Is there much to recommend one over the other?

Also, I have a 5gal bucket full of military .30-'06 brass. How hard is it to neck that down to 6.5mm?

probably gonna need to step it down. Use a 7mm neck sizer first then the 6.5.

Everybody can have a 270.... 6.5x06 while not exceedingly rare is unusual and the one I have shoots very well indeed... It like's everything I've fed it, from 120s thru 160s.

6.5 has a different case head dimension than '06 brass. So it really should not be used as you may experience splitting of cases due to not fitting the chamber properly. The case head dimension on a '06 case is .4730" and the 6.5 swede is .4803".

I don't think he's talking about a 6.5 swede chambered rifle, he's talking wildcat.

I'd go with the 6.5-06 just because not everybody has one. I have an old Mauser with a so-so barrel that just might possibly could be rebuilt someday into a 6.5-06 or maybe a .338-06. :) (Of course, I have a .260 Remington/6.5mm-08, so I may be biased toward caliber choice.)

FWIW, I think you'll also need to neck-turn that military '06 brass to get it to chamber properly, unless you want to have a barrel chambered to accomodate the brass as-is after the resizing.

I stay with the .270, because its pretty darn near perfect. I am sure a 6.5/06 would be fine, but when I pick a wildcat to play with, I want a significant inprovment over the stock offereing.

You'll need to do some inside or outside neck turning. Otherwise, you'll have exceptionally thick brass in the neck area, and that will cause excessive bullet tension and higher chamber pressures, something you don't want.

Luckily, there's several other options, to include necking down .280 Remington, .270 Winchester, and necking up .25-06 brass. Of course, all of these need to be trimmed to proper length after resizing.

If you're real resourceful, you can get a batch of either 6.5x64 Brenneke, or 6.5x63 RWS brass, and just fireform it. Those are the European equivalent of the 6.5-06. There's also the 7x64 Brenneke, which is a higher-pressure European version of the American .280 Remington. It makes a fine parent cartridge to form 6.5-06 brass from, too. I use RWS 7x64 brass for my own 6.5-06 loads, Huntington's used to have a 55-gallon drum full of it in Oroville years ago. :D

A-Square legitimized the 6.5-06 a few years ago, and I *think* they still offer properly-headstamped brass for it. I understand A-Square's move chapped Remington's hide, because they wanted to offer the 6.5-06 as a factory round and standardized 700/40X rifle option.

The beauty of the 6.5-06 over the .270 is the variety of high BC (Ballistic Coefficient) bullets in the 6.5/.264" diameter. For some reason, the .270 has always remained a hunting round, and never really caught on as a target or 1000 yard match cartridge, so there aren't as many bullet offerings compared to the 6.5mm, either here or overseas. That's a shame, because it wouldn't take much for an enterprising bullet manufacturer to design and produce a decent, high BC, long-range .277" bullet, either in a hunting or target configuration. Sierra has their MatchKing, but it's rather ho-hum, with a .488 BC.

Until somebody does come up with a better .277" bullet, the 6.5-06 maintains the ballistic advantage out to 1000+ yards.

This is a project that I've thought about for awhile, it should be fairly easy to form brass, and there's a good selection of bullets available for 6.5 mm. Last year I had a .338-06 AI built and I've been messing around with it, it's in the same category as the 6.5 '06 easy to form brass.

If you want to reload ONLY go the 6.5 (.256 Newton is un improved version ) Ackley Imp but if you want the luxury of store bought ammo, that is good to 600 yards (do you shoot farther? where?) and available with superior hunting bullets that were developed over 70 years- the .270 is IT! :p

http://www.hunting-rifles.com/techinfo.htm makes a 150 gr. bonded 270 bullet with a claimed BC of .569. The 6.5 still has the better long range bullets though.

So Rem missed the boat on offering us 6.5/06 guns and ammo huh? I'm shocked. :D

I came across this in a thread over on longrangehunting.com:

chambered for a fast twist 7mm WSM designed to shoot 200 gr ULD bullets which have a B.C. of 1.046

Haven't figured out who makes it, but that is one heck of a BC.
