Attaching iron sights to a barrel

An expert opinion please..

What are the chances of undue stress release (and bore misalignment) on a rifle barrel if a sweating process with normal lead, not silver solder, is used to fix a rear sight?
 
It depends on the sight and whether it was designed to be soldered on. After all, the old military Mausers had the rear sights soldered in place, and shoot point on even 70 years later, but those sights had plenty of holding area. They also had a small hole drilled into the barrel for an alignment screw to make sure they were mounted in the right place.

If the sight is intended as a screw-on sight, drill and tap the barrel before soldering it on, then attach it with screws after soldering.
 
Scorch is correct. I will add that the heat for sweating on a sight is not going to hurt the barrel steel. The HiForce 44 Solder from Brownells is excellent for the purpose. It melts and flows at 475 F.

Many thanks, your advice is greatly appreciated. I needed third party opinion before giving the go ahead.

An excellent job was done today to my 70 year old Lee Enfield and it shoots like a dream with modern locally manufactured soft point ammunition. In fact it is going to be next season's kudu, warthog and impala getter with these sights.
 
Africa

Sir;
In Africa I'm sure you've heard of the 9.3X62 and 9.3X64! I've built four of them and really love the 9.3 caliber! Good hunting to you.

Dear Harry B,

What excellent calibres you mention there! And what a man to have in fact built them! I am a mere farm boy/shooter/ex military airplane driver, and the artistry and sheer mechanical prowess of gunsmiths have me in awe each time I watch people like you at work. Co-incidently, I have just befriended a gunsmith and although I have grown up with rifles in my bedroom and understand them, I learn many things from him each day.

Sadly, in my part of Africa which was a British colony, and what with the Brits not having been overly in love with the Germans very few of the many excellent German calibres came our way, except for the 7x57 of course which were used rather successfully by my forbears against the "ungodly english" (the lower case "e" was in fact intended in those days!)

I hunted in South West Africa (now Namibia) with a borrowed 8x68 Mauser, a very potent cartridge, and just for fun had some shots with the 9,3 x 64. I owned a Sako Hunter in .375 H&H Magnum at the time, which, by the way is way overpowered unless you go for elephant. I was equally impressed by the 9,3 and would have loved to own and shoot one, just for having it!

Like the people of (Southern and Western) North America, my tribe, the Boers, have guns in our blood. It is as much a culture thing as a firm belief that a man must have a .22 Long Rifle and some .30 or 7mm calibre and a shotgun and a revolver. Obviously one then finds "reasons" for a 6mm a 6,5 and an 8 and a .375, and who can go without a .270W for that yearly few Blesbok in the Free State province, and then a Winchester 1200 Defender for the bushpig, our only wild boar (not warthog) which you can only hunt on moonlit nights and they do not like being wounded from 15 yds, so another quick big hole (in its head at 5yds) calls for that short barrel and good slugs.

Oh, by the way, I want to build a .35 Whelen as I do not have the .375 anymore, and I am going to do a wildcat 6,5x 57 via the .303 British.

May talk to you again if you do not mind, about my ideas for the 6,5 - no pronounced shoulder, a little like the 300 H&H. I want to do a ladies rifle that can take both Kudu in the dense bush (160gr) as well as Springbok in the open (120/140156gr)

Kind regards
 
May talk to you again if you do not mind, about my ideas for the 6,5 - no pronounced shoulder, a little like the 300 H&H.

I too have wonderments along those lines. What about someting like the .240 Weatherby Magnum with H&H shoulders chambered in 6.5? Case volume would be a tad limited, but modern powders should come a long ways to bring back up the speed. And, standard long length receivers should still be used. The 257 WM would be a little long with the addition of useful 6.5 bullets. The 264 Win Mag case, as a parent case, may have promise, but has a huge powder collumn and may still be quite harsh.
 
My thoughts for using the .303 British are the following, and are purely because of local situation:

1. We have large numbers of excellent Lee Enfield actions going to waste and one can clean them up fair enough to make a fair anough looking working gun.
2. Cases are in abundance.
3. The H&H neck makes for good pressure transmission and so headspacing shall be on the rim.
4. I do NOT want more than about 2450-2500 ft/sec muzzle velocity with the 160gr bullet, and 2 900 with 120gr is OK.

