Hey guys, I have done a lot of on-line looking, and notice that quite a few of the .204's have a 1:12 twist. I ordered a Les Baer that will be here in 4 months or so, and it has a 1:10 rate of twist. What problems would you think I might encounter if that twist tends to be too fast? I plan reloading with the 39 grain SBK's but don't have sort of pet load worked up yet. Any thoughts?

It will probably shoot all the bullets pretty good. Even the 50 Bergers. My 1/9 twist seems to spin the .204's a little too fast and sometimes they come apart down range. So now I use it only for the 50GR. Bergers. The 1/10 should be just right . I use my 1/12 twist for the 39's.

Cool. I am hoping the gun will be a shooter. He says the rifle will shoot 1/2 M.O.A or better. I see so many rifles with the 1:12 I just wondered why he went with the 1:10.

I have a lothar walther 10 twist on my savage 204 and it shoots the 40 vmax very well. Your barrel should be perfect for the 39 sierra bullet. I wish most manufactures offered a 10 twist barrel for the 204.

Man, that's great to know. It's always nice to hear from someone who has experience with what you might be getting. Do you think it will have any problem with overstabilization of the 32 grain bullets if you push them to max loads?

I'm curious as to what the effects are when one over stabilizes a bullet?

I haven't shot any 32 grain bullets through my gun. The heavy bullets have a much better bc and I'll stick to them. My lothar barrel is very smooth and should shoot the 32 grainers with no problems.

Waldo.....I'm wondering about that one too.

What I mean by that is that you spin a bullet so fast it fragments once free of the confines of the bore. THAT, my friends, is my definition of overstabilization. Under, they tumble, over they splode. Yes I meant splode, not explode.

My opinion. If any bullet is gonna splode it'll be the ones that come in a green box.

Now dats not fair. ALL my bullets are in da little green boxes.

Wel den try em.
Let us know how it goes.


Oh Yeah Wimpy loads don't count. No sense finding an accurate load thats only good for dead calm days

when i started hanging round here some rifles shot 40s, some didnt and it was "diagnosed" as 1 in 12 being the margin of stabilising a 40. So if your barrel was supposed to be 1 in 12 but was actually slightly slower then it was 39s for you.

I ordered a 1 in 10 for my second one specifically to shoot 40s. I havent been calling in here as frequently as i used to so dont know if this is still the current thinking of the majority. Its been a year waiting on a barrel. You guys are very lucky.

Cool! I like be lucky. I'd rather be lucky than good,the saying goes....

And no wimpy loads here man. I didn't buy a .204 to go slow!!

The difference with a barrel that will shoot a 39 grain bullet and won't shoot a 40 grain bullet is not one grain of bullet weight. The difference is the length difference between the 39 grain Sierra and the 40 grain Hornady. The 39 grain Sierra is slightly shorter and thus generally will stabilize in a marginal 12" twist barrel when a slightly longer 40 grain V-Max won't.

"Over stabilizing a bullet" that remains intact to the target is a myth.... It doesn't happen... Too much spin for the bullet jacket may occur, but that is not over stabilization when the jacket ruptures from too many RPM's...
