Fastest Round?

Can't say that its #1 but the .204 is up there. I think its close to 4000fps.

.17 Rem, .204 Ruger and .220 Swift are at the top of the heap, running in excess of 4,200 FPS.

Handloaded?

Hodgdon lists:
17 Rem = 20 grain bullet at 4,436 FPS.
223 WSSM = 40 grain bullet at 4,362 FPS.
22-250 = 40 grain bullet at 4,224 FPS.
220 Swift = 40 grain bullet at 4,213 FPS.
204 Ruger = 32 grain bullet at 4,081.

Dang!
I think my chronographs " read" slow!

Just bend the thing until the sensors are visibly closer.

Any one know what that new 17 Fireball is clocking?

Hodgdon shows a 20 grain at 4,037 as the fastest load for it.

non-wildcat is a bit misleading. Almost every cartridge STARTS as some kind of wildcat, the 22-250 for example.

I think the point is factory loadings.

Think Barnes will start making a 15 gr Varmint Grenade for the .17 cal guys WOW

Probably the .17 Remington, although .204 Ruger is not far behind.

That's the original .17 Remington, not the new .17 Remington Fireball.

I've seen the low 4100s with 25 gr in .17 Rem.
Took a bit of "tryin" though.

At those velocities, things like altitude, temperature, and barometric pressure can make a pretty significant difference. Not to mention the rifle to rifle variations.

Hodgdon doesn't show the .220 much love, huh? 4,400 FPS is doable with 40 grainers. I personally use 50 grain moly coated V-max's in front of 44.2 grs. H414 to keep it right at 4,000.

What are you shooting? I get 4,245 with 20 grainers from my 700 LVSF (22"). That using 23.0 grains H322

I tend to hot rod stuff, though. I was getting more than 3,900 FPS with 40 grain bullets from my 24" Howa .223 (nice rifle, sold it to fund the .220)

isnt there a .243 load thats above 4000?

Nay. 3,700 is about it with 55/60 grain pills. The 6mm Rem. will eek out another 150 FPS.

Tad knows what it is....the .487 Siberian Buttstomper!

243 over 4000

I think he might need a 22-243 Midleston or 22 Cheetah, but they are not factory options for some unexplained reason

so what is the fastest recorded ever? any bullet and any caliber...curiosity is getting to me.

^ what PT said....but within the boundaries of self-contained cartridges. No railgun or other sci-fi stuff

5000fps? I could of sworn that while watching a show on the Military channel, they mentioned the muzzle velocity from a tank's muzzle (don't know what size/model), as being over 5,000fps with a sabot round.

5278 fps. in a .22-243 Middlestead with a 30gr. bullet
5130 fps. in a .22-250 Ackley Improved with a 35gr. bullet
