.25 Creed! But Why?

I knew the howa 1500 was but didn’t know the vanguard was

Ah they arent. My bad.

Yet for as long as it's been around as a popular wildcat no major manufacturer of firearms or ammunition has chosen to legitimize the 6.5-06.

A-Square submitted their drawings for SAAMI approval for the 6.5-06 A-Square, in 1997.

As far as @Potsie question.

The 25-30TC (25CM) is SAAMI speced with a faster twist rate than the old standard 25 caliber twist rate of 1:10. Meaning you can stabilize heavier bullets.
Otherwise it would top out on the 120gr bullets that the 1:10 does.

So people that don't (or aren't into) custom built rifles can get one over the counter.

Buy a prefit barrel with a 1:7.5 twist and screw it onto a Savage action in 250AI, and you would have a ballistic twin.

Put a 1:7.5 twist barrel on a 257 Roberts AI or a 25-06, and it's an entirely different beast!

As for why 25 caliber over 6, or 6.5mm?
For some unknown reason the 25 caliber seems to kill above what it's caliber would suggest.

Ballistically, the 25-6.5PRC wildcat is equivalent to a fast-twist 25-06 with the added advantage of modern chamber/case design and ability to fit in a short action. That’s the next build on my wishlist.

Agreed and I think they even offered some ammo and had cases so headstamped. No ammo offered from Remington, Federal or Winchester that I ever heard. No commercially made rifles either. Quality Cartridge offered/s brass headstamped 6.5mm-06, but I don't know if they still produce it.

The 6.5-06 A Square doesn't show up on the SAAMI info that I have available.

I have a 25 x 284 that I had made in about 1992. It has a 12 twist barrel. Took it out a few weeks ago and it shot 117 grain Sierras about as well as it did Barnes 80gr TTSX. I recently picked up a few Lapua 6.5 x 284 cases and they chambered as is in my rifle.
