power, long focal distance and thin cross hair make it very difficult to hit with it.
Some one can criticizes that we use an action that is too long for a classic Scout. Till now all the Scout Rifles were made with short actions like the old Remington 600. Considering the cartridge, we can say that, in proportion, the mechanism is short, provided that this action is used for cartridges like the .30-06 or the .300. Win. Mag..
My scout can be called a Super-Scouts or an African Scout. Even thou it is out of the standard with its 1,20 m length and 3,9 kg, I till consider it a Scout Rifle in proportion of the cartridge. Anyhow, I can say to my favor that my intention was not to make a Scout Rifle but to get a rifle that I can use left-handed.
The barrel of 24 inches was made in Argentina and though I had a chamber problem when I received it, now it is very accurate.
Initially I used the military stock but due to its light weight, the recoil was so much that I can only shoot 10 to 12 accurate bullets. The it hurts so much that I can not shoot anymore.
The new stock was a copy of a Rigby .416 of 1912 (the year in which .375 H and H Mag. was introduced), except for a longer forestock. This design helps to the recoil very well. In addition, I aded a Skeet rubber pad to increase the surface of support on the shoulder and to distribute the force of the recoil. This stock turned out to be heavier than I wanted because I chose a piece from the central part of the trunk.
The balance of the rifle stayed almost like I wanted it, on the front screw of the mechanism, the importance of this is that a balanced gun seems to be lighter and is easier to use.
In short, this is a practical alternative for us (left-handed), obviously the best is to have a left-hand bolt rifle.

Muchos Gracias Martin,

Usted Anglais is much better than most of our Espanol.

You have built a very useful rifle.

Left handed shooters of the world, unite!

LD

Martin the article and general idea are excellent ,only an expert like you can prepare a rifle like this ,ill pass the word at the south american forum .Juan

MARTIN: You have a PM, in Private message zone, Thanks!!!

Martín: out of curiosity, which was the barrel length and what ammo do you shoot in your Scout?.

nainital,
Barrel was 24"
Made most reloads using light bullets, 200gn Sierra and 220gn Hornady. Both bullets was designed for low speed but works OK at 2.700 fps. (68-69 gn of A27).
Thanks
Martin
