Butch,
Every 30 caliber barrel I have bought from Boots Obermeyer has been a 11 or 11.25 twist. I have called Boots several times and I would be thinking a 10 twist for a new barrel project. He said the only reason a 30/06 was standardized for a .30/06 was to shot the 220 grain bullet. Boots would always talk me into a 11 or 11.25 barrel twist. He says that a 30/06 or 300 mag with 10:1 twist is too fast for anything under a 220 grain bullet. I would suck it up and follow Obermeyer's advice. He must be right because they always shot great!
It is a 11.25 twist. I do know some folks that shot Palma with the same barrel with a different contour. The 220 is great on the 28-30" barrels. I will play with it after building to see what it likes. I believe it will shoot most anything under MOA with a hot, cold, dirty, or clean barrel to the same POA. Good enough to kill whatever I hunt with it to 300 yards.

11.25" twist is perfect for the 308. That's what I'd do.
Anyone that thinks that twist won't stabilize up to 200 grain bullets just hasn't worked with a 308 much. It's a wonderfully forgiving round, where older guys end up after realizing recoil doesn't kill BG animals...

For you, a 30 BR. Use 125 Ballistic Tips. 18”. Just right for deer in Texas out to 300. Super accurate. No recoil.

I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

At one time I had three identical match rifles in caliber .308 Winchester and fired literally thousands of rounds through them. My only perfect scores with a match rifle at 600 yards were fired with the .308, 20 shots prone, slow fire, at a target with a 12" ten ring, fired with iron sights. The majority of shots were also in the 6" "X" ring.
I also have several hunting rifles in .308, including a Winchester Models 70, 88 and a 100. All are deadly on deer. I would recommend the caliber unequivocally.

So, how about the 300 Holland and Holland? Got a bit more style, old school cool, just be fun to build.

Looking through my "stuff" and I found an Obermeyer 11.25 twist 30 cal barrel, both LA and SA Remington receivers. I'm trying to remember if I've ever had a 308, but am leaning that way. The barrel has what I call a Remington mag. contour. It will be a hunting rig. I've wildcated for years, but not really looking to do that on this one. What are your thoughts? What I'd do is ream that dude to a .308 Norma Mag and don't look back. It gives up little to a .300 Win Mag and probably about the same ballstics as a .300 WSM but with more cool factor. A very underrated cartridge.
What goes up must come down, what goes around comes around, there's no free lunch. Trump's comin' back, get over it!

It will be a 308. I have a 30BR, 30-06, 300SAUM, and a 300 WinMag.

I have always leaned towards odd-ball calibers, especially in lever guns. Recently I decided it was time to go more main stream. I looked long and hard at the 350 Rem Mag but the lack of components caused me to look at the 338 Federal. The 308 Winchester is a great base caliber. Nothing great ballistically but consistently gets the job done, so long as you stay within practical limits so far as bullet weight/type/maker and range. And ammo or components are readily available. I always preferred a big bigger bore so I am giving the 338 Federal a try. But the 308 Winchester was a real close second. And if you don't like the 308 Winchester, it can easily be pushed out to a 338 Federal or 358 Winchester while still keeping the short action.

For a lot of my hunting, I have come back to the .308win in recent years. It’s easy to work with for loads, has gobs of components, and isn’t rough on the shoulder. I like tinkering with new stuff and enjoy ballistic gack like many here, but when I was recently looking for a “whatever, whenever rifle”, I went with a mag-sporter 22” SS .308 bolt gun. I’ve never had bad results on game with a .308 either, even with rather sedate 165gr/2650fps loads in carbines. Most of my preferred hunting loads these days are 150/155gr at 2,850+.
Now with even more aplomb

I agree on your choice of the .308, especially if you’re planning on keeping shots inside of 300 yards. No reason to endure more recoil.

Butch, I have to laugh when I see you asking this question on this forum- a bit like throwing raw meat out to a bunch of hungry and bored lions.... LOL
308 for your purposes should be a great choice and fill in your small gap just about perfectly.... IMO...
