I'd donate a box if I could. Stuff isn't easy to come by in store. I think I have a few boxes only and keep around to try
I did read years ago about an independent .22 ammo test with a universal receiver "firearm" starting at 26" barrel length. They chronographed .22 ammos, cutting 2 inches off between tests, until they were down to 2" breech to muzzle. (I read this this back before ammo makers jumped on the hypervelocity band wagon.) CCI Stinger was the only .22 LR ammo that had a substantial increase in velocity past 18 or 20 inches of barrel length.
I might have to wait until the first of the month to purchase a new chronograph. But once I get a new chronograph, I will test what ammo I have in my Savage MkII BTVLSS with 21" varmint barrel and my AR22 with a 16" CMMG heavy barrel.
Here is the ammo I have to test;
CCI: AR Tactical 40Gr RN, CCI Mini Mags 40 Gr RN, Standard 40Gr RN
Aquila Super Extra 40Gr RN, Super Extra 38Gr HP
Federal Champion 510 40Gr RN
That would be very interesting , hope you go ahead with it. I will see if I can find these to test with my 18.5" barrel too.
