22-47 lapua info

[bobinpa]

I am looking for any and all info on the 22-47 Lapua. I am just looking to educate myself on this so anything you can tell me would be appreciated. I am interested in shooting this long range, 500 yards plus, using 80 - 90 grain bullets. Please let me know what you know.
thanks, Bob

Bob-

I shot a .224' cal wildcat for many years, .35 Rem necked-down to .224' cal ).

In a 28' SS K & P 5-groove, I was able to get 3,500fps onto
75gr 'A'-Max w/ a load of 39.5gr AA3100; and FED LR Magnum Match. Accuracy load was obtained by a simple switch to FED LR Match primer. This adjusted load gave 3,420 honest w/ the 75s.
And, enogh power was on-tap to provide an est 450 ft lbs out to 966yd..... good enough for a clean-kill on groundhog
@ 1,000, although I have not realized that goal, yet ).


My point:
For 80-90s..... your powder choice will doubtless end up slow as; or slower-than AA3100.

Best of luck in your endeavors.

I'm still looking for info...... In order to run the 90gr pills, what twist do you need? Can you do it with an 8 tw or does it have to be faster? Does the 47L have the boiler room to do it?
Thanks

If the 47L dosen`t have the boiler room for the 90, the .22-243AI should......


I think Adam had a 22x47L you might want to run this buy him and see if it`s what you are looking for....

Thank you. Who is Adam? Is that his login here?

I like the idea here. I went with a 223AI as I wanted long barrel life along with the mild recoil. Your preferred case will give you plenty of capacity for a 90 grain bullet pushed to a respectable velocity. I love that Lapua 6.5×47L case!

I know we are talking apples and oranges here, but my 26.5" Bartlien 7 twist easily pushes a 80 grain VLD to 2950 without pressure signs (223 Lapua Match brass). I've only shot it to 600 yards, but for the small case and a 80 VLD, it sure shoots flat and is cheap to load for. I never considered using a slower twist than a 1-7" or using anything longer than the 80 VLD. The 223AI is an overachiever, but it ain't magic.

Go for it, but I'd use no slower than 1-7" and keep the barrel long as you can. Sounds like a laser beam.

This is a literal laser beam, I was running 75s @ 3650 as a working load. H4831, H1000, H4350, ect.

I killed a few hogs at extended ranges (300-700) and it makes a mess of groundhogs. I made brass from 308 Palma brass, cci450, I also used a 30" 4g brux 8" twist.

I used it for a season, but I'm using the 22 dasher right now and getting similar results.

Did I miss something here? Adam, why are you making 22x47L brass from 308 brass? The OP was looking for 22x47L info. I think it would be really hard to get 3650 fps with a 75 gr bullet from a case that is just slightly bigger then 22-250 and smaller then the 22-250 improved.

So you're saying that 22x47 can't be made from 308p brass?

I had an abundance of 308p brass so I used it. As to the 3650,then you probably wouldn't like that I got 3700+ with the same load but killed brass in 3 shots, at 3650 I got 5+ reloads.

The truth is the truth.

Adam, Thanks for the info. I assume you went with an 8 twist because you were running 75 gr bullets..... Would you suggest I go with a 7 twist to try the 90gr or would you go even faster twist than that? Also, I assume you see no disadvantage for me to just neck down my 6.5 - 47L brass to get to 22?.?.

No issues whatsoever on the 6.5x47 to 22 caliber. I'd use a 7 or 7.7,but you'll have to be easy on the throttle, those 90s don't like stress. Either way, it'll use all of a 29-30" barrel and a slow powder (h1000, Retumbo, ect. ) as it'll prolong the barrel life. I used only the 75s for hogs, but an 80 would be in line with the best speed vs bc.

Thanks again! I have been doing a ton of reading on this and I am starting to think that I may be pushing my luck wanting to use the 90's. In your opinion am I being foolish? Should I just go with an 8 tw and use the 80's?

I'd use 80s for targeta.

No, not saying that all. Just a whole lot of work involved to make brass for a case that's already avaliable. But, I do know several people shooting 22x47L and are getting no where near that kind of speed. Hell, that's about what Mr Majestic is getting out of his 22-284. I can get only 3550 out of Weatherby Rocket with75s

All I can say is have fun with it.

Adam, it would help a lot of people if you were to post your load with the Dasher with the 75g.

Good luck on that one!
