hey guys, the wheels in my brain are at it again. with so many choices in .22 ammo i was wondering about different velocities...everything from sub sonic to high velocity is avalible on the shelf but i am wondering what some of these titles translate into as fps. for example, i have a bulk box of winchester LR and i also have a few 50 rnd boxes of winchester LR high velocity. neither ammo boxes state fps so i'm left wondering if there is an industry standard for fps for different wording or are they the same rounds just in different boxes. just to add more variations into the mix, i've shot some cci mini mags that seemed to crack off and hit harder than some of the bulk stuff and they are rated at 1250 fps. so if someone could make sence of all this to me and throw some fps numbers around it would help. also whats the slowest and highest velocities you've seen and with what brands...the fastest i can find on the web is the cci velocitor at 1435 fps
 
There are faster rounds than velocitors but for the expence of bullet weight. Stingers, Jellow Jackets, Aquilla etc, some reaching over 1700fps at least on paper. Velocities from just sheer wording on a package - subsonic will be 1050 fps or below. Standard velocity is 1070 fps. High velocity could be anywhere from 1100 to 1350 fps, genrally around 1250 fps. Anywhere above 1350 I would say is called hyper velocity.
 
22 velocity

i have put most over the chrony and have found some interesting results.velocitors are right on the money for velocity averaging 1434 for 10 rounds out of a 20 in 10-22.yellow jackets averaged around 1350 and power points 1250 dynapoints come in at around 1150 and are very consistant.stingers go about 1600 but are typically inaccurate.winchester seem to be the most consistant in my experience.federal is all over the map and the cheap remington stuff ie thunderbolts or cyclone i wont even buy any more.i had some eley ten x go auto in my bc bull bbl ruger and all of them went into one hole.basically i go bulk for plinking (dynapoints or federal) and cci velocitors or ww powerpoints for hunting varmints.
 
weight X speed = force
manufacturers decrease bullet weight and increase speed.
So times the velocity and weight together of different rated ammo and see if the force comes out to the same.
 
I have "Ammo and Ballistics" 3rd edition, author Bob Forker, Safari Press (good book to have $27.00). It lists pretty much every factory round made from the 17's to 700 Nitro Express. Give bullet drop info and energy etc as well. Just to give general examples: most standard LR rounds are in the 1030- 1050 fps range. High velocity rounds average 1280 fps. Hyper velocitys 1400 - 1700 fps. If you want a specific rounds info PM me with the info (and product part #). I will need the product # as Federal ,Winchester etc have several types in the same bullet weight.
 
A couple of years ago I bought a Kimber conversion kit for my .45. I tried and chronoed about 20 different types of available of .22LR. Then I compared them to the factory propaganda, it appears that velocity is highly dependant on the barrel length and firearm that it is used in.

Yeah, a short pistol barrel doesn't give the time needed for the gases to fully expand and push the bullet to the advertised(or closer to it) speed.

My question is at what point does that advantage of a longer barrel end?
 
This seems to vary on who tells the story but many years ago it was tested and the barrel length of 18.5 " was the length that offered the optimum avg. velocity, shorter barrels or longer ones showed less vel. This became common knowledge and many gun companies started making barrels of that length for their rifles. That was in the 60's, before Hyper velocity rounds so I don't know how accurate it is today or if it even was accurate then.
 
They're all so close to being the same; the better question to ask is 'which shoots best in my gun.' 22's are typically choosy about which ammo they'll shoot best, and its certainly not worth an extra hundred fps if it means you won't be able to hit what you're shooting at.

If Stingers shoot well in your gun, also try Quik Shok's. Same load, but a fragmentable bullet. Both produce HMR-like effects on gophers (but at much shorter ranges than true HMR's)
 
does high/hyper velocity really make that much of a difference when gopher exterminating in comparison to standard and subsonic? like if you could only find that sub and standard velocity ammo shot accurate and the high/hyper velocity shot less accurate(still accurate, but not as accurate) in your rifle, would you choose the high/hyper over the standard/sub for gophers?

energy wise it doesn't matter, any 22lr bullet be it HP or RN subsonic or hyper - they all pack ample punch to kill gopher. If not instantly poor bugger will die later anyway. The only reason to use higher velocities ammo is to flatten trajectory IMHO. Subsonics, while deadly, they curve down to earth to quick, you will have to judge the distance beginning from 50 yards and on. Anywhere from 70 yards its real ##### to hit little targets reliably, every few yards bullet begins to drop equivalent of critter size.

I have yet to shoot it but I just got a Nylon 66 and it has a 18.5 barrel,I have a real *hit load of CCI Mini Mags I hope it likes them!

Your'e right about the 60's guns,(with exception of the Win 67,with it's 27 inch barrel)my 1948 mod 39A is a 24 inch barrel.

I'm not sure if they had anything as hot as the Mini Mag in 1958 in .22LR(the .22WR is the exception) .
