I still want to try that cartridge in a single shot or bolt rifle loaded down as a .25-20, but it's pretty impressive that it almost equals the .250 Savage, very efficient cartridge to say the least.
Looks like an interesting cartridge and probably useful. I fail to see how it could possibly equal the .250-3000's ability to hit 3,000 fps second with so much smaller case, unless the pressure is much higher in the smaller case.Mike replied again today. Saying Both Mossberg & Savage have expressed interest in offering firearms chambered 25/45. He has more things to conquer first but is hoping to move in that direction.
I think in a bolt one could duplicate the 250 Savage 87/3K loading.
I have 300 blk, Grendel & 450 BM in both M$R & Bolt guns & all the Bolts attain greater ballistics with zero pressure signs.
Not that "pushing things" is my intent. But feels better when there are no pressure signs.

100% its pressures! The 250 was low pressure. Remember its age. At the time it was a huge deal to claim such astronomical velocity!Looks like an interesting cartridge and probably useful.

I've never shot the .250 in anything other than a Ruger 77 International, and as I mentioned before I run it pretty hot. Right after I bought the little rifle I bought two cases, yes cases of W-W factory 87 grain ammo. The sun had faded all of the red inked graphics on those cases as they sat in a glass counter for years. The proprietor was happy to sell me both cases. Actually, the gun shop where I bought the Ruger was happy to get rid of it. The owner had paid floor inventory tax on it for 3 years already. I pointed that out during negotiations. He sold it to me at his cost. He told me if the little rifle had been a .243 it would have sold shortly after it hit the rack. He asked me if I'd ever heard of a .250-3000 and reminded me that since I was a hand loader I could make ammo for it.100% its pressures! The 250 was low pressure. Remember its age.

The 25/45 doesn't achieve it in my barrels & I didn't like what it did to brass attempting to reach that! In a bolt gun. It just might!

Back when I was invited to hunt with some guys over by Amherst Junction, a retired game warden had a Remington 722 in .257 Roberts and on one particular day his son was hunting with it. The warden was using a Sako .222 that he had used for a culling assignment. Might have worked well for that, at night, with a light, but for catch as catch can deer hunting I saw him hit two different deer in two days and other hunters ended killing both of the wounded deer with no blood trail to work with.Thats a awesome rifle!! I only ever owned one 250 and it was a custom arisaka 6.5 re barreled and stocked. Actually a pretty and good shooting light rifle. It shot well but wouldnt advise even most manuals data. Arasaka 7.7 can be pretty strong but not sure of the smaller 6.5. Anyhow, I always watched for a 250 or 257 International for my wife as we both loved the looks and handling since shooting a friends 7x57. But its recoil was a bit much for her.
Many manuals offer loads more in line pressure wise to modern rifles. Unlike the 257 where its listed as +P. I have read many times that factory 87 ran shy of 2900 in most rifles. (Probably 20-22" bbls)
Here is some crono numbers I shot in the 25/45.
