22XC

[Hammer]

The October-December 2009 The Varmint Hunter has an interesting article on necking down David Tubb's 6XC to 22.

Case capacity between the 22-250 and 22-243.

.

[dfrosch]

Well, since the 6XC is based on a necked up and improved 22-250, it seems like a 22XC would be very similar to 22-250AI.

Did The Varmint Hunter make this comparison?

[J.Baker]

LOL...I read through that article and immediately thought of you Art. The exact words I uttered were, "Hammer isn't going to like this. Now he's going to have to replace all his 'last 220 Swift' barrels with ones chambered for this new-fangled cartridge." ;D

[Hammer]

Nah, nothing will replace the 22 K-Hornet, the 218 Mashburn Bee, the 219 Donaldson Wasp, the 222 Remington, the 222 Remington Magnum, and the 220 Swift.

The 22XC looks like an interesting cartridge -- between the 22-250 AI and the 22-243 in case capacity -- and one I might play with. But think it falls in the category of a paper punching cartridge -- not a varmint cartrdge. Besides, the 22XC would take a custom made die set and everyone knows I wouldn't stand for that.

One should use real cartridges on prairie dogs and groundhogs (rockchucks).

I'm using a 6XC Pac Nor w/8 twist....to me its the ultimate LR 6mm....
Not a powder hog or barrel burner with 36/H4895 & 80-90 gr NBTs
37/H3450 w/107 SMKs

[Hammer]

Currently using the 6 x 47 (6mm/222 Rem Mag), 6BR, 6XC, 6-250, 243 Win, 6mm Rem, 240 Wby, and 6mm-06 Mashburn in the 6mm family.

The 6mm-06 Mashburn with a 30-inch long, 8-inch twist barrel is pretty good out past fifty yards.

Why not just go with a 22-250RCBS improved? Its nothing more than a 22-250 blown out but the 28* shoulder angle is retained. The 22XC is the same thing except with a 30* shoulder.

I used a 22-243 midd reamer (30* shoulder) to short chamber a 22-250 case before. It wasnt worth my time messing with it really. Had nothing to offer over the standard 22-250AI.

[Hammer]

The magazine article said that the 22XC had water capacity of 49.0 grains, but don't know how that was measured.

Haven't measured the water capacity of either the 22-250 Improved or the 22XC or taken the dimensions and calculated the case capacity.

[outlawkyote]

Typo?
The cartridge is made from a 22-250 case blown out to 30* and elongated .145". It cant hold more powder than a 22-250AI. Surely cant hold 22-243 powder capacity since the reamer is held short of full length chambering.

Hammer you didn't list 219 zipper, 22hp, or the 22 rem jet. you must have a couple of those laying around.

Am sure there are some others if I think about it a while.


Some work well for close up shots (less than 25 yards).

Others are better for long range (up to 50 yards).

GUYS THE 22XC WORKS, MYSELF AND A MATE OF MINE SHOOT THEM AND THEY ARE ACCURATE AND FAST. 70GR VLD 3850 FPS AND 80.5GR FULLBORE 3540 FPS. 11MM GROUP THREE SHOTS AT 200 METERS. ;D

Whoa that sounds a lot like my 6mm-250 which runs 37 gr RL15 under 75 gr Hornady HPs & 43 gr of RS-Hunter under a moly'd 90 Speer.

Never tried anything longer than a 100 gr FB Interlock, though.

So old Hammer let the truth be known, what we all suspected. HE CANT SEE PAST 50 YARDS. (Sometimes I have the same trouble)
