Excellent deciphering of my ramblings!

Here's a commercial Brno SR 98.

Yeah, good question. While you're at it can a WW1 small ring with large threads be identified without taking the barrel off?

Take-down rifle, good one Z. I spit water on my keyboard reading that.

Yeah, they say KAR or KARa on the side.

Z, just for clarification, what large ring actions would be suitable for reducing to G33/44 dimentions? this question comes up a lot, and although we all take your word as to what actions not to use, i have not seen a list or suggestion of what action you could do this with.

None really. But the technical answer would be any that don't have the LR relief cut in front of the "C" ring. As with all things Mauser you should evaluate each individual receiver for what it is.

The one that does lend it self better than most is the 1909 Peruvian but they cost damn near as much as a real G33/40 and they are only an intermediate length action.

On the K.Kale the thread relief cut directly in fornt of the "C" ring is cut to normal LR depth. Reducing ring diameter leaves you with a wall that is too thin. Much the same as was the problem with the small ring large thread receivers of WWI. If you like takedown rifles, go ahead, lol.

Nope, can't safely do this to a K.Kale.

Have a great time, be safe, and enjoy!

Z, if it's the barrel profile that is the weight savings, why cant you turn the barrel profile on a standard 98 to the same diameter, thus getting the same weight savings? wasnt it you that said you dont need the outer shoulder on the barrel at all, but that we usually leave it there for asthetics? unless you are getting the barrel so thin that the chamber wall becomes an issue, it all sounds like academics to me...

Cuz it looks like shite! You can, but there is a pronounced step that most folks commisioning a custom rifle find objectionable. They like things to blend in and look proportionate. Don't get me wrong, that G33/40 action is lighter and on a mauser even a few ounces helps. But, ltes not forget that on a LR you need a much wider stock to fit the front ring into. It's all about proportions.

The G33/40 was made by the Czechs for the Germans in WWII. It employed several weight saving features including the small ring, relief cuts under the side rails along each side, a thinned left side rail, and a hollow bolt knob. It was a mountain rifle as well as other things. They used to be a dime a dozen, now you can't touch one for under $600 mimimum.

The small rings can be built into very nice light weight rifles but not because the action itself weighs much less, in fact, the SR Mexican weighs the same 48 oz that a standard 98 does. They can be buuilt light because barrel profile can be kept small due to the front ring size. You can turn a 22" SR barrel that weighs just 2 lbs. Plus the stock can be kept trim & thin.

Here's a pic of a nice g33/40 done by Tom Burgess.

The G33/40 is a standard length SR 98

Here's a pic of a Mexican SR 98.

The mexican is intermediate length.

You'll note that the distinguishing feature of the small ring is that there is no step on the left side of the action between siderail and receiver ring. The G33/40 is the exception to this rule due to the siderail being reduced in thickness to lighten the action.

The '06 is higher pressure than the 257 or 7x57 but, if this is primarily a hunting rifle to be used a few times a year I see no reason that it ouldn;t be used. Just keep an eye on headspace. Most of teh Polish variants were better made but, they still have less metal in that area than a standard large ring or small ring small threrad mauser.

Monitor headspace on these frequently because some tend to grow due not to setback but receiver ring stretch. Teh relief cut infront of teh "C" ring is too deep thus the metal too thin in this area. SSome have the tendency to become takedown models. The later made Polish versions rectified this as did later German models. Limit to low pressure rounds and monitor.

The 1908 Brazilian is the 1909 Argie without the hinged guard. Fantasctic fit & finish, provided it is not pitted badly.

Does it matter what type of pan you use for boiling? I have a galvanized drain pan that is big enough to hold a barrel but will the galvanize affect the finish?

A little muricatic acid will take that zinc right off. Just exercise caution and don't breath in the fumes. Fumes never seem to be good for you.

The primary cause of this problem, barring of course wrong thread pitch, is that the receiver is cut for 55 degree threads and the barrel for 60 degree.

The rifle is a highly customized K Kale in a wildcat I call "8x58 bja105." Its a military 8x57 with too much headspace. I make brass from 30-06, sized to fit the chamber. "Customizations" include a bore pitted to resemble the lunar surface, barrel cut off with a sawzall, crown precision cut with a file and a cordless drill, and a cheap scope. This rifle looks terrible, but shoots 1.5" groups with no problem.

I love it! FYI, My first bolt action, a Rem 700 .30-06 never managed better than 1.5".

Rev, good to hear you are coming home. A buddy is returning this week from his tour. Thanks to both of you for all your efforts and sacrifice.

If anyone has one of these shrouds that is too large to screw into a bolt, I want it! I need one to fix a problem I have.

Tight fitting shrouds can be caused by either poor thread fit, interference between the bolt body and the shroud, or both. Lapping is a good way to fix. Just be sure where the interference is first. Don;t just start lapping. You can make things worse. There are other issues that can cause hard bolt lift but it would take too long to cover.

BE CAREFUL WHAT YOU ASK FOR. A SR Mauser means a pre-98.

Do you really want a pre-98 or are you looking for a small ring threaded 98? The SR thread 98 is marked K.Kale. It is a standard 98 action but has SR threads.

If you truely love our system of democracy would you respect the voice of the American people and turn in your guns?

It is because I respect our democracy, especially the Bill of Rights, that I say, hell no! That is the same reason I have issues with things like warrantless surveillance.

The yugo m48 guard will fit and is milled, so is the M24 and 24/47. A Swede guard can be fitted but may be a bit short in mag length. Yours is an M48A if it has the stamped guard.

I kinda like Josey! Look, it's tha Josey Wales.

That's too cool for school.

Here's a link to a post on tool making. http://www.sporterizing.com/index.php?showtopic=1996&st=0

Just so my comments weren't taken the wrong way. I'm finishng up an 8x60. It offers even less performance increase than the 8mm-06 does over the 8x57. That hasn't stopped me though because it is such a must have cartridge.

That's the beauty of handloading and rifle building; you can have whatever you want. Plus, much of this sport is simply a matter of personal prefference. What I like may not float your boat and visa-versa. At this point in time I wouldn't build an 8mm-06 but then you probably wouldn't build an 8x60. :-)

Eventually I'll have one because I seem to be slowly increasing the 8mm's in my collection. Right now they are the 8x57, 8x60 and 8x68. I think BradD has more than me though and he's got that funny 325 WSM, lol.

Sorry, it wasn't meant to be humbling. Perhaps I should have waited til I'd had my second cup of coffee.

:-)

Just trying to help in my own grumpy way, lol.
