    Default 3006 Ackley Improved load data

    My absolute favorite rifle is a custom 30-06 Ackley Improved on a 98 Mauser action. I have loaded this with various 150 grain, 165 grain and 180 grain bullets and feel this is a very versitile cartridge for Pronghorn, Whitetail, Mullies and Elk. I have shot this for years and have extensive notes on various loads. This rifle has a number 2 contour, 24" long, 1-10" twist, chamber was cut with a Clymer reamer ("off the shelf dimensions"), headspace set .003" short of a standard 30-06 "go" gauge. Action is a german K98, receiver trued, bolt face trued, locking lugs lapped, glass bedded into a walnut stock, barrel free floated, timney sportsman trigger, etc. Magazine box was lengthened to 3.4". Only minor feed rail work was needed for flawless chambering. The short headspace will "pinch" the new un-formed brass in place for proper fire forming. Standard 30-06 loads were used to fireform the brass. Once fireformed, all brass was trimmed, primer pockets were de-burred and necks were annealed. All brass was neck sized only. Most load development was done with 165 grain Nosler Balistic Tip bullets but there were a few other bullets tested.

    NOW...this is load data developed in my rifle and should not be used in another rifle without slowly working up! Guidelines only!

    Never use the above loads in brass that has not been fireformed.

    Now what I have settled in on as a all purpose hunting load is the 165 grain Nosler Balistic Tip in R-P brass, Winchester LR Primers, IMR 4350, 60.2 grains, OAL set .010" off the rifling. This will average 3,000 fps and is very accurate (under 1/2" @ 100 yards in my rifle). Fine load for Pronghorn and Deer. For elk, back off the IMR 4350 a little and use a 180 grain Nosler Partition loaded to 2,900 fps.

    I have tried a lot of different powders other than the above listed ones. IMR 4895 is too fast burning and will show pressure signs when loading a 165 grain bullet at 2,900 fps. Reloader 22 is really too slow and inconsistant for me.

    Have fun and be safe!

    A quick cross reference to the latest Hornady manual shows your velocities at max and up to 100 f/s over max for a standard 30-06'. That seems reasonable to me for an "improved" and is about the same as some factory 300 Win. mag ammo. That's not bad. My brother has a Mauser 98 that is .338-06'. It's not as nice as yours stock wise as it has a synthetic stock but shoots great. We've only taken whitetail deer with it but I'm sure it would do nicely on some bigger deer type game and black bear.

    Got to ask, can a new in the box Ruger M77 in 3006 be re chambered for the 3006 Ackley improved ??? Is it only a chamber re cut or is there more to it?

    Ackley improved chambers are actually .003" shorter than their parent cartridge...so barrels need set back a little and then the chamber cut. By being .003" short, the un-formed brass is pinched into place for safe fireforming (fireforming using standard parent cartridge loads). So... a "Go" gauge from a standard 30-06 now becomes a "No-Go" and a slightly shorter gauge is used for the new "Go". If your Ruger M77 has no sights installed, then it could be set back just a little bit...say .020" (or less) then recut. If it has sights installed, then a full thread needs set back to re-index the barrel with the sights back on top then the chamber recut. For any gunsmith...this is a simple task.

    milprileb, Most people go to the 35 Whelen when modding the 06' which is a nice caliber too but the 338 fits a nice nitch right in between. You will not regret it. Go with the "33".
