22 creed, 22x47L, 22 GT...... which would you build and why?

[dnellans]

I’ve got a 22GT, unfortunately I haven’t gotten around to shooting it yet. It still lacks a bedding job and scope mounting. The round appealed to me because of the small efficient case design, projected barrel life, and the fact that it feeds well from AI mags without the modifications that the BR cases require. I’m looking forward to the day that I actually get to start slinging lead from it.

What bullet? The closet I’ve seen in person has been a 22-dasher shooting 9 atips with rl-16. it could get those moving just shy of 3200 fps. I’d think 22GT should get there with a little less pressure.

60-80 gr bullets hopefully. I’ve got a box of 500 60gr tmk that I’m hoping will shoot well and I just snagged some 80gr eld-m from midway last night that I’m going to try too. I shoot a lot more predators than I do long range targets so I don’t feel the need to mess with the a-tips

If a 22 Creedmoor is to overbore then I guess a 22-250AI and 220 Swift must be too because they all three have nearly the same case capacity and holy cow Batman the 22-243 improved variants and 22-6mm's must be reallllly overbore then and we better not ever bring up a 22-284.

We all like different things for different reasons but you're wanting to launch some pretty heavy for caliber bullets so I'll assume you plan on stretching the yardage out on this build and shooting it at + distances so I'd think the 22 Creedmoor would not only be the easy peasy lemon squeezy choice but that little extra case capacity/velocity would be welcomed. And as for barrel life, it has as much to do with how you shoot it as anything else. Get em hot and keep banging away at it and you can roach the throat in pretty much anything in no time flat. Barrel life in a 22 Creedmore, using your head when you shoot it, will last you plenty long to put many smiles on your face.

Don’t forget the .22 Eargesplitten Loudenboomer!

What in the World is a .22 Eargesplitten Loudenboomer

I scoured the internet trying to find a video of someone shooting the round but alas I came up empty-handed.

22x47......80 VLD's at 3370......

22x47......80 VLD's at 3370......

That would have been my choice if they made head stamped brass for it. Too many rifles and calibers on that case in the same safe here, I’m not the most organized guy in the world.

Nice rifle, nice yote!

I also have a 6.5x47 and several 6x47's.....

To help avoid confusion, I paint my MTM boxes different colors. Works quite well.

I write the rifle it belongs to in big letters on my ammo boxes. Works pretty good, the only time I almost made a mistake was when I left a couple loose ones in my truck. Almost shot a 6x47 out of a 25x47, I caught it but gave me a moment of pause. I’ll probably do a 22x47 at some point, I love that case and have a mountain of brass for it.

I found out a 6x47 doesn't shoot very good in a 6.5x47.

How " short " a barrel are you considering ?

I’ll probably do a 20 or 22 inch barrel, this will be suppressed.

I have had and still have many flavors of 224s. I have 221 AI, 223AI, 22GT, 22250AI and have had other 22250 AIs and 22BR improved. As of right now if I had a do over I would have went with the 22x47 from the beginning and never looked back. Like you I also have the 6 and 6.5x47.
If its being mag fed the 22x47 will likely feed the best. My GT has minor feeding issues as did the 22BR improved. The 22250AIs fed well but do tend to chamber hard at times due to the shoulder angle.
I would also build another 221AI in a heartbeat as it is an absolute blast to shoot.

Now you went and done it, the dreaded feeding issues. This build won‘t be mag fed, just gonna use BDL bottom metal. When you say “minor feeding issues” I take it your talking about a mag fed system but it still begs the question how the GT feeds out BDL bottom metal which is what I want to use for this build. I haven’t read anything about feeding issues with the 6GT which makes me wonder if necking it down to 22 caliber makes it more susceptible to feeding issues. I’ll see what I can find. If anybody has some experience with the 22GT feeding out of BDL bottom metal please chime in.

 

[Txhillbilly]

I love the 22 Creedmoor that I built a couple years ago. I've only shot the 75 gr A-Max / ELD-M bullets out of it, but it'll push them right at 3500 fps out of a 20" suppressed barrel. Knowing that barrel life was going to be on the short side, I just ordered two barrels for it when I started the build. When I shoot the first one out, I'll order a third barrel.

I'm building a new 223 bolt action to shoot the 75 & 80 gr ELD-M bullets, so I'm going to switch to the 88 gr ELD-M bullet's on the 22 Creedmoor and see how they do.

Running them on a prs rig with 10 round mags. I would not consider the feeding issues to be bad but this case still suffers a bit from being too short which causes some occassional binding/shifting issues within the magazine. Its better than the 22BR improved but for sure not perfect. I run 88-95 bullets seated long with custom reamers.
On a BDL it may have zero issues but I have never run one that way?

I’ll mock four dummy rounds and run them through the BDL bottom metal, glad you mentioned it. I’ll be using shorter bullets in this one which won’t help things. Hopefully it feeds just fine, if it doesn’t it’s early in the game and switching is easy at this point. Thanks again for chiming in.

With the barrel length and bullet weights you are considering in that calibre, what powder(s) are you thinking about ?

6xc was designed to feed from a mag... Just saying.

I’m not sure. I imagine I’ll try Varget, H4895, may try some CFE223. One forum member uses AA2700 a lot in 22 calibers med sized cartridges and Ackleys. He likes the fact it doesn’t burn near as hot as some of the others which appeals to me too, I’ll try some of it. I’m not the mad scientist type, looking for a consistent load under .5 with good SD and ES numbers, as soon as I find that I’ll probably be done.
What powders would you try?

Well..... you asked my opinion.....

My .224" cal experiences include a bunch of .222, .223, .22BR,( exposure to .222Mag and .225Winchester ), .22-250, .220 Swift; and my wildcat " .22-35 Remington " . Most of these were 24" barrels, with the .220 Swift having a 26" barrel; and the .22BR 22" lg.

Powder choices:

One consideration is whether you want to use a powder that is fairly insensitive to temperature fluctuations ?

The 20 - 22" barrel length would tend to bias powder choices to those faster in " burn rate " than
WW760, IMR4451, H4350 and similar; while H380 is not touted as being comparatively temp stable.
Neither are BLC2, H335, WW748, or ( to my knowledge ) CFE223. Yet, many of these latter powders have been used to accomplish some great shooting.

I have read that Varget " burns " pretty hot, and its use might negatively impact obtainable barrel life ?
You might get useful vel and perhaps even great accuracy; but @ a cost.

This makes me wonder about use of RL-15, IMR4166 for your application ? H4895 strikes me as being a tad " fast burning " .

All of the above = IMHO .

Always fun to hear where others thoughts are at, lots of good suggestions in your reply!

I guess I’ll mock up some dummy rounds and see how they feed before going to crazy, this might end up going another direction if any problems arise, I’m not expecting any though.