I can see your thinking about the .240 Weatherby, though. The calibre (the brand, really) was never at all popular in South Africa, so I do not have a case to look at.
 
I don't think I've seen that case here either. But I do look at my reloading manuals and Ctgs Of The World book and sometimes my mind wanders about such things.

I am way behind the time, but just may renew an oldie:

The .303/25, sometimes known as the .25/303 is a wildcat centrefire rifle cartridge, based on the .303 British, necked down to fire a .257 projectile, originating in Australia in the 1940s as a cartridge for sporterised rifles, particularly on the Lee Enfield action, similar versions also appeared in Canada around the same time[3].

The .303/25 was very popular for a number of reasons, one being that the .25 caliber was better suited to small game than the .303, the rifles were cheap and plentiful and in New South Wales ownership of military cartridges was severely restricted. Several versions existed but most were simply necked down and remained full length. Although Lee Enfields were the most common, conversion of other rifles mostly suited to rimmed cartridges such as P14 Enfield, Martini Enfield, 1885 and 1895 Winchesters were often seen, as well as 98 and 96 Mausers[4].

Loaded ammunition and brass was produced by the Super Cartridge Comany, Riverbrand, ICI and Sportco, some using new Boxer primed cases, others using military Berdan primed cases. Cases can be formed simply by necking down .303 British brass available from Remington, Federal, Winchester, Sellier & Bellot and others. Reloading dies are made

Sir;
Good to hear from you!
I've got several No. 4 SMLE rifles and they are a favorite with me.
Hope you are having a good hunt and doing some shooting.
Yes, I love the 9.3s and the 416s - why? I don't know as there are no buff in Ohio! I guess I'm just smitten with Capsticks writings and Africa!
I do not like the Weatherby calibers; it seems like they just have to do everybody one better and I don't like that.
Order the A-Square shoooters manual - it will be a blessing to you. They cover the "big boys" in the African calibers.
My 9.3s and the 416 Taylor are very light in recoil and I barreled a Savage 110 with an Adams and Bennet 416 Taylor barrel and even with a plastc stock it would make a DGR rifle and recover O.K.
I'm 73 now, but I still fool around for myself quite a bit - but Africa - too Old!

Some hunting

Mr Bonar, Sir,

Took my son out and he got a warthog and I an impala.

The warthog in my mind is this part of the world's best meat. I further believe that the mustard seed was planted on this planet because warthog roam it...

Tonight I had the neck of the impala ram in an oval pan with a good sealing lid in the oven. Olive oil and Worceshire sauce and black pepper and salt. Some grated orange peel over it, and 3 hours at 180 degree C, turned once.

One is supposed to go through life with a humble disposition, I know, but still I wish to believe that there is no restaurant that can match what came onto the table.

We have an equally humble red wine here, not even from the Stellenbosch region, a Shiraz- a man's wine. Some rough edges to the final, lingering on the palate, but it never leaves one with any doubt that you shall drink it again. Need I say more?

An honour to read you kind postings and an admiration for your approach to guns and the finer knowledge of their workings that I believe myself to be still a learner of.
 
Wildebees - that recipe is nearly a duplicate many Southern-Americans follow for a boned-out venison neck roast, we also drape a couple slices bacon over the roast, and use a little higher heat (250f.) for shorter time with onion, garlic and carrots in the pan. Only higher-end restaurants serve wild game here and few of them prepare as well as accomplished home wild-game chefs.
 
venison recipes

Mr. 45Marlin,

Thanks! I did not have the bacon so I used quite a bit of olive oil, and the garlic and onion obviously add to the finesse!

Raw, slightly cured in pepper corns springbok or impala rump steak, sliced very thin a la Italian carpaccio on olive oil is a very good protein builder with no cholestrol - you can overdue it and only want more the next day. Yes, I am a carnivore; what can I do..

I want a Marlin lever action 45 or .44 Magnum, in fact I need it.
