just because it can doesn't mean it's a good idea...i would bet that any 40g VMax/varmint grenade/blitzking would do just fine

Yep....would never hit a target unless it was right in front of you. Ive havent pushed .224's all that fast yet but in .264 and .284 it seems some of the softer bullets start going apart in mid air when launched from 3500 fps and beyond .
A 35gr .224 bullet is going to be so stubby that any boat tail added would be little more than a small bevel. The biggest handicap that such a light bullet has is its very low sectional density, which lowers the BC significantly, regardless of what shape you make it.
I wouldn't expect many bullets of that weight will be built for such high velocities, they are probably intended more for .22 Hornet type of speeds.

Barnes Varmint Grenades come in 30 and 36 grains. Berger makes a 30 grain bullet. They likely won't hold together either though. They're made for .22 Hornet velocities.
"...can push a 30-35 grain bullet 4900 to 5200 ft/s..." Be very hard on a custom made 22-243 Middlestead barrel. Despite what you see on Reloader's Nest. There are some 5,000ish 30 grain 22-243 Middlestead loads. All using Berger HP MEF's.

Been there done that!!!!
It happened to me just a couple of weeks ago using Hornaday SP SX 55gn bullets at approximately 3000fps through a F10 223 Savage. It has a 1-9 twist I believe. The rifle shoots the same bullet in SP very well.
All kinds of grief before I figured out why I could NOT hit an 8X11 paper at 20 yards. A few key holes gave it away.
You all raised very good points. Now I guess that if I got a 22-243 barrel made, I'd find the slowest possible twist to minimize overspin.
This is an odd idea but... What about making a .22 caliber sabot holding a 30gr .17 bullet that could have a higher BC? Rifling twist would have to agree with the .17 caliber bullet.

I though about the middlestead too but Im leaning towards just 22-250 AI because I hate trimming.
What if you would rechamber a 22-250 14 twist barrel ? I would think you would get the 40 gr. VMAX moving pretty quickly .
If the idea is have fast MV to shoot flat why do you want to shoot bullets that have little bc that will probably prove frustrating at long range in the wind.
How far do you want to shoot ?
This is a bit more of an experiment than a purpose rifle. I think if I was varminting stuff, I'd either be shooting a 6mm or a .17HMR
The 22-243 would be a rifle built more or less for ####s and giggles, just to say "well I'm sending little bits of metal so fast they hit the target before the scope picture even moves from recoil" (quote here is probably an exaggeration but at 5000+ft/s, it's probably not too far off)
