98 mauser in 30-30 win

[bruce drake]

And here I am with a .308 bull barrel and a spare Lee Enfield #4 action that has been looking for a gunsmith to thread the barrel and cut a chamber for 30-30 for almost 2 years.

Magazine and bolt are already setup for a rimmed cartridge and the bullet feeds smoothly into the currently chambered 303 British barrel.

Does anyone want to do a little `smithing for me and do a thread and chamber?

there has been some mausers done in 45/70 why would this be any different

Because those conversions were done on Siamese M98s which had magazines and feed rails made for a rimmed cartridge.

The 30-30 compared to the (left to right) 308 CBS, 308W and 30-06.

I haven't heard or seen a 98 in.30/30 but a former co-worker had one in .32 Winchester Special he bought at a pawnshop.
It came with double set triggers, and a beautiful stock.
I wonder where that ended up as he was a notorious gun trader.

Guess I missed the convert-to-rimless bit.
Reducing the rim to .473" merely creates a semi rimmed case dimensionally the same as the .225 Winchester.

how about useing a 30-40 krag action?

Mr Gibson, is your 308 CBS much different than a 300 Savage?

[rockrat]

Looks like it has a 30-30 length neck, on the 308 case.

I gotta ask........why oh why don’t you just chamber for good old .308W? Any cartridge can be downloaded. 7.62X51 nato and the 98 action almost seem made for each other. Boringly easy. I put a new in the white surplus Israel 7.62 nato barrel on my inherited 1925 Gew rifle that was already sporterized on. 308W is a heck of a cast bullet cartridge as well. Ok, I am done.

Well, sometimes the .308 just doesn't feed well from a 98 Mauser magazine. I'm sure the receiver's feed lips can be machined to allow it if you know what you are doing. I have a commercial FN .308 that chokes on the cartridge, but feeds 7x57 or 30-06 just as smooth as silk. I've been told an 03 Springfield feeds the .308 better than a Mauser.

I have a 219 Donaldson Wasp which uses reformed 30-30 brass on a 98 action. I turn the rims down to .473, feed thru the mag. No problems.

My Original Haenel Mauser came to me in 8.16x46R, then 220 Swift, then 22-250, then 6mm
I did change the 8.15 bolt for the .473 cases.
All was well

Other than the 30-30/30-06 length neck, not really case capacity wise.

The concept was an amalgamation of all the "theories" the major gun writers had on what makes the best cast bullet cartridge. The concept was to have a rimless cartridge with 100% load density using 4895 to drive the 311284 at 30-40 Gvm't velocity. The longer neck would keep the lube grooves inside the neck with the GC seated to the base of the neck. The 2 groove barrel, according to all the experts, was best for that bullet....... As I mentioned, it just didn't work out because I, nor the experts at the time, didn't understand the adverse effect of RPM (RPM Threshold). The experts all held cast bullet inaccuracy above a certain pressure/velocity level was caused because the bullets "stripped" in the rifling.

The 2 groove '03A3 barrel was supposed to better grip the bullets because of the wider lands. Turned out the 308 CBC in the 2 groove barrel shot no better than 4groove and other 2 groove barrels on M1903A3s still in 30-06. Accuracy was very good with all of them when velocity was kept under 1950 fps. Above that inaccuracy with any cast bullet had nothing to do with the number of grooves or the case volume. The inaccuracy above 1950 fps was simply caused by the cast bullets exceeding the RPM Threshold at around 1950 fps as many a cast bullet shooter with 10" twist barrels have found out.

Still, was a good use of a 2 groove '03A3 barrel and a M93 action. However, were I to do it again I would have just chambered it in 30x57 and avoided all the feed problems.......we live and learn.......

You might look at getting a Siamese Mauser trigger housing and using that, since it is designed for a rimmed cartridge. If you go that route, IIRC, you would need a Yugo action to fit the screw spacing of the Siamese trigger housing. Of course, you could do the same thing with the .303 British, which is what Rigby did.

I have a turk mauser that I have converted to 7.62 X 39, it feeds OK had to block the mag because of the difference in cart. length. feeds OK but not smooth. I also have a Turk that the barrel was religned and chambered in 22 Hornet, single shot only. Shoots good but is a pain to load, still working on that.

On the newest of the old 30-30 Mauser Threads, just use a Savage 340 Magazine.
I am sure that you could make it fit.
Rework the bolt face.
Then add an extension on the ejector.
Is there anything else?

I have thought about building a 300 Savage on a Mauser action. I checked the '91, '93, 95, 96 and 98 actions and they all fed it from the magazine with no problems. The '91 seemed to be the smoothest feeding and is also the shortest action and the magazine is single stack. With the coating on the bullets the shorter neck isn't a real big concern.
