338.06 VS 30.06 Ackley

Am considering rebarreling my Model 70 30.06. Have killed Elk at 608yds with this gun but have had to pass on several great bulls at longer range due to its limitations. Do not want to have to have any work on the bolt face so the 338.06 or the 30.06 ackely seem like good choices with a shilling or douglas air gauge/fluted barrel.
Hand load using federal brass with 210 match primers and big game powder and Barnes tsx tipped bullets set out 5ths from the L+G's
Any suggestions???

You can order a 338 Gibbs barrel from pac-nor that will be right at a 338 winchester and serve your purpose. Mine shoots the 225 accubond over 2800 fps with a .55 bc. That is a good elk load. I am working with the new 185 Barnes ttsx in it at around 3100 fps. It would also do well.

The Gibbs is all you can get out of a 30'06 case. I have them from 6mm to 338.

Mike,
The cost to open up the boltface is minimal. In my opinion you would be best served for a longrange rig to open it up and build a 338 EDGE. You already have the LA. However, I am not familiar with the Model 70 as having any complications for doing an EDGE build.

Re: 338.06 VS 30.06 Ackley

go with the .338-06 AI. Savage and Weatherby both are soon to chamber rifles in the standard .338-06, and Remington will follow them as well. This means there'll be factory ammo on the shelf, and everytime you shoot a standard .338-06 round you'll be fireform a case in the Ackley chamber! The .338-06 has 85% of the power of a .338 mag, but with only 65% of the felt recoil. The Ackley chamber should pickup a little more power and increase the recoil about three to five percent. Still a win, win situation. The 30-06 AI is an often cussed and discussed subject. It never really put out a serious power gain over the standard case, but did seen to reduce the case growth.

Do you know when these manf's are coming out with this cartridge?

How does the 338-06AI, or even the 338-06, compare to the 338 win mag in velocity?

Re: 338.06 VS 30.06 Ackley

Scott, My 338 Gibbs will match many top velocities in the loading manuals for the 338 winchester but on average is about 75 fps slower than my real loads that I use. My 338 Gibbs is on average about 75 fps faster than my 338-06 imp. So my 338-06 imp runs 50-100 fps slower than most loads I see published in the reloading manuals for the 338 winchester. In reality about 150 fps difference from my actual loads that I use in my 338 winchester. hope that makes since and helps.

If they are coming out with a 338-06 I think the imp would be a good choice since you could buy cartridges over the counter that would shoot just fine for fireforming.

That does help. Thank you.

I agree the AI would be a good option. I reload exclusively but for most of my guns I like loading for cartridges that I can buy over the counter if needed. This seems to fit the bill nicely for a good large game killer at 1/4 mile or a bit further.

Thanks,
