I want A FAST 22

Very accurate and flat shooting. Only shot at 2 coyotes with it, the first laughed at me, but the second screamed bloody murder before it tipped over.

I have a 6mmAI with a 29" barrel and was thinking about a 22-6AI or 22-284 I have a decent stash of 6mm brass and 6.5-284 Just haven't made up my mind yet, I would be interested in any of your load data if you don't mind

I'm not ignoring you, I'm just busy as [beeep] with only 2 days at home a week. I'll get ya some of my limited data here in a bit.
 



A little Beanland built 22 creedmoor finally came home on Friday. Just have to get my dies from Whidden and I am off down the rabbit hole. Expecting ~3500 with the 80.5gn Bergers.
 
My 22/6mm was reaching just over 4200fps with a 75gr amax and 53.5gr retumbo. I think a 22/6mm AI would fill your speed need just fine and still get 1000 rounds or so out of it
 
I shot woodchucks for some years with a good old time proven 220 swift. 4000 + FPS and sub .5moa with Norma factory ammo Norma 50gr psp @ 4019fps from my Ruger M77V 26 inch HBar. Zero at 300 and it was 3 inches high at 150. Any of the 220 swift loads will be less than 3 inches high up to 300 yards and in the 6-9 inches of drift in 10 mph crosswind. Do you really need any faster or flatter>? I'm currently using a Stevens 200 and shooting Winchester Varmint X in .223, they are 40Gr @ 3700 FPS and its putting 5 shot groupings that can be covered with a dime. Its darn fast and pretty flat shooting. 200 yard zero is 1 inch high @ 100 and only 2 inches low at 250. Easy to source...and wont break the bank. If practicality and expense are no issues...the world is your oyster. For practicality and cost in the sensible range, there are lots of good options. .204 Ruger, 220 swift, 22-250, 223, 243. All are very capable cartridge choices that can be fast and accurate

Finally got it all stuck together with a Bushy DMR that I had floating in the safe and of course the SAS Barricade. Fire formed a couple of rounds for Whidden to make some dies and recoil was a kitten with the 80.5gn Bergers and 40.0gns of H4350. The gun only has 8 rounds on it, and I am already thinking of what can sell now that I have this one built.
223-55fmj / 223ai-69tmk / 22CM-80.5gn Berger @2.64"coal / 22-250

4200fps with the 75gr????? I have friends who have moved on to other cartridges away from 22/6mm because they could never get much over 3500-3600 with the 75-80gr bullets from 26-29 inch barrels so you must have knew something they didn't.
 
I didn't believe I was getting it. The guy I sold it to ran the same rounds I loaded for the rifle and were 4100+. I'm at 3800 foot elevation. He's in Texas somewhere. The first pics I posted with my load on target and my come ups for 500 a member all but called me a liar. All I can say is that's what 2 different chronographs pulled in two different states. I've always got the best velocity with retumbo in the bigger case overbore rounds. We're I was shooting at 51.5gr I was at 3860. Mine had a 25-1/2" hart barrel. Do t know what else to say about it
 
I definitely won't call you a liar as I have not tried it myself just going off what I was told. I do know that a 22/243 AI has similar case capacity and it tops out at 3500-3600 as well with Retumbo

+1

I have a friend that is pretty sharp in the 22/6 AI and he is running 80g A max at 3600, best thing since a Mother's Love, according to him. If my memory is correct, he is running in the slums with about 50g of R#22...don't anybody try that load...just pulled that out of my sketchy memory.

Also, chronographs can really get screwed up and barrels can vary radically. An ultimately slow twist for the bullet could help also. Also, Ratchet rifling may help not to spike pressures along with a Bore Rider Throat. Nastyfish may have found the pot at the end of the rainbow for a load!

I suppose stranger things have happened but this almost sounds a little Unicorn-esque.

I have a standard, not Ack Imp, 22-6mm with a 1-9tw, which is a little slower than most as many are faster twists, and with a 75gr Berger VLD, even before I had the barrel shortened from 28 down to 26, 3600 was about it. Tried a variety of powders and I could squeeze a little more out of it but I could also push new primers in with my tongue on the next loading, and in all honesty, mine shoots much better at 3450-3500 than it does at 3600. I've run it across an Oehler 35P and two different Magnetospeed Chrono's with all three being withing 20 fps or less

That 3600, give or take, with 75-80gr. bullets seems to be where everyone is at and I hear the occasional 3800-ish every so often and I'd bet most of those are running at redline, but we're talking 4100-4200 and that's a HUGE jump above the norm and for me, just a little to big of a stretch to be believable with a 75 grain bullet.

We had a guy that used to praise the velocity of his 338-378 Wby Mag with 300gr SMK's like it was the second coming of Christ. With its 26in barrel he could get 3200 fps with 300's and his loads weren't hot, the bullets weren't seated wayyyyy out, in fact the OAL of his ammo would feed through the magazine. Everyone was amazed and it seemed as though there was just something "special" about that gun. But something just didn't seem quite right and remember I said the OAL of his ammo wasn't real long, well someone got the bright idea to bring a scale to the range and asked to see one of his reloads and weighed it. Hmmm, are these loaded with 250 SMK's or 300 SMK's because mine weigh almost exactly 50 grains more than yours, the question was asked. The response "well I thought they were 300's" lol mystery solved.
 
I got primer pocket swelling at a little over 3900 with the 75 AMAX. Back it down to 3800'ish and it shoots very well and holds pockets tight for a couple of loadings anyway. 30" Lilja 1-8 twist.

Well. I don't have the video anymore of me shooting it over the crony. I posted them on the forum. I'm not one to argue what I cannt prove anymore. So you can call it what you'd like. The new owner is over on accurate shooter. I'll
Try to find my messages and see if he has anything he can send me. But, it's what I got. I had 4.5 moa elevation from 100-500 with. I'll see what I can scrounge up
 
I have a brand new 22 cheetah mk1 and I'm going to attempt to push 55gr Bergers at 4650-4700 fps if they will hold together. The cheetah is capable of 5000 and has been done.
