Not Interested:
Am not interested in running out to purchase every new AR-15 platform rifle based on a new bullet weight that happens to be very similar to the 223 anyway!
The 300 blk or 308 type AR Platforms have a wider margin of caliber difference from the 223, which makes these more appealing.
Seems to me the 25-45 sharps is similar to the 243. (Am I wrong?)

The claimed ballistics are more like the original .250 Savage, but only with a long barrel. A .250 Ackley Improved or .25 Souper could stomp it out of an AR-10.
Well, a .257 Weatherby would out do them both out of a bolt action. An Ar 10 is not an AR 15. Why so much negativity?
While I love wildcat cartridges, I also know that they won’t change the world. Writers have been extolling .257″ wildcats based on the .222 Remington and .222 Rem Mag for nearly a half-century. Remember John Wootters’ .25-222 Copperhead (mid-1960s), the .25×47 (mid-1970s), or the .257 Kimber (mid-1980s)?
Agreed. People are what change the world!
Just another usless cartridge. If someone wants a 257Roberts, get a 257 Roberts.
http://ramworks.net/blog/neophobia/ Good thing no one said that about the .30-06!
The 257 Roberts of the 21st century is…(drum roll)…the 257 Roberts!
Long after this critter has gone the way of the 25 WSSM, etc, the real ‘Bob’ will still be going strong.
I wonder where these ammo companies are doing their focus groups on all these new cartridges? Calling any cartridge not intended for BPCR use a “Sharps” is a little questionable. Calling a cartridge meant for an AR platform a “Sharps” is downright goofy.
And Richard, we aren’t neophobes, we are paleophiles!
When you can fit a Bob – one of my favorites by the way – in an AR 15 we’ll talk.

What has this got that the 30AR has not?
Aside from the obvious…nothing.
Ever notice how close the .30 RAR is to the Swiss experimental 7.5x38mm GP47 cartridge? Waffenfabrik Bern chambered it in their prototype Stgw 51 rifle .
To me not all will be in production in 5 years. So personally I think the risk of no cases or at best home modified cases only is high. So I will pass.
I’m not trying to sell it or convince anyone to buy it. Different cartridges are fun to work with and shoot. Thank goodness manufacturers and wildcatters know that and keep giving us new toys. Not everyone likes everything but every now and again someone comes out with something that tickles someones fancy. It is a great industry!!!
Case forming shouldn’t be that terrible if you are already a reloader.
6.8 SPC already covers this and readily available. Don’t get me wrong, new calibers are always fun
and sometimes you just want something different. Nothing wrong with that.
Yep, 6.8 is close but for a guy wanting to switch from a 223 it requires a new bolt and new mags in addition to the barrel. AND, some guys just have a thing for .25s. In the end the man behind the gun matters much more than the cartridge.
There aren’t that many AR-15 uppers with quick-interchange barrel assemblies. So most folks will choose a complete upper over the hassle of disassembling and reassembling their existing upper to swap out the barrels. If you are going to pop for a complete upper, you might as well get a complete bolt carrier assembly with a bolt properly headspaced to the new barrel and barrel extension.
That pretty much means that the only parts that will be interchanged will be the magazines. I do worry about whether the forward rib in some magazines will interfere with the wider neck of the .257/45. I also have reservations over Sharps’ claimed increase in case taper.
I grew up hunting with a .250 savage 99 as did my brothers. Any ar15 suitable cartridge that can duplicate the .250 elevates the ar to a higher level. It is hard to beat the effectiveness of the .250 on north American game.
Truth is… Ammunition Technology is greatly enhancing the effectiveness of many firearms. I am glad the industry is researching more heavily projectile functioning. At least we don’t need a World War to achieve this, this time around. 🙂 Nice Info GW…
