Need some info.

[Matt/TN]

Ok guys I kind of inherited an onlder Herter's XK3 .308win built on a Mauser action. I am trying to find a good factory load to try out of it, but I can't find the rate of twist in the barrel or anythhing like that. Does anyone have ANY info on this gun? I have a good feeling it's probably 1 in 8. If anyone does have a clue, does anyone recommend a good factory load for it?

You may have to measure the twist your self.

I'm betting the twist is 1-10. If memory serves, that's pretty much the standard twist in most .30 cals and I doubt Herters was any different.

Matt...You are going to have to shoot the gun to check what it likes anyway...
I'd start with 150gr Remington CoreLokts, plenty for deer and frankly CoreLokts shoot as well as most factory loadings...After you get used to the gun and have a basis for comparison you can try other loadings...

btw, Congrats on a "new" gun, it's always nice to acquire something that was special to another....Enjoy...

Actually, the industry standard twist for the .308 Win. has always been 1/12". However, I believe Remington made SOME of their barrels, but not all, at 1/10". I doubt that any were ever made at 1/8", however. With Herter's, anything is possible. You need to measure the twist yourself, if you really need to know what it is.

About the only bullet I know of that would need 1/8" to stabilize it at .308 velocities would be the Sierra 240-grain HPBT MatchKing. I have used bullets up to 4 diameters long (Hornady 220-grain RN) in a Model 70 Featherweight(1/12") with 48 grains of Norma MRP for 2300 FPS MV. It was quite accurate. Devastating short-range white-tail load, too!
