Why does the 30-30 Ackley have such a ridiculously long neck? Here is my idea:

30-30 Improved similar to the Gibbs cases, shortened neck and lengthened body, necked to 7mm. Case capacity on the 30-30 Ackley is 45 grains, my idea would have around 50 grain capacity.

Around 60k pressure using 375 Winchester cases I predict 168 grain Bergers around 2600 fps and 180 grain Bergers around 2450. This is a low estimate too since it would be close to a 7mm-08.

Those speeds translate to 1000 ft lbs of energy to 900 yards with the 168 and 180 grain bullets. Much more capable than the 30-30 Ackley in my opinion.

Wonder what you could do with these:

I need to get mine ready to fireform some brass. I think I will have a shorter neck than the normal AI. Mine was to be a 7-30 Waters, and the chamber was but the bore was a 30 Caliber. 7mm bullets fell all the way through from either direction, so had it chambered for 30-30 imp. The brass coming out of it before had a nice short neck on it. Could be interesting trying to get a load worked up. DP

You guys just ain't right!! I sure am glad I'm.30cal heavy already or I'd be itchin. Kurt

why not 7-08 ? of course if you want to do all the extra work for the same preformance, then knock you self out. If you just have to have a rim, then use the .307 case necked down to 7 with no other change-done. Then again if you want to be the only kid on the block with one----not trying to shoot you down on your project, just trying to help. Bill439

There ain't much help for TYKE he took a couple of 45-120 frames to the head before he figured out that perfect follow thru he has.

Sounds like you done been reading P.O. Ackley's book! Been on my to-buy list, the Volume 1.

Now my thoughts: I like everything about the 30-30AI (even though I've never had one but have thought about getteing one a lot): modest power boost; easy to fireform; plentiful supply of 30-30 cases; better shape of brass; dies available and not terribly expensive; bullets standard and easily available; and lots of load data out there.

Gibbs cases. Hmmmmm. Reducing about 2.5 calibers to 7mm.

Don't know about if it'd be any better than some other rounds.

Now for about the same effort or less you could have a 6.5 Grendel that shoots sub MOA and (in spite of Alexander thinking you need the small-primer cases) can use a donor cartridge's brass that is easy to find.

The 30-30 AI has the absolute beauty that you can fireform existing already loaded 30-30 rounds. The Grendel is a bit more work since you have to resize it and load it before fireforming (if using 7.62 x 39 cases).

If ya do it; I want to know how it comes out for you. I'm not tooled up and experienced enough to play around with some of the wildcat development and certainly don't know enough about it to be properly conversant. HOWEVER, that doesn't mean I don't read and think about them. Probably lots of guys just like me around, too. So have fun and keep us posted!

Don't count on it, depends on the chamber, if the brass isn't supported at the shoulder, the thin brass will split, 3 out of 5 factory Rem loads split on me. $:-\$

I'd like Ackley's book, but I mostly just think on my own.

I don't have enough money to try anything right now, all my ideas are theoretical!

bigvarmnt · « **Reply #11 on:** June 01, 2009, 06:28:39 PM »

Tim, what was the solution to the case splitting problem. Thanks!

quickdtoo · « **Reply #12 on:** June 02, 2009, 05:11:15 AM »

Don't use factory ammo, neck the brass up to .358", then form a false shouder by partially FL sizing it just enough to headspace on the shoulder instead of the rim, steps including pics are shown in the FAQs.

bigvarmnt · « **Reply #13 on:** June 02, 2009, 05:20:35 AM »

Thanks Tim, Sounds a little past my reloading skills. I will look for it in the FAQs though. Could you just tell me the one thing that's not in the FAQS and then I will only have one question.

Sure didn't expect that to be in there. Thanks again Wiki

Lots of good stuff in there, even stuff that doesn't exactly apply to Handis specifically that someone found and shared.

The idea is interesting, but I just don't see this cartridge being very efficient.

Smokin Joe · « **Reply #16 on:** June 03, 2009, 04:26:36 AM »

If the concern is maximum efficiency, you're going to have to stick to the .22 short.

tykempster · « **Reply #17 on:** June 03, 2009, 04:47:43 AM »

I thought it would be very efficient, unless you consider the 7mm-08 grossly overbore.

tykempster · « **Reply #18 on:** June 08, 2009, 04:57:26 AM »

Well appears my idea has been done already. $:-\$

If ya look long and hard enough, yer gonna find most Wildcats have been done before with just a degree or fraction of an inch difference.

If ya can live with that you will save the expense of drawing up your own design and paying a large chunk of change to have custom dies and reamers made.

Should save a feller half or more of the expense, course then it wouldn't be "Yours".
