I have a 15" '06 what rechamber should I do?I want more power for elk and bear.

I would go with the 06 Improved if it was me even though the cost of dies is more expensive.

i'd leave it alone, because it will make no difference whatsoever on game. the 06 is plenty of power for elk and bear. if you can't kill one with an 06, it will not be the cartridges fault. besides, i know the barrel is a shooter to start with. just my little ol opinion

Honestly, to gain any real power or trajectory gains from a given bullet, you need to launch it 300 fps faster. I just don't think one can burn enough powder in a 15" 30 cal barrel to gain that much over an -06. Even in a 26" barrel, the super mags gain very little over the 300 win mag.

If you want more terminal performance, then you'll need to step up to a bigger bore, not try and gain a wee bit of speed at the expense of hellacious recoil in a 15" 30 bore.

Hey Paul, I'm surprised you didn't tell t/c to go to a .35 rem.?
I have a .375win. in the 12" ported bbl. I would use it on elk out to 100yds w/ the Speer 235gr @ 1800fps (1 1/2MOA all day).

Man,I just need to keep the '06 an '06.KYODE's right my '06 shoots to SWEET to mess with.I just need to get another barrel

FWIW you cannot rechamber a .30/06 to the Improved unless you can set the barrel back, which you cannot readily do with the TC barrels.

By Ackley's definition of an Improved, it first off is shorter from shoulder to breechface by .004," and this is .004" shorter than minimum, not .004" shorter than a chamber that has up to .006" or more of headspace to start with.

Secondly, once you run the reamer in far enough to get a clean neck/shoulder junction, which is what the standard case headspaces on in the Imp. chamber, you will have excess headspace and standard .30/06 cases may not even fire at all, let alone fire without stretching cases.

You can use a .30/06 Imp. reamer to rechamber a .30/06 and then make cases out of .35 Whelan or .280 Rem. brass so as to get the correct headspace, but by Ackley's definition of Improved, this is not an Improved since it will not fire factory ammo correctly..... correctly meaning without stretching cases.

The .30/06 Imp. often does no better than a .30/06 in even 22" barrels, so I doubt you would gain anything in a 15." It normally needs a 24" barrel in order to make much gain at all.

If you try to rechamber the factory barrels to the belted mags, or any other large diameter case, be sure to measure the depth of the scope screw holes. Many are deep enough that when you rechamber, the reamer will cut into the bottom of the holes and "Mag-Na-Port" it at the wrong end.

Excuse to buy another barrel validated.

As a reminder, SAAMI standards for the standard .30/06 are on the modest side due to weaker guns made for the round years to, to wit, the early '03 Springfields and the M95 Winchester lever actions.

So when you look at the ballistics of the .30/06, bear in mind that up to the point where frame flexing causes case stretching and failure, you can load the '06 to the same pressure levels as the .270 Win, which among factory rounds of this type is one of the hottest.

As much as I like the Imp. cases in general, a .30/06 Imp. in a handgun barrel is sort of an exercise in futility.

One friend/customer with both .30/06 and .300 Win. Mag. rechambered factory 15" barrels tells me the .300 Win. Mag. is no faster than the .30/06.
