Re: .280AI vs. 30.06

Duff , your right about the headspace on the 280 being longer than the 30-06 , you can fireform pretty easly buy just firing the 30-06 brass that was necked down.
you must use a long bullet and seat it out hard into the lands with a light to moderate load. P.O. Ackley wrote about having to use long bullets seated out far to fire for for the 30-06 Gibbs , he even fired standard military ball ammo in the Gibbs chamber to see if their were any ill effects like case seperation , his finding saw no problems but I still woulden't recomend it !!

I'll agree with the folks that like the 280 for its high BC bullets but I'm still a fan if the 30-06Ai. I'm sure that a 175gr MK launched at 3000+fps has got to have a enough thump at 1k for just about any deer.

Re: .280AI vs. 30.06

I have played with the 30 Gibbs and really like its design. I only used 165gr SST due to barrel twist and recoil issues. At 1km, the 7mm 162gr mk were a much better bullet. The Gibbs was going faster then the 280 by about 200fps. Higher BC wins at long range.

If you want bullet weight, go 30gibbs. If you want less wind drift, go 7mm. If your hunting is inside 750yds on deer, it just doesn't matter. For longer ranges, get a bigger cased 30.

All the above caused me to build a 6.5-06 using 140gr SST's. Reason? This is going to be used for clear cut hunting where a long shot is 650yds, most are around 450yds. Wind is a big issue so very high BC is needed. Recoil should be moderate as I don't like hunting with muzzle brakes. Didn't want an improved case due to feeding issues.

After comparing the reg '06 family, I chose the 6.5 because of bullets - SST are amazingly long. Should have a higher BC then even the 142grMK or Lapua. The SST can also shoot in the .1's as proven in my Mytic wildcat.

Put the bullet in the boiler room and any properly designed bullet from 6.5 to 30cal will harvest the deer cleanly.

Re: .280AI vs. 30.06

I use RWS brass in my 280. High quality brass is available for the 280, but it is made in Europe.
I was recently given several hundred once-fired Sako 270 cases. I necked up a sample of them & fireformed with a bullet seated into the lands. They came out perfect.
Another option would be to form cases from 7X64 Brenneke brass. They are very close in size to 280 Rem, but a little longer. They would probably be ideal for forming 280AI.
