Remington 22 HP Centerfire???

[WartHog]

Was up in Mendocino National Forest a few weeks ago camping out & celebrating my 61st b-day at a neat old Deer camp that's probably been in use for ages. Found a very old, damaged but live centerfire round that is marked REM UMC 22 HP loaded with a long .22 caliber round-nosed bullet. Tried searching and turned up no info - what'd I find and what's the cartridge's history?

22 SAVAGE High Power

Now long gone from commercial market. But developed way back in 1912 by Chas Newton as an early high velocity varmint type cartridge.

Hard to find bullets for reloading unless you cast. .228 diameter was weird, even back then.

.228? With a calipers, I'm measuring .2245 right where the bullet protrudes from the casing neck.

People did reload that round with .224 bullets due to ignorance of the proper diameter or simply the scarcity of .228" bullets. I think the usual bullet was 70 gr at 3100 FPS. I had a nice Savage 99 takedown in .22 HP along with some CIL ammo but a really good friend just had to have it.

If a .223 is good for deer and hogs, I imagine a .22 HP is, too.

I have a couple different brands of new and clean cartridges for the 22HP in my collection. Kind of a neat cartridge with a very long neck
