So you might have some different experience, your arguments however, are not convincing.
BTW it is not only my experience, but any serious Mauser collector is aware of the lousy Spanish steel ( is it the steel or the heat treatment? doesn't matter in the least ) used in the production of those guns.
Another BTW, just checked my world map and it seems Mexico didn't change its location, therefore didn't move to South America.
Believe what you want.
BTW, I'm interested in how did you find your Spanish M43 Mauser had soft steel? Did it wear out while you were using it?
I have owned and shot a Spanish La Coruna Mauser since about 1995 and shoot it often with full power Yugo and Turkish Military 8mm ammo that is on the very hot side and it is still as good as when I first got it.
I also know of a buddy who had one re-barreled to .270 Win and has been using it like that for about 20 years at least without issue. Sporting .270 Win ammo which is all he shoots in it is a 65,000 psi SAAMI spec cartridge.
Why are the FR-8 7.62mm/.308 Win rifles in such high demand if the steel in them is so crappy, never ever heard of FR-8 owners complaining about their rifles which is hard to understand as a very large percentage of them are just later 7.62mm rebarreled and slightly modified M43 Spanish Mausers and the factory .308 Win ammo shot regularly in them is a 62,000 psi cartridge too.
I have never seen or read a reliable account from a owner of a M43/M44 or FR-8 Spanish Mauser having a defective or soft steel action. I have heard the opposite but never seen this mysterious soft steel.
Per Wikipedia -
Toledo steel, known historically as unusually hard, is from Toledo, Spain, which has been a traditional sword-making, steel-working center since about 500 BC, and came to the attention of Rome when used by Hannibal in the Punic Wars. Soon, it became a standard source of weaponry for Roman legions.
Toledo steel was famed for its very high quality alloy, whereas Damascus steel, a competitor from the Middle Ages onward, was famed for a specific metal-working technique.
How about these other owners and users of Spanish M43 rifles arguments from other forums (US based ones) when asked by newbies about if their Spanish M43 Mauser having the so called soft steel syndrome -
"I have the "M44" (as many collectors call it), the Spanish Airforce issued M43. It has a different front sight and a few other details different than the regular Army M43. Oddly, my M44 and FR8 both have turned-down bolt handles - this was normally done on the Spanish sniper rifles, but mine don't have the sniper scope bases.
Some folks wrongly accuse these rifles of being made of inferior steel, but that is a myth - they are as strong and robust as any M98-type Mausers."
"Andy, a few years ago, the Spanish Mausers were very common. Now the imported numbers have dried up. I had a fair number of the M1943 Spanish Mausers and had no problems with them. I have read reports that the Spanish used too soft steel, but have never seen signs of this. I shot milsurp ammo and also reloaded for those rifles, keeping pressures in the same range as milsurp ammo. The rifles did not show signs of over pressure of any sort. Given two rifles of equal wear, the Spanish 1943 is every bit as good as are the German K98k rifles.
The Spanish M1916 carbines that were rechambered for 7.62x51mmNATO were probably a tad underdesigned for that conversion. The M1943 was built to handle 8x57mm Mauser cartridge pressures.
Best,
Steven"
"Andy, I really do believe that the small ring conversions to 308 did get the ball rolling on the myth that the Spaniards use soft steel. Spain has been making good steel since the days of El Cid!"
"Welcome to the forum!
The Spanish rifles with the so-called heat treating problems (actually it is some compounding factors and not really heat treatment) are the Model 93 mausers that were later modified as the M1916 rifles in 308 (7.62) caliber, or were converted to the FR-7 rifles. The locking lug systems and design of these originally 7mm Mausers do not stand up to a substantial battering with hotter 308 loads. However, the M43 Mauser (called M44 in the Air Force configuration) in 8mm was substantially beefier, and are not a problem.
Too bad your rifle has been modified - the original M44s are bringing a good collectors value these days."
"What I hate to see is what I refer to as "The Lemming Effect" - there are one or two reported cases of problems with a rifle, it gets written about somewhere, so and so heard that their brothers friend had one, --- it snowballs all to heck and everyone jumps on the band wagon, - before long it comes out "ALL SPANISH MAUSERS ARE BAD!"
OK - are we all supposed to build a bondfire and burn our rifles? Sarah Brady sure would be clapping her hands with glee!
Basically, I could do the same thing - say, VZ24 rifles. I have seen one with lug set back and it was obviously unsafe. I could do a big write up, so and so would chime in about their brother-in-laws friends rifle, and before long, low and behold - "ALL CZECH RIFLES ARE BAD" (In the background, Sarah Brady is handing you a pack of matches to light your bondfire).
What it boils down to is: If the rifle functions fine - don't use hot loads, and you should be fine! Do you think a whole country's army would be issued defective weapons?"
"I don't know why the later ones would be controversial. They're the '98 action, and that action has been used to build any number of magnum hunting rifles over the years.
I've got an FR-8, which is a 1943 model converted to 7.62 NATO with a lot of other modifications, and I shoot the heck out of it.
Most of the warnings I've heard are to not shoot commercial .308 Winchester ammo in the converted 1916's and FR-7's, but to stick with 7.62 NATO which is loaded to a bit lower pressure than commercial .308 ammo."
