View Full Version : 25-45 Sharps
Is anyone else sporting this caliber? I built one as a starter hunting rifle, but it shoots so well I'm considering trying my highest magnification scope on it and see how she does at long range (with the right bullet).

Never question the Mods. That is a good way to end up sleeping with the fishes.........
Not questioning anyone in particular, just confused.
Me too. Different reason though. What the heck is a 25-45? I assume it's an old black powder cartridge with a .25 caliber bullet and 45 grains of black powder, but I've never heard of it before.

The name is deceiving, But I guess they went that route, due to it being made by Sharps.
Think .25"x45mm.
It's a .223 based .25 caliber. Made by Sharps Rifle Co.
87gr pill. Uses standard ar components, other than barrel.
I came across this a year or so ago, while researching their Relia Bolt. I think it was just after SHOT 2014.

I've been working some loads with 100gr bullets, and have been very impressed so far.
I guess this is one caliber that hasn't caught on with you guys yet. :)
Huh, learn something new every day. That's an interesting cartridge.

I am sorry. I moved it.
I was not aware of any AR-15s chambered in 25-20 Sharps.

Good point.
My eyes saw 25-45 and my fingers didn't.

... guess it makes about as much sense as the 25 Grendel reamer that just arrived ?

I know there's some big fans of the quarter bore out there, but this one is about the only one that makes sense to me. I'd love to shoot one.

I am curious...what velocities are you getting with what loads? How does it compare with the 6x45?
I get about 2930 with the 85gr Nosler Ballistic Tips in the center photo, and about 2855 with the 100gr Speer HotCor in the lower photo. I can only compare to 223/5.56 and 300 BLK, I've never shot a 6x45.
What's the accuracy like with the heavier pills? I saw BHW was offering this chamber on their barrels a was considering giving it a try. I love my 6 x45 but admit it starts to open up its groups with the 87 grains

My best groups have been less than 3/4 MOA at 100y, with either load. I've hit steel out to 800y with it, too. I'm quite pleased with it. And with 1800+ ft/lbs energy and low recoil, I expect it will be a nice hunting rifle.
My only problem has been pressure issues caused by carbon build up in a dirty chamber from shooting suppressed too much. Otherwise, the SRC barrel has been fantastic.

Anybody seen any barrels for this caliber locally?
I looked around on other forums to see what people were saying about this caliber and it seems like people either love it, or hate it. Kind of like the .40 S&W of the rifle world.
What would the pros/cons of this caliber be when compared head to head with 300 blackout?
300blk has lots of factory ammo choices, and can be shot suppressed. 25-45 hits a lot harder, shoots flatter and farther, and is easier to make & load yourself.

And I'm under the impression that the primary idea behind it is that you can hunt with it.
I think SRC pursued military use as well, but hunting is probably the home run.

What barrel length are you using to achieve these velocities? I've been looking for a new caliber for the wife AR to hunting with, and I may have a few extra bullets laying around in .25 caliber.

I have the 20" barrel with 1-9" twist.

I may have been one of the people posting in the other forums as I've recently seen this pop up. The 6.8 SPC seems to be well liked by AR15 hunters of medium game. One interesting wildcat round that has recently been picked up by two manufactures and is gaining in popularity is the .277 Wolverine. The .277 WLV is pushing 98% energy as a 6.8 SPC at 250 yards with factory loads. You get that performance and all you need is a barrel replacement to shoot it. You utilize 5.56 magazines and bolt.
To clarify, with 6.8 SPC you need a different bolt and magazines, and mag capacity is reduced. The 277 Wolverine is interesting because it follows similar design constraints as 300blk and 25-45 for using the same bolt & magazine (to the same capacity) as 5.56. It is also in the same muzzle energy ballpark as 6.8 and 25-45. I went with 25-45 because of the SAAMI certification, really. The 25-45 also stays supersonic roughly 100y further, but I wouldn't recommend hunting with either one at 900 yards anyway.

Indeed. I believe I indicated above that the ,277 WLV shared 5.56 magazine and bolt above, but perhaps it wasn't clear.

I looked at this round, but I couldn't see enough difference with my 6.5 Grendel to justify. Of course, I shoot a .264 Win Mag compared to my buddy's .25-06 too.
The 6mm to 7mm calibers based on the .223 case needing only a different barrel are gaining ground. I went with the 6.5PCC and have been very happy with it.

Is the 6.5PCC a round that will gain enough traction to have virgin brass made for it, or will you have to fireform your brass for the foreseeable future.

It should, but making the brass is easy and the difference between fire formed and non fire formed is negligible.
