Title: New Calibers........
Post by: furbearer365 on January 11, 2012, 06:03:34 PM
In my new issue of Predator Xtreme they are advertising for a new varmint round.  They are calling it a .17 hornet.  How many different calibers do you suppose gunmakers can come up with?  What do you guys think would be a good round to invent next?

A true .338 WSM...  not a .325.

Developed in the 1950's by P.O. Ackley, I really wouldn't call it a new cartridge. It was sort of a wildcat back then, as a necked down 22 Hornet. Hornady is just marketing something that's actually been around for quite some time because of the following of the 17hmr for varmints and such.

I think SAAMI should standardize an AR caliber that uses the .223 case opened up to take 6mm/.243 bullets. Like the .300 blk upper Im building, but lighter faster bullets. That way you can use the same bolt and magazines as .223 and hunt with it. I know there is already a caliber like that in existence but I cant think what they call it.

Maybe I can find a barrel in this caliber..

Why not just shoot the 95 gr load from the .243 ??  Certainly better performance than the 6mm/223.............

Apparently they couldnt get very good velocity or ballistics out of the 338 wsm so they went with the 8mm instead  :dunno: Im still waiting for one as well

A 25 WSM would be nice. Really no need for it though, as it wouldn't be much different than the 270 WSM.

Youre right, but I like the idea of making my AR as multi-use as possible. .300blk isnt really a strong performer either, but it would give me an excuse for subsonic suppressed loads and could also hunt with it if I wanted to. I can just take my .308 if I want more range

Yes I know about that one. I like the full size case better. a 25 WSM should perform about the same as a 257 Weatherby I believe.

Can you elaborate on that? I'm just curious. If I was looking for a new rifle for long range shooting with minimal recoil, I think I'd be looking pretty hard at the 270 WSM. I don't think a 25 WSM would provide any advantage, other than even less recoil. But it sure seems like a 25 WSM should be capable of matching 257 Weatherby velocities.

Oh never mind, I Googled it and found this:

Quote
One of the first wildcat cartridges based on the .300 WSM case to surface is the .25 WSM. (Not to be confused with the factory loaded .25 WSSM.) The .25 WSM was created simply by necking down the short but very fat .300 WSM case to accept .257 inch bullets. Since it is not a standardized cartridge, there are no factory ballistics to compare, and no established pressure standards. At the same pressure established as SAAMI standard for the .270 WSM, the .25 WSM should be able to give a 120 grain bullet a MV of about 3200 fps and a 100 grain bullet a MV of about 3400-3500 fps. These velocities are about 200 fps better than the .25-06 and 100 fps less than the .257 Weatherby Magnum.

Maybe they should come out with a 3006, a 308, and a 223.  I think those would really be efficient and do the job well ;)  JK.

Seriously, though, with all the new cartridges, it's getting to where the old ones look more appealing to me.  I have bought my share of new stuff though, when the marketing geniuses do a good job and convince me to buy!

Why reinvent the wheel?  The 25-06 Ackley Improved will do nearly what the Weatherby will, will much less powder = less recoil than the short mags or the long weatherby cartridges.  Yes, still on a long action though.

I've kind of been thinking a similar thought.  At first it seemed like all the new cartridges were filling in voids in between the standard cartridges....now it seems like the void area has been mostly filled and the even newer stuff has one or two rounds that are virtually the same ballistically, but now you get choice on action length or shoulder angle.  Either way it is pretty cool how much selection is available these days.

 :yeah:

That's actually my mindset now. I remember when I was younger I always wondered why anyone would buy a 30-06. It's too "old" and slow and boring! Now I just really don't think a 30-06 can be beat. My main rifle is a 270 but my back up is a 30-06. Then I have a 243 that I bought for the wife, which will end up being the kids' rifle because she doesn't and won't use it. Yep, pretty boring, 243, 270, and 30-06.  Must mean I'm getting old.

Steve, the 25-06 is a great cartridge, and the 25-06 AI improves on it, but it is not a 257 Weatherby.  Showing one load for the 25-06 AI is impressive, but not necessarily realistic.  I can find loads for a 257 Weatherby that show 100 grain bullets going 3800 ft/second.

With equivalently safe pressures, a 257 Weatherby should beat a 25-06 AI by at least 100 ft/second and more likely 150-200.

The 257 Weatherby is a factory caliber with factory ammunition; the AI is not.

