Re: best twist for the .338 350 gr wildcat bullet?

Trebor,

First off welcome to LRH!!

I have a 1-10 twist in my Kahn and it will handle the 350s out to 500 yards. I have not tested them yet at serious range but will soon.

I am getting 3050 fps in the 338 Kahn. In the Lapua, Richard Graves told me that his factory sako shot the bullets very well as far as accuracy with its 1-9.5 twist I believe it was but velocity was only in the 2500 fps range because he had to seat the bullets so deep. In a properly throated single shot rifle, or repeater used as a single shot, the Lapua would probalby play with the 2750 fps level depending on barrel length.

If I were to build a 338 Lapua and was going to use this bullet, I would look at a 1-9 twist just to be on the safe side.

Good Shooting!!

Trebor,

I am trying to get my 257 and 270 Allen Mags ready for an exotic sheep hunt the beginning of April in Canada but hope to get some testing with the 350 gr ULD in the Kahn as well.

I will report when I get the results of the testing.

You have a great platform for a rifle, obviously you know what it taked to get quality results!!

Good Shooting!!

If the bullet is stable at 500 yards, it will be stable further out as well, more and more stable in fact. This doesn't mean it will be stable through the transonic range, but any stabilized bullet has no guarantee it will either. When the temp drops you may run into a problem if it's borderline stabilized.

Kirby,

What temp and pressure have you tested them in the 10 twist barrel at?

It would be interesting to know (but take more than a few bullets to find out) if you ever slow those bullets down, at what speed they finally go unstable. Seems that the 10 twist might be borderline enough that reducing the speed to 2900 fps or this could begin to happen, maybe.

What's the length of the 350 gr, Kirby?

Brent Moffitt,

I would probably agree with your comments though I have never tested them on paper to see where they start to show nose tears.

I will say that you will not get anywhere near 2900 fps with these bullets. I am getting around 2750 fps and could possible get 2800 with WC872 and that is in the 338 Kahn.

You must be thinking about the 300 gr pills at 2900 fps.

As far as bullet length, the Sierra Matchkings I have measure an average of 1.708" in length, the 350 gr Wildcats measure 1.902" in length.

Basically the same length as a 22-250 case!!!

Good Shooting!!

Kirby,

Here you get 3050 fps, so I'm confused? Not sure where I misunderstand you here??
