caliber choice

I have a somewhat unique problem. The range I belong to has a 1000 yard range. To use the range (due to insurance requirements) it is necessary to attend a class and then qualify on the 600 and 1000 yard distances for the 600 and 1000 yard pins.

I am not at a point where I can build a competitive 1000 yard rifle and don't have enough experience to do it. So, I need to qualify and practice some with what I have.

I have a 6x24x50 scope that I believe is ok for starting. Now I need to pick which rifle and which caliber to set up for qualifying and practicing. All of my rifles, except one, are standard (0ld) Rem 700's, ADL's with pencil barrels. The calibers are
22-250, 243 (700 & 788), 25-06, 270 & 30-06. I reload and can load what I need. I will begin practicing with my standard loads that I have for whatever caliber.

The 788 243 will shoot at about .75" at 100 yards. I have not really tested the others recently enough to have valid data but they all shoot pretty good.

The other problem is that the rifles, except the 30-06, are 1400 miles away. I will be going and bringing some of them, along with reloading stuff, back here. So, I need to reduce the choices down to probably 2 to bring back to work with.

Which would likely be the best to just practice and qualify with? Then I can practice with whatever and decide what action/barrel/caliber I want to build on if I want to chase the 1000k.
 
I'll second the '06.

The factory twist rate will likely be fast enough to stabilize a good medium weight (175-190 grain) bullet, which will have no problem making the distance.

The factory twist rates in the .243 and .22-250 will probably be too slow to stabilize the heavy bullets required in those calibers to cover the distance comfortably.

Good luck qualifying,

To the .30/06 which you already have & thus "doesn't count" towards your go & get 'em limit, I'd add the .25/06, esp. if it is accurate, and is a 1:10 twist -- as most are.

Berger offers a match bullet, as does Randy Robinett. The BIBs (Robinett) is similar to the old 110 Fowler .25, which I have used (successfully) at 1,000 yards with a 26" long, 1:10 twist barrel (Savage factory barrel).

The From the BIBs web site

".25 Cal.- 10 (TEN) Ogive, 110 Gr. FB, BC - .49. Made in Niemi carbide dies: 10 ogive, 0.052″ meplat; .2575 pressure-ring; .2573″ shank. Ideal twist rate: 1:10."

You can get the Berger info from the Berger site.

To qualify, use either the .30/06 or the .25/06, whichever shoots better for you.
 
For practice with the lighter barrels the 25-06 with the 115 Bergers will have lessor recoil.

Pace your shots. The hot barrels do burn out faster.
