So I got on the 22 creedmoor train and am enjoying the ride. In so much I'm intending to build another one from a Tikka I have. Then I read across something about a 22-284. My wheels are turning but it's posing more questions than I can find answers for. Most of the info I can find is a few years old and excludes 80+ grain bullets. Also what about twist rates at those speeds? I've had a lot of bad ideas and some of these have turned into stupid mistakes howbeit fun mistakes so if you have any insight please share.

Seems like a fun idea.
I can only find one reference to a 22 cal 284 and he shortened the 284 and changed the shoulder angle to 32 winth no loads.

My QuickLOAD is set very conservative unless I have an actual case from my gun that is fired.
That said, it shows 3300-3400 possible with 90g VLD!

I think you would be better off with a 22-243 in 30 degree (Middlestead) or even standard shoulder case. We've gone as high as the 22-6mmRem and some played with the 22-06, but there wasn't much of a gain beyond the older 22-243M. The 284 case capacity is in the same league as the '06, so I would expect similar performance and throat erosion due to severe overbore.
However, if you wish to proceed with the 80-90 grains in mind, I would go with a minimum of 1/8" twist. I have that twist in my 22-250AI, and it works well with the 88's.

Google ".220 redline" for an interesting read. Fella built a .22-300 SAUM. Broke 4000 fps with 75 grain amax.

Here's a great read on the .22-284 but as you note it only goes up to 75 grain bullets. Fella named Bruce Potts built one and shared his findings with those who'd be interested.

The highlight for me is a 30 grain Berger doing 5100+ fps

Bruce Potts might have just created the ultimate barrel-burner with his latest whacky, wildcat creation, how does 5000 fps+ sound?

I lusted after building a rifle to attempt that.

Well I think everyone who's chimed in, is in the same boat as myself. A LOT of speculation.
I might add I have a buddy who's got one that was built probably 30+ years ago and it has like a 1-12 or 1-14 twist and it was built for 50-55 grain bullets so it doesn't translate to anything I can gather.
I'm thinking about a 1-7.7 Krieger if I do this.
Or 1-7 and try those 73 gr Hammers. I just don't like the notion of paying $100 for 22 cal bullets.

In college I pieced one together poorly (college budget and some sketcy gunsmithing).
I'd probably make a wildcat off of the 6.5 prc, the availability of 6.5 prc brass vs 284 would heavily push my decisions that way. Pains me to say it but for a short action wildcat with vld/uld type bullets the 6.5 prc is probably better than the 284...
Think the 2 grain difference on a 22-6.5prc vs 22-284 would be a wash on barrel life.

Primal Rights I think has already done a 22 prc. He has a website and YouTube. His site has a contact page, as well as a phone number at the top. It's an improved prc case, but get specifics from him. He also sells whole rifles.
