30 Remington necked down to .224
- Thread starter Cleftwynd
- Start date
The 22/30 Remington would have .001 less diameter on the base, almost .070 longer case, less taper, shorter neck, sharper shoulder, more case capacity and of course, be rimless.
The 22 Savage was based on the 25-35 cartridge which had the 30-30 as a parent case. It is not a necked down 30-30 case though.

The OP should have concluded by now that while what he appears to be considering is not exactly like existing or obsolete rounds, it's not different enough to fill any real gap. It comes down to doing it at significant expense for fun's sake.
I'm a believer Cleftwynd, it is different and not a real difficult change. I like stuff that is just a bit different from what the herd is using. As for new I don't know those guys in the 50's and 60's did a lot of experimenting with cases. I saw a list many years ago in a book or mag that had all the custom reamers Clymer had made and it was a long one. If it looks like a winner to you go for it, talk to the companys making reamers they can tell you if it's been done before or not.

How do you figure this.........of course it's a necked down 30-30 case..........that's like saying the 270 isn't a necked down 30-06...........
22/30/30 Improved (Ackley) a 3030 case necked down to .22 and blown out with minimum body taper and a 40 degree shoulder not sure if this helps.
That's because it's different (22 Savage). It's not directly a necked down 30-30 case. It's a necked down 25-35 which in turn is based on the 30-30 case. A 270 (and 25-06) is a necked down 30-06 so I have to disagree with your comparison. A 280 Remington is based on the .30-06 but with the neck moved forward so it's not directly necked down.
Most wildcats are based on a parent case but not directly necked up or now, and are altered. Shorter, shoulder angle changed and so on.

I still don't want to use a rimmed case, I am not making a revolver cartridge, or using a tubular magazine. As I stated before, I want different. I also don't want a drastic case diameter to bullet diameter ratio.
I've come across several references to various 22 caliber wildcats based on the 25 Remington case but strangely haven't yet come across a name to any of them that are a direct necking down to .224 of any of the Remington Rimless cartridge series.

Neither have I, and it seems to make perfect sense to me. But I would us the 30 case and not shorten it. I think it could be a fun project, resulting in something different yet effective.
The 219 Zipper has a pretty good body taper to it. Just like the 25-35. The 30-30 has a lot less body taper than the other two.
A 30 Remington necked down to 22 cal sounds a lot like the 225 Winchester without a rim. The 225 was kind of semi rimmed to take the same size bolt head as the '06/308 family of cases. Not the larger bolt head size of the 30-30.
The 225 Winchester was brought out a year or two before the 22-250 (IIRC), but the 22-250 being a former benchrest caliber sold way more guns than the 225. That being said, I think that the 225 is very hot on the heels of the 22-250 when it comes to velocity.
I'm going on memory from a few years back, but this is how I remember it. Probably incorrectly.
If you've got the Manual Of Cartridge Conversions you can do a lot of page turning and see if your idea has been thought of before.
