I am getting confused. Twist is usually thought of as being a "quick" twist for heavy bullets, for example. Years ago the 223 came with a 1-14 for 55 gr bullets. Then people tried 69 gr bullets and went with a 1-9 twist. Now they use 80 grs and use 1-7 twist. If you went to a 90-100 gr bullet you would need a quicker twist say 1-6.5. Correct me if I am wrong.
I have always thought the standard twist to be fine unless you want to shoot heavier than standard bullets. I have never heard that "overstabilization is a problem". If you shoot lightly constructed varmint bullets with a fast twist barrel they may come apart from the higher rpm's however.
I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.

whelennut, you are exactly right!
the bigger, longer and heavier bullets need a quicker twist to stabilize them.
Whatever you are willing to put up with, is exactly what you will have.
When your ship comes in. ... make sure you are willing to unload it.
PAYPAL, sucks and I will never use them again. I recommend you do the same.

Nope, meant 1-19 for 110-125 grain bullets. I got that from the Burger website and that's the minimum twist they recommend for their bullets in that caliber and weight. I think a 1-14 could probably do okay with the those weights but I don't know for sure.
Yes, then the 1-19 is the MINIMUM, or the slowest twist that will stabilize this bullet. So a faster twist, like the 1-14 mentioned will stabilize it but a slower twist say like a 1-28 won't.

Can't argue with your post makes sense to me. Another thing I was wondering if the 30-06 would be considered over bore for a 110-125 grain bullet? If not, what would be considered over bore in a 30-06?

Another nod for RL15 and 125's. I use sierra's with good results. Nothing special in the velocity department, but very accurate.

I believe over bore refers to the diameter of the hole in the tube in relation to the amount of powder capacity in the shell.
I could be wrong...

June,
Don't let the discussions deter you from running varmint bullets in your -06. They are fun, they will shoot accurately, and you only live once.
Try RL15 with either the Sierra 110 hollowpoint or the Speer 125 TNT. Who said the 30-06 isn't good for varmints?!?

you aren't going to worry about overstabilizing a lighter bullet with a 1 in 10 twist...
fragile bullets like the Speer TNT will still hold up to the RPMs generated in an 06 with velocities to 3300 and 3400 fps..
Sierra's 110 gr HP, and the 110 Grain V Max will hold up to 3500 fps in a one in 10 twist from an 06...
What Berger's site is listing, is the recommended minimum twist for the corresponding bullet weights...
Ask a gunsmith about how many 06 rifles he has ever seen with a one in 19 twist.. or a one in 14 twist....
one in 12's yeah, but few in much slower than that....
