Howdy !

My wildcat .22-35 is .35 Rem necked down to .224" calibre.
This is in same case capacity class as notional .22-47L.

In a 24" Hart SS 5-groove .224 cal barrel, my load was 41.2gr WW760 or 41.6gr VV160 and Fed LR Magnum Match under Hornady 55SX.

In a 28" K & P SS 5-groove, my load was 40.5gr AA3100 and Fed LR
Match under Hornady 75gr "A"-Max. Max vel load used same as above, and FED LR Magnum match for 3,500fps honest. Switch to straight match primer shrank groups nicely, w/ vel redux to only 3,420fps.

My wildcat not based on 6 X 47L, but it's capacity and case dimensions should help give you some sense of what a .22-47 might runwith.

Re: 22/47L

65BR,
That's REALLY close to the 22-250. There might be something to be gained, but that's the closest place to start.
Hope this helps,
Mike

Re: 22/47L

Anyone here just running a straight 22/250/ai Fast twisted?

Thanks for the post all.

I have a 22X47 L Krieger 1:8 twist barrel and two .22/250 AI barrels, one 12 twist and one 14 twist. The 22X47 L has a bit more case capacity than a standard .22/250 and less than the .22/250 AI. All shoot very well. Velocity of the 22X47 L falls between the other two, as you might expect. I did the 22X47 L before Lapua .22/250 brass was available. I had a supply of 6.5X47 L brass and 6X47 L dies on hand, so that was not a problem. Dies for the 22X47 L are strictly a custom item as far as I was able to find. I was able to cobble up some loads using some other dies I had on hand. Now that 22/250 Lapua brass is available, I would go with the .22/250 AI and not look back. No necking down (just fireform) and dies are readily available. I doubt you would be able to find much performance difference, if any, between the two cartridges. Good shooting! Vic

Hi,

This is my first reply on 6mmbr. I re-barreled my Model 70 Winchester Stealth 22-250 to a 22-6XC. I used a Krieger 1:8 twist, my gunsmith used a tight neck reamer, finished the barrel length to 29.250", and heavy ~8 pounds. I been in the testing mode with 75 grain A-Max, Berger, plus using 80 grain A-Max, Berger and JLK's. The A-Max chronograph 3282fps with the best group with a mild load of Reloader 17. Once I have the seating depth under control, I'll be leaning on it. The overall outcome and performance is looking great for next year varmint matches.

Steve, welcome to the forum, ... guys I can vouch for the effectiveness of Steves 22XC as I have seen it in action. It loves any and all 75 grain bullets, and its shooting bughole groups at 4 and 500 yards. He was going to build a 22-250AI, but our smith had the 22XC tight neck reamer (.254) in his shop. Simply neck down 6XC brass, neck turn and you are ready to go. I believe he got his brass direct from Tubbs.

A 22-250 AI with a fast a 8 twist will shred berger and cheek bullets at 3600 fps, but will shoot v-max and b-tips.

 

[65BR]

Good stuff guys, thanks all.

My 700 has a 28" #7 Pac-Nor 8 twist on it and it loves the 75 gr A-max along with H4350 @ a bit over 3500 FPS...
It will turn a crow at 300 yards into a puff of Black feathers..

22-47 lapua can be readily made with 6-47 hornady dies swap out seating stem for vld,and correct bushing and your off to the races.I've built several using various barrels velocity with jlk 80 gr vld's runs 3400fps+ from 25.5" barrel.Just finished 20"22-47 C.P.G. velocities ran about 3240fps avg.Accuracy has been great 1/2 moa through 700yds can see this rifle on cloud peak gunworks web site.The 22-250s run 80 gr bullets comfortably in the 3250 range with26" barrel, good accuracy also.
