Best bullet for k31

[sixpointfive]

What are the case lengths for the k31. Just sized a bunch of once fired

madsenshooter, You jogged my memory about the die Joe made: It was indeed a die for a lube sizer, e.g., Ly. #450. I edited my post to reflect that.

I think mine was the prototype Maven. He said he was going to buy a reamer after that.

A fellow on this forum, name now forgotten sent me some samples of a bullet he designed for the K31 in an Accurate mould. The work wonderfully in the Swiss and some other .30 rifles in my batery. I use them paper patched or straight greased. Here is the bullet: http://www.accuratemolds.com/bullet_detail.php?bullet=31-185S-D.png[/URL]

The two K31s I had were very short throated. I gave up on cast in them because of the deep seating required. Milsurp 7.5 ammo was inexpensive then and I couldn't match it's accuracy with hand loads (hang head) so that's what I used.

Ok slugged the bore its .307. I took some Lee 312-160 bullets, gas checked and sized .309. Used 16 gr of 2400 and it shoots a 2"group at 50 and 3" at 100. Yes the bullets are seated deeply because of the leade being so short.

I shoot both the lyman 311299 and the 311413 (the pointy 169 grain, may be off on the mold no) over h4895. both shoot as well as I can hold them, but the 311299 (heavier) seems to shoot a bit better at longer range. 555 yards is the longest I shoot the k31 at and it hits the 12x24 rams regularly if I do my part. I don't have too many rifles that can shoot a cast boolit accurately that far, but the k31 is definitely one of them.

Anybody run unique or have published cast bullet data to share

The 7.5 and the 30-06 have basically the same case capacity and in my older Hogdon manual they list using the same data in both that's for jacketed bullets . The same would apply for cast . And yes I've used Unique under several mid weight cast bullets , 12 -14.5 grs worked well . As others have said numerous cast bullets shoot well in these rifles IF they aren't too big on the nose for your barrel mine would chamber a nose of .301 so a lot of my normal 30 cal bullets worked . Good luck

MY K-31's have not been picky at all about what bullets shoot best. But some of the contenders are:

NEI 308145










NOE K31-180









Bear in mind that most of these groups were shot in matches, and would group much, much smaller from the bench.

I also had good luck with the Lyman 311672, but didn't shoot it in any matches.
