6.5-06

If I was loading the 6.5/06, I believe I would use either .270 brass or better yet, .25-06 brass, since I don't think its wise to attempt to go from .308 down to .264 in a single pass. With .25-06 brass a 6.5 bullet would be seated in place of the .257, and I might even get away without using the 6.5 expander button from my 6.5X55 die set, if I used boat-tail bullets.
 
Around the year 2002, I had a 6.5-06 that was built by Robert Hart, needless to say, a 26" Hart barrel. It was the most accurate rifle/cartridge combination that I ever owned. It would consistently shoot 1/2" or less at 200 yards. The powder was IMR-4350 and 120 gr. Nosler ballistic tip, and only used it exclusively for antelope. A very pleasant cartridge to shoot. I used 30-06 brass and resized it in the 6.5-06 die to fit the chamber, conducted fire forming and it was set to go, for paper and small big game.

Why did you have to fireform?

Resizing brass from one cartridge to another is not a custom fit for the chamber. Bump the shoulder after fireforming for a custom chamber fit is an ace up the sleeve for increased accuracy.

No need to fireform, especially if you only resize the original brass just enough to have a crush fit into the chamber.

It actually takes very little pressure to form brass, and Full Power loads are the same velocity and same point of aim as with already fireformed cases.

BTDT many times with 223 AI, 25-303 IMP, 250-3000 AI, 6.5-06, 270 Gibbs, 7X57 AI, 280 AI, and 308 Norma Mag formed from 338 Win.

That is my thinking, I've done the same process with many cartridges, never needed to fireform when able to FL size to the new cartridge. I HAVE fireformed alot with many different wildcats and improved cartridges that required it, most of the time with full power loads at the range or while hunting deer, but occasionally with COW and similar... but not in this scenario of taking the -06 down to 6.5.

I do start my load development during the process of fireforming, however prefer to bump the shoulder after the first firing, and yes, I've found better accuracy after fireforming. It's a better custom fit after the fireforming than from the original sizing from 30-06 to 6.5-06.........my experience.
