Excellent deciphering of my ramblings!

Here's a commercial Brno SR 98.

Yeah, they say KAR or KARa on the side. 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!

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.

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.

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.

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.

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.
