22-20 short? (Read 10565 times)

	Curious about recreating the wheel here. If a 25-20 case were cut down shorter and necked down, would it make a reloadable round of 22LR ballistics? seems like the 22 rimfire, and 17 rimfire characteristics could be duplicated in reloadable form.

	22 Maynard XL is what you are looking for (22 Velodog & 22 CCM are very close in size) I do not have a chamber print of the 22 Maynard XL, Original 22 XL used a .228 bullet newer chamber reamers are for the .224" bullet, it is a re-loadable 22 Mag, easy to load down to 22LR velocitys, CPA chambers for the 22 Maynard XL.

	I wonder if my #2 rolling block could be rechamber for this and work, like rechamber one to 22 mag?

	The Hornet case, I think would be more desireable (and cheaper) for this, I believe. If the Velodog cases are available and cheaper still, I would use them. The 22 RF case is approx. .610 long and the 22 RF sporting chamber is .775 long so, if your looking to duplicate the 22 RF, I would use cases that are .770 long. I've pulled thousands of 22 RF's apart and the powder charge runs between 1.5 and 2.0 of powder that is in the B'eye to WW231 burning rate range. Let us know your progress. Frank

	Looks like Bertram may carry this brass and uses a small rifle primer. Using a cast bullet, looks like it may be cheaper than current .22 prices in the long haul.

	Sounds like the old British 297/230 Morris short & long ctgs...Buffalo Arms Co. has this ready formed brass.

	Just for grins, going back to around 1937... From Col. Charles Askins Quote: "The .221 Askins was the 5.5 Velo-Dog cartridge shortened in length to exactly the .22 long rifle casing; the bullet was the standard .22 long rifle leaden slug at 40 grains. The Velo-Dog was designed to be fired in a French revolver; it had a rimmed casing. My gunsmith and I ran every case through the lathe and reduced the diameter of the rim to the same specs as the .22 long rifle rimfire shell."

I've been thinking about having a small 22 cf barrel made for my CPA Mod 49. I can't seem to find a pain base mould in .225 dia. None of the mould makers I've looked into make them either.

	Does anyone have plain base .22 cal bullet drawings in the 60 - 70gr range they are willing to share? Thanks, Bob

	Really no reason to reinvent the wheel, in my opinion. I'd agree with Frank that the .22 Hornet would make a good cartridge choice, and plenty of reasonably priced brass available without forming. It can easily be loaded to .22LR velocities and use lighter 40 gr. bullets that are closer to .22LR.

	Bob, It's a lighter weight than you're asking for, but some time back, I had B&D cut a plain base mould similar to the old Lyman 225353 design. I recall Barry cutting a mould in a heavier weight that may be closer to what you're after.

	BP I'm once again making bullet moulds on a limited basis, and have a 22 caliber 70 grain bullet that is very accurate at 100 and 200 yards. I will also make 22 caliber moulds as requested. BWDarr
