    Bullet choose and load for 30-40 Krag

    Just traded for a 30-40 Krag built on a 98 mauser action. Any suggestions for a bullet and powder?

    the usual suspects in the 308/30-06 work pretty much the same in the other 30 cal government round.
    it's all an educated guess,,,, till the trigger is pulled.

    Do you what twist you have?

    If you want to shoot cast, 311299 works is my Krag rifle and my buddy's hi wall and 311413 does well in my Win 95.

    I no longer have any Krags, but still shoot the .30-40 in a Ruger #3 and a Winchester reproduction Model 1895. I've used many bullets in the .30-40, but don't recall anything that was more accurate than Lyman #314299 cast of WW alloy. I size to .311" and also shoot these bullets in .308 and .30-06. Your gun may prefer a .309" or .310" bullet, but I've found most .30 calibers do best with the .311" diameter.

    A lot of .30-40 Krag shooters like the Lyman #311284, but I've never found it to be as accurate as the #314299.

    The Lee 309-200 has become the 'go-to' in my 1898 Krag carbine to the point I've pretty much given up on trying to improve on what I've got. You know, like 'if it ain't broke, don't fix it'?

    The Mauser 98 was never chambered for the 30-40 round, so obviously experience from the 30-40 Krag rifles will not apply. The Krag rifle has a very long and large throat, and I know know about your rifle.

    It is possible to get a 98 action to feed the rimmed 30-40 round, but off hand I would think a bullet that feeds properly would be one of your first concerns. If your rifles has the standard 1-10 twist, then there are many cast bullets that will shoot well in your rifle, deepening of course of the size of the throat, power and powder charge and temper of the bullet.
    Disclaimer: The above is not holy writ. It is just my opinion based on my experience and knowledge. Your mileage may vary.

    That's an interesting conversion, a 98 Mauser to the rimmed 30/40. Keep us posted on your progress with it.

    My favorite 30 and 31 calibre bullet for military calibres are the Lyman designed 311334 and 311299 (also 314299). NOE makes a nice copy of the 299 in both 311, 314 and 316 diameters if your bore is large.
    Keep your powder dry,

    A common conversion for the Siamese mauser however.

    Not too long ago(year or two) someone was selling lots of LR 98 barrels chambered in rimmed cartridges, seems 30-40 was one of them. It seems like they were all Belgium made barrels reasonably priced, Numerich maybe.
    Hell, I was there!

    I believe this one to be the 98 Siamese Action.

    I have a Mirkuru 1895 Winchester in 30-40 and I won two money shoots at my club with the Lyman 311284 over 18.5grs of RX7 with a small tuff of dacron. Boolits will touch at 50yds, if I am having a good day. I am using a Williams peep sight.

    I really liked the 311299 out of my 30-40 #3 rifle, but am seeing that the 311041 is actually beating it in the accuracy department, when lightly loaded with 4759.
    I shoot so that I can handload.

    It sounds like a good candidate for the 30-40 Ackley improved. With less body taper it should feed better than the standard Krag round. I base my opinion on the 30-40 Siamese Mauser I built a long time ago. It fed ok MOST of the time but occasionally didn't. It had a McGowan barrel and shot like a dream with everything I fed it. It's still killing deer for a friend down by the Mexican border. Good luck with yours- in that action you can surpass .308 Win ballistics in the standard case. Best, Thomas.