I have nothing about the 25-06 and the AI version, but I don't consider them to be quite the equal of the  Roy. :twocents:

The AI will shoot factory ammo, fireforming it for the handloader. I didn't say or mean that the 25-06 equals the Roy at all. "Near", with less recoil.  Which is my point.. There is no need for a 25wsm. While the 25wsm has nearly the same case capacity of the Roy, to me, that 20% more powder to get a couple hundred more fps isn't worth it as the 25cal AI gives all but maximum velocity that the Roy can, but with often more than a couple pounds less recoil over the 25wsm and the Roy. With given bullet/gun weights, the variable is the powder charge in each case to equal velocities. While the Roy can achieve higher velocities, (and maybe the WSM can do near as well), they will use more powder to do so.  OK.. At this point some say, 'Duh'. But if you're not looking to melt the barrel every time you're pulling the trigger, then the AI wins with cheaper brass, plentiful options from the retail shelf,  -and I just like to point out the AI's to hand loaders because so many people forget about them, to justify that much of the hype on shortmags is nothing more than just hot air. Don't get me started on the 338Federal either! ;)

Title: Re: New Calibers........
Post by: Bob33 on January 15, 2012, 06:11:20 PM
Steve, no offense intended.

The 257 Weatherby does use more powder to get increased velocity.  I don't find the recoil objectionable, but some may.  As for barrel life, I don't worry about that personally because I don't shoot enough through a 257 to burn it out.

The 25-06 AI will shoot factory 25-06 ammo, but at reduced velocity.

A great caliber for handloaders.

I really don't know what else they could come out with?  There really isn't a gap anywhere that needs a new round.  I have had a bad obsession with magnum rifles, 30 cal and 338, but I can't afford to try all the ones out there, so please don't introduce a new one, I'd go broke! 
Title: Re: New Calibers........
Post by: JackOfAllTrades on January 15, 2012, 06:24:23 PM
I take no offense! ;)  This is a discussion, and each of us can justfy our claims.  In fact, for most popular powder choices the Roy needs more powder (as would the 25wsm), in the case for a given bullet to attain the Same velocities of the slightly lesser AI. I don't dispute the Roy's ultra high velocity abilities. I dispute the need for the 25wsm, and that it would provide any noticable recoil difference than the Roy, but that the 25AI should fit the bill as a lesser recoiling long range cartridge. -as was Bobcat's question.

I'll always want a premium 280 ackley, but reality, a 3006, with a 24" tube, a laser rangefinder, some R22, and it'll do anything you want it to in this continent.  The only reason I use my 7STW more is due to it being more accurate, and I'm more used to a rem action.  The flattness of it's trajectory isn't a concern like it was pre-rangefinder days....

7mm WSM, .270 Bullet selection and available weights suck for the true long range game but then again the definition of " Long Range" covers a wide spectrum between shooters. :chuckle:

An Ackley Improved would not fit in the chamber of a standard 25-06. But I do agree that the velocity increase in the "improved" version is negligible, especially when you consider all the extra steps you have to go through in handloading cartridges for it.

Post by: TwoSixFourWins on January 26, 2012, 11:55:06 AM
Doing many ackley improved cartridges is very easy. I have a 22-250AI and with handloads this thing will send a 35 grain bullet over 5000 fps. Yes i said 5000. Typically the idea with an AI round is to get better performance with heavier bullet though. All i do is find a hotter load or factory ammo and shoot it in the gun. Bang....there is your AI brass. Now you just reload it using the AI data instead of standard data. Another reason for doing and AI cartridge is the case and neck angle.  Most guys who do any type of benchrest shooting will tell you there is "magic" in case and neck angle that increases burn efficiency as well as accuracy because there is less bolt thrust. That is why many Bench rest calibers have a nearly straight case with a steep shoulder. I believe in them in most cases. If you reload your own ammo especially.

I don't know how other than factory offerings, the 8x57 is a better cartridge than the .338 Federal. Same as for the 7x57 compared to the 7mm08. The 7x57 is a superior chambering over the 7mm08.

I have a 25-06 AI. It will shoot factory loads the same as before the improvement, and reloads 250 fps faster. It's not a huge gain, but for the $200 bucks it cost me I'm happy with it. Not to much money to have something just a little different. I really like the looks of the AI rounds.  :)
