240 Page Super Pooper
Sometime ago I acquired a Remington 722 that has been nicely re-barreled and then chambered into a 240 PSP. The rifle also came with a set of dies in RCBS 240PSP. Til now, I have been shooting factory 6mm Rems. and they shoot fine...and fire-form the cases to 240 PSP. I am now thinking of reloading. Does anyone have any experience with this round? Reloading suggestions for Deer & Antelope? Results vs the regular 6mm? APPRECIATE ANY INPUT!!! THANKS!!! My new barrel was a .243 with I think a 1 in 9 Twist. Maybe 1 in 10.

I have no experience with the Page cartridge but if no one else responds, I have a 1965 printing of Ackley's "Handbook for Shooters and Reloaders" that has data for it if that information would help you. 0 -
I load mine for accuracy, not speed.
My Win Mod 70 HB likes the following:
85 gr. Sierra HPBT over 35.5 gr. Hodgdon H4895, CCI primer, R-P case,
crimped, seated 0.050" off lands.
95 gr. Barnes XFB over 38.5 gr. Hodgdon H4350, CCI primer, R-P case,
crimped, seated 0.050" off lands. But, XFB's are no longer available.
Both kill deer good, no antelope here in Ga.0 -
Michibay,
Several older manuals have data listed for the .240 PSP. These photos are from my file on the PSP.
From the Speer #5 manual:

Some great info there. But take the load data with a grain of salt, as Speer didn't always pressure-test loads back then - especially with wildcats for which there were no standardized test barrels made.
If I owned one today, I'd adhere to current, pressure-tested .243 Win load data for peace of mind and in consideration of the rifle's age.0 -
nononsense,
Just curious as to the final dimensions of the cartridge. In reading the picture of what you posted, it sounds like the .244 except it has less body taper.0 -
sandwarrior,
There is a little confusion about the Page cartridges.
Warren Page created the Page Pooper from 7.62 NATO brass. It featured a longer neck and sharper shoulder angle than its modern representation as marketed by Winchester in 1955 as the .243 Winchester.
The Page Super Pooper or Souper Pooper, depending on the version of story being told, is the .244 Remington (6mm Remington) with an improved body taper but leaving the shoulder in the original 28 degree angle.
Many of these early wildcat cartridges have great stories behind the development simply because there was so much that could be done and most still had a sense of humor instead of trying to be a cutthroat firearms mogul. This was an adventure into territory with little information to draw from and there was joy instead of greed.
Now we suffer from the speed of light information society where as soon as a 'new' cartridge is released to the public, it's wildcatted up and down the caliber scale within 15 seconds. Then it's a cat fight as to who gets to claim to right of origination... I keep my mouth shut these days and simply work with the cases I like and create what I need or want without worrying about trying to claim credit.

That's kind of what I was thinking. Does your book show a .454" shoulder or .459"? I was one of those wishing in the not-too-distant past that Fred Huntington had straightened out the case. I wonder if it wasn't a Remington thing that the case stayed in it's Mauser body-taper form? They did that to the .257 Rob. It is kind of interesting that in those days, it was often about getting more and more volume. Now in the 6mm's we are working at micro-differences in cartridges a full half inch shorter.
Anyways, we have what we have and if we want changes we can work from there... Thanks again for great information.0 -
My "fire-formed" cases from 6mm Rems look like Weatherby's at the neck. This cartridge does NOT resemble the 243 Win! It's more like Huntington's 243 Rockchucker. Actually it is an IMPROVED 244 or 6mm Rem. Mine is the RCBS version...that might be different from others.
Anyway...it's a NEAT round! THANKS for all the RESEARCH & INPUT!0 -
Michibay,
When you say Weatherby, you mean a double radius shoulder?0 -
Sandwarrior...Yes...it appears so. 0
