Have any of you had any experience with 12T barrels and short freebores shooting the 75-87g bullets in the 25/06, 25 Creed, 250 Savage AI?
12T barrel is what I have.

No experience with a 12 twist but for all intents and purposes the .250AI will pretty much do anything the .25-06 will in a short action with less powder. It is an impressive little cartridge. You might give up a 100fps but anything you shoot with it will never know the difference. The plus side to is you will never have to trim cases and its a very efficient caliber which helps in todays crazy world and prices.
I have a 98 Mauser that been worked over. Shilen 12 twist barrel, it’s 30 inches long and 1 inch at the muzzle. Really heavy rifle to pack around, so it going to be used to knock crow’s over with sand bags on hood of the truck. Only powder I have used was h4831 and 75 Sierra flat base hollow point. Think I started at 57.0 grains went up 1/2 grain and stopped at 58.5 grains, just to check pressure I loaded 3 of each with loads listed it put them all inside of a nickel. It has short throat also so seated them to Sierra manual.
That was standard 25-06
I have 2 Ackleys.
You still need to trim your cases.
Amount removed may not be as much as standard case.
But no need to ever trim is just unrealistic.
While the 250 Savage AI is a wonderful cartridge, it's still below the 257 Roberts AI, speed wise. Which while close, is still below the 25-06.
Barrel lengths being the same.
I shoot the Sierra 75gr HP Varmint in my 250 Savage, 257 Roberts, 257 Roberts AI & 25 WSSM.
Great accuracy!
Although all mine are the more 25 caliber standard 1:10 twist.

Thanks to all!
No but if your barrel can handle a Sierra 100 gr SMK with 52.5 gr of RL19 and a CCI-200 it’s a match made in heaven mines a 1-10 T .

Years ago, I built a Rifle in 25 caliber that was basically a 25/243. I had a reamer that was actually for a 25BR but based on the old Remington brass. By running it in long, it gave about the correct web diameter for the Lapua 243 brass. I simply necked it up, turned the necks to .272, and fire formed to get the 30% shoulder. The throat was .060.
I shot the 82 grn Fowlers out of a 13 twist Krieger at about 3450 fps using N135.
I gave the barrel and loading dies to a friend who still uses it with Speer 87 grn TNT’s. The 13 twist handles the fine.

My 250 Savage (not AI) with a 24" E.R. Shaw barrel pushes the 75gr Sierra HP Varmint just over 3,100 fps. That with Alliant Varmint powder and is an accuracy node, not max.
I haven't chronoed the 100gr & 115gr Ballistic Tips.
Used the 100gr BT this past deer season. Shots 50-70 yards.
While i did take 2 deer, i was a little underwhelmed at the performance. The 100gr needed more speed for shock inducement??
My 257 Roberts with 115gr BT performed much better.
Hodgdon Hybrid 100V is the go to powder for that!
