I have a G33-40 receiver with the front scope base holes drilled over the locking lug. I am considering tig welding the holes up and re-drilling in the proper place. I think that it would be best to reharden the receiver. Who does rehardening? Would a color case job do the trick? Mori | ||

A welding engineer and gun crank said there were two rules about welding on a receiver ring...No 1...don't do it and No 2 don't do it. After welding, all the rehardening tricks in the world will not rearrange the grain sructure back to the way it should be...You'll just have a casehardened weld with all the speghetti bowl grain structure. Reaming and driving in a taper pin is safer. You can then make custom bases to utilize the un-offending hole, then drill and tap where proper. If you feel some need to re-heat treat, nothing is really lost. In the quench, the taper pin will harden and strenghten the void | |||

Add to what Duane said and that is the new bases will cover the pin. You wouldn't have to recase then. Butch | |||

I'd use it the way it is. It's not the best way to do it but many have been done that way and they work. John Farner If you haven't, please join the NRA! | |||

What is actualy the problem??????? Eksperts often aprove that you weaken the support for the lower lug by up to 50%. Even that the lower support already is apx 30% weaker than the upper support. Drilling a 3mm hole in the upper lug support, weakens this by less than 5% Even if it is drilled near the edge it realy doesn't matter as the upper lug is split excactly where this hole is, so it doesn't even reduce the bearingsurface. The original Mauser design gives you an action where the action is 30% weaker on the lower support than the upper support. But the bolt is apx 30% stronger on the lower lug  | |||

Hi, This is just a question I made myself for a long time. And, finally, I think making a screw hole in the middle of the upper locking lug support in a Mauser Action, really doesn´t make it any weaker. Because it works like an arc structure. Am I wrong? Thanks PH | |||

I don't know what I'm talking about, but I'll weigh in anyway.... It would seem that a hole in the middle of the lug would give the soft(unhardened) core metal a convenient place to flow if the hardened shell began to fail, as when the lug tries to set-back. I would think that a properly fitted pin would restore most of the strength. Jason "You're not hard-core, unless you live hard-core." _______________________ Hunting in Africa is an adventure.

Belive me a base hole in the upper lug support, has NO negative effect what so ever, on the overall strength of a m98/96/93/g33-40 action. Based on the already mentioned dimentions problems. If anyone is afraid of this issue, they should go for a modern action instead, and not spend anymore on thinkering around actions with crf, and their lack of casehead support. | |||

A properly fitted screw will make it almost as strong as it is without the hole. Use it the way it is and don't lose sleep over it. John Farner If you haven't, please join the NRA! | |||
