I'm thinking about a re-chamber of a Savage 24V.
Its a 30/30 20Ga The 30-30 has always kind of left me flat. I am thinking a ackley improved 30-30 may spice it up enough being its also a 24'' barrel...
I am not worried about collector value, I use my guns. The next guy can worry about values when I'm gone.

.308?

It's your gun but for me the big appeal is the common availability of 30-30 and 20 ga. wherever you go. I have some larger caliber bolt actions for when I want to reach past where the 30-30 goes.

The 308 is a higher pressure caliber plus will not "clean out" a 30/30 chamber. The 30/03 ackley improved is nice bacause you can still safely shoot factory ammo and it's no increase in pressures. Just increases in preformance. CW |

Have you tried re-loading for the 30-30? You could use bullets not normaly available for standard tube fed rifles. Or making a 30-30 "magnum"? Just a thought. Besides,I wonder if anyone else has hot loaded for the 30-30 single barrel?

I do reload and have reloaded for almost 40 years.  I don't think I am going to re chamber it. I have had SS 30-30s for a long time so I have been loading and shooting pointed bullets in the 30-30 for improved ballistics for some time. Although the 30-30 can surely be ''improved'' its not a great idea to try it in actions like the Savage. Its a ''elastic'' action and problems occur pretty quickly. That's why the 24's never got any really hi pressure loadings, the action doesn't do well with them. BUT you are correct, using a spitzer and judicious loadings the 30-30 can be transformed into a more powerful cartridge. (If it was needed) CW |

Although the idea of an improved cartridge has been around since the beginning of the 20th Century, PO Ackley certainly popularized it and probably created more "improved," i.e. blowing out the shoulder to about a 30-40 degree angle....similar to many newer short magnum (SAUM, RUM, WSM) profiles....thus adding powder capacity. The amount of increased capacity depends, of course, on the particular cartridge.
Without making me stand up, walk over and start re-reading my 2-volume PO Ackley 'Handbook for Reloaders...', I seem to recall that his most efficient AI (Ackley Improved) cartridges were cartridges similar to the 30-30 (30-40 Krag comes to mind), but chambered in bolt action rifles. He got 15% (?) improvement in the 30-40 Krag, but less than 10% in the 30-06.
I think your self-administered advice about blowing out the chamber in the Mdl 24 is good. I'd have questions about increasing the chamber pressure in that firearm.
FWIW, a good friend of mine owned and shot a .257 Roberts AI. He loved it, and shot lots of deer and several elk using Nosler partitions. His rifle was a re-barreled Springfield A3 action and was about the handiest rifle I've ever handled. Alas, his son felt the same way, so I was never able to talk him out of it. But....every once in a while, he'd get a wee bit enthusiastic and put too much of maybe the wrong powder in it, and a fired cartridge would stick in the chamber. He'd have to pound out the fired brass with a cleaning rod, after first banging the bolt lever up with a rubber hammer.
I sort of figured that maybe I'd stick to factory loads after that.

I agree. Increasing pressures in these actions may not be a good idea.
BUT just FYI for anyone reading that dosent know . Going to an improved case design and a re chamber will NOT raise pressure and conversely actually REDUCES REAWARD "push" in the improved case. ( minutely but it happens) the improvement in velocity and energy comes from the in tease in powder cap as well as internal volumes to support that.
The precentage of improvement that's another story. But both the 30/30 and 30/06 are old designs when long necks where thought to be required for bullet support and overall accuracy. It was also a time when lead projectiles where more common. It also makes these calibers prime candidates for these improvements!! As we now know that short necks is all that a jacketed bullet really needs. So a substantial increase in capacity can be achieved. First in mo one that shoulder forward and second in reducing body taper to minimum. Modern cartridges like say the 280/7MM express do not see the overall improvement that older designed cases do. After them re loaders know that improvements can be safely made ( in many cases) where modern firearms are chambered for these older cartridges. That's why manufacturers like Hornady can make light magnum versions of regular calibers.
