So...what are you going to do with them? I know the R. B. Sisk Company was in business as far back as the 40s. Was that box originally marked .224? I understand the bullets were high quality and are considered collectors' items by a lot of people today. Pretty cool, if you ask me. If they were mine, I wouldn't load them. There are actually several boxes of them for sale now on that Popular Auction Site. They'd make a great display.

im gonna keep em,got another unopened box of the 37 gn,got 1 box of 40 gn hornet and a full box of 52gn soft points,my dad got a lot of the 52 gn to use in his rem 722 .222,that thing was amazingly accurate with them,when he gave me the 222 i used them as well,longest shot was 350 yds

Wonder what revolver they were designed to shoot in? .22 Centerfire?

Box states "Revolver"...

Maybe the old "Jet"...........just a wild guess.

I think that the Jet used a .222" bullet. Been wrong before though.

I think Sisk bullets were primarily for rifles, all in .22 caliber and lots of different shapes. Sisk made true custom bullets, jacketed bullets only, and all of them were swaged by hand. His processes were not automated. Varmit hunters loved his bullets.

There are a lot of interesting little details regarding Sisk bullets.

During WWII, copper was what was then called a "strategic metal", and was in short supply for using as a jacket material. Sisk apparently began scrounging used .22 rimfire cases, and using some sort of press, formed them into jackets for his bullets. You can recognize these bullets because they have the original .22 cartridge head stamp on the base of the bullet along with the original firing pin imprint. Remington-UMC cases seemed to be Sisk's case of choice.

There's a good bit of information on R. B. Sisk and his bullets on the Internet. That's where I got this info.

The box looks like what my Dad shot in his .22 Jet. He bought the gun new in 1962 or 1963. I do remember him complaining that they did not expand on groundhogs like he thought they would.

Sisk made them for the 22 Hornet. Your bullets probably date to the '40's or early '50's.I shot a bunch of them when I had a Hornet. Good bullets.

You can still get the kit to make 22 and 6mm bullets out of the 22 rimfire cases from Corbin.
You would have to make thousands of them to pay for it though.
I looked into it when I was shooting a lot of 6mm and decided it was just too much.

my father had one of those presses i remember having to save my rimfire brass for him if i recall the bullets looked a little funny but shot great out of a 222 great for woodchucks

yes the revolver bullets are for the jet,dad got one when they first came out,he and my uncle thought that would be the bee's knee's for varmint hunting around here but they just didnt like it,
