Lots of interesting options, all. I'm going to start with the 100 grain Hot Cor and Interlock, based on Mule Deer's kind offer.
This is also making me consider chopping a few inches off the barrel to make the rifle handier, given that I don't need to generate high velocity.

MD,
What twist would you recommend to stabilize 120gr bullets in a 25/06? 1-10?

FWIW (me not being MD) I've had no problems stabilizing 120s in a 1-10 twist, even with the slower .257 Roberts, however, one of the barrel makers, I forget which, recommends a 1-9" twist for 120s. Maybe Shilen.
My 120 use has been with flat based bullets ... partitions and hornady pointy hollow points. The longer boat tails might turn out different. If you did go with a 1-9" twist it might open the door to slightly heavier bullets from smaller bullet makers. Neither is a wrong choice.
Another option, if you have a lathe, is to shorten / lighten some X bullets so they would stabilize in your 1-14" twist. It's probably easier to change barrels but for completeness ... gotta mention it.

Pretty much what TOM said--but will note that 120's aren't usually any problem. Only one that I know if is anything but a flat-base, the 120 Sierra GameKing HPBT, and it isn't all that long.
The longest .25 bullets are generally 115-117's, and while they'll all stabilize in a 1-10 twist it might not be ideal under certain conditions. But I've never had any trouble with any 115-120 grain .25's in a 1-10 here in Montana, even in the .250 Savage--though must also note that extra velocity doesn't make nearly as much difference in bullet stability as most handloaders think.
I just ran the 120-grain Nosler Partition in a 1-10 twist at 40 degrees and 3000 feet elevation (pretty typical deer hunting conditions in eastern Montana) through the best twist program available. The stability rating is 1.48 at 2650 fps (typical .250 Savage) and 1.59 at 3300, which is what I load the 120 to in my .257 Weatherby.

Thanks TOM and MD,
Thinking of building a custom 25/06. As far as I know, its hard to over stabilize a bullet and I want to be able to use the full range of bullet weights'
While we're at it, I'm thinking a 24" barrel as opposed to a 22". Any thoughts on length? I wanting t build a sporter usable for game or vermin.

If you're going custom, a 1-9 won't hurt anything and will help sometimes.
Barrel length doesn't matter as much as people think, except possibly in terms of rifle balance for a particular shooter. I've had several .25-06's over the years but right now the only one left has a 26" barrel.

I'd at least try the 110Accubond. If not it then the 100gr Hornady Interlokt. powdr

MD.,
It's a 15 minute drive from my house to G.R.Douglas. So that's where I'm going for a barrel.

That'll work!
I'm sure you're aware that Melvin Forbes uses Douglas barrels on his New Ultra Light Arms rifles. Melvin has told me that he's had really good luck with Douglas barrels in general, their .25 and .30 barrels are exceptional. That's been my experience as well, with three different NULA .25's, a .257 Roberts, .257 Roberts AI, and .257 Weatherby.

The 80 TTSX isn't going to stabilize. The 100-grain Speer should (average length is about .94") as well as the 100-grain Hornady Interlock (.98"). Shhh! Don't let my 1-14 Mark X hear you! It likes the 80grTTSX just fine...

Glad to hear there are other 1-14 Mark X owners. Any other bullets you've used successfully?

100 gr. partition w/nose nipped/filed flat at end of jacket and load it full blast!-Muddy Might give this a shot too! EDIT: just filed down a 100 grain Partition and it looks to be about 0.91" long without the tip. Sounds promising.

Art,
That's very interesting!
I ran the numbers through the Miller computer program, and it came up with a stability factor of around .8--which isn't anywhere close to stabilization. While the program isn't a perfect prediction of stability, the number normally has to be a lot closer to 1 for a bullet to work.
One possible explanation is the bullet length, taken from the Barnes website, may be off. If you have some of the 80 TTSX's handy I'd sure like to find out the measured length.

I know they don't work in a 1-14" twist 99.

That would have been my guess, and as I noted in another post extra velocity doesn't provide nearly as much edge as many shooters assume.
The program does suggest the 80-grain .25 TTSX will stabilize in a 1-12 twist.

The 80 gr. TTSX measures 1.020" and it will not stabilize in either of my two 1:14" 250 Savages.

Thanks for the measurement. That's very close to what the Barnes website lists.

MD..,
Its interesting to see what the pros here recommend and have had experience with. My intent is to build a mostly deer rifle in 25/06.
I'll check with the guys at Douglas n see what they say too. BTW they are a great bunch of guys. No such thing as trade secrets there. Talk to them 5 minutes and they'll walk you thru thr shop n show you how to make a barrel.
