Can anyone tell me an equivalent of a 22 mag at 100y.... as far as difficulty? For example-
22 mag @ 100y = 308 @ 800y
22 mag @ 100y = 308 @ 800y

Not really concerned with energy, though interesting...... more like if the 22 at 100 is the same challenge as a 308 at 800 or a 338 at 1500....Just ran some quick numbers through JBM. Standard .22mag has about 150ft/lb energy at 100yds. That is equivelant to a 175gr JLK .308 @2700fps @~4000yds. No real comparison. This is strictly from a muzzle energy standpoint.
Magnum.....22 lr or mag? Cause they are two different animals.
I actually think there can be a comparison.... a 223 at 500 is relative to a 308 at 900ish, there just is similarities that warrant a comparison between 22mag and others, anything can be compaired with relativityMakes no sense to compare. Even shooting a .308 on one day is not comparable to shooting the same combo in another condition. ie, wind.
You will never get a number that says if I can shoot my .22 Mag well at x yards I am as skilled as someone who shoots a .308 at 456 yards.
I am going to guess .Magnum.....
Thanks, thats what im talking about!I am going to guess .
a ( .22 mag.) hitting @ 400 yard target X . Is equal to .308 win. lobbing smk's at 1000 yard target X .
.
??Yes, you are correct. Muzzle blast, recoil, wind, drop, rifle weight, eyesight, nerves all make zero difference.
I actually was told yesterday that the National Matches are now going to be shot in a guys basement in Peoria Il with BB guns and the scores translated to 1000 yards with a 300 magnum. Going to save a lot of trouble, target pulling etc.
-Thanks, thats what im talking about!
What is considered accurate from a 22mag? Im getting 15 round groups under an inch at 100y and was thinking that was good.......I think accuracy will be a limiting factor with the 22 Mag. Great rifle Ctg. But not known as super accurate.
Just a factory ruger precision & hornady 30 gr vmax .... it will hit golf balls between 100-125 yards all day long ..... i am not bragging at all, i seriously just figured that was the normThat is exceptional. Drive on.
What rifle and ammo?
22wmr...produced by CCI and then labeled FiocchiUSA, Federal, Remington, Hornady, Norma.
Also produced by Winchester, then labeled Browning.
Also produced by Sellier and Bellot, Armscor, Aguila and RWS.
Only one I haven't tried is the RWS.
All the rest, 2.5 inch spread, or worse, for 50 shots at 100 yards from a barrel block rig.
At 200 yards the cartridge defects cause some outlandish strays.
Winchester throws some so far out they won't stay on the backer.
Supersonic transition, eh?
Do you have any research studies that supports that concept.
I can't find one.
The only study that turns up is one done with the SMK bthp.
A long slender needle nosed tail heavy projectile.
Not a short stubby round nosed bullet.
Studies done with the round nose show increased wind drift.
No reports of problems with transition.
I've been sending rimfire at 200 yards for almost a year.
I'm not seeing anything related to the transition.
Only problems caused by cartridge defects.
If you can link a study showing the round nose projectile and the transition
I'd appreciate it. I can't find one.
Here's two targets shot at 200 yards with similar projectiles, 42 grain Eley 22lr.
Eley Contact rated 1090 fps
50 at 200
That explains a bunch about why we have so much trouble with the 200yd. (properly scaled) rams at my friend Duke's Thorn Hollow Range. They sit at the end of a valley up between two rugged bluffs, the swirls,uneven heating and shadows are pretty challenging (six flags can all be going different...www.rimfirecentral.com
Eley Force rated 1250 fps
50 at 200

Under worse conditions the hi v 22lr did better, even with the supposed "transition".
On a side note I had two chrono's for a while and I was doing tests with rimfire....seeing what the speed was close to the gun, and again close to the target....target being 100 yards away. Problem is with rimfire ammo they.....well I am going to blame a soft loaded round for killing the down range chrono....it did sound and feel different. But before the death of the down range chrono the speed drop at 100 was pretty drastic.
I might buy another one, they are getting pretty cheap and this time I will start with "better" 22 ammo and work my way down, I will not start with thunderbolt.
While they are not inexpensive, you might want to look at a LabRadar instead. The LabRadar will report velocity every .002 seconds which will give you values (slightly more often than) every yard using 22LR standard velocity. If you do get the LabRadar be sure to pickup the optional mic kit for 22.
I have seen the labradar, but never really looked into it as it was pretty spendy for a weekend hobby guy like myself. If it will tell you fps all the way down that is something that really has my interest.
Wonder if it works for pellets, the speed drop there is really amazing...we are talking hundreds of fps at those ranges.
Thanks for the heads up....I will start doing some research.....if nothing else it will stop me from having to haul two of the silly things around.

I use the LabRadar and JBM ballistics website to calculate BC for different ammo per rifle:
Yes, the LabRadar was spendy for a 22LR hobby guy like me. But I've found it useful and a lot of shooters want to borrow it for getting data for their rifles and pistols.
Remember that the smaller the projectile, the harder it is for the LabRadar to pick it up. With 22LR I have a failure rate averaging about 10%. Of the 90% it does pickup, you have a small percentage where it doesn't get numbers out to 100 yards or the SNR (signal to noise ratio) makes the values iffy. I normally just shoot extra rounds and remove any questionable values from consideration within the spreadsheet.
While it should work on 17 caliber, I suspect that the error rate will be a bit higher.
If anyone is in my area, you're more than welcome to meet me at the local range (Eagle Eye Shooting Complex in Mt Pleasant TN) and use the LabRadar.
Hum, your talking 22 LR correct?I've had problems with my 17 cal pellets.
Odd strays that don't fit the mv's recorded.
Not sure if it was transition or pellet defects.
Soft metal projectiles in a metal tin rattling around does bad things to the skirt.
As the pellet exits the muzzle tipping occurs due to uneven pressure release.
See if you can find any studies done on supersonic transition.
Maybe you can find one...my attempts to find any done on round nose bullets came up empty.
The studies done on the SMK bthp show the change in center of pressure causes a wobble.
The problem is that particular bullet shape/weight.
Later studies done with other versions of the bthp didn't show the same extreme effects.
Trying to apply the results from one shape to another doesn't work.
Aerodynamics have different effects as a result of projectile surface profiles.
Ya know, its these kinda answers that give this forum a bad name..... rather than keeping dumbass comments to yourself, you run your mouth and confirm your a douchebag.... you aint shit & never will be in the shooting world...... now tell me how awesomely qualified you are to voice any and all your stupid comments based on your opinion of yourself.... this is a good forum where people should be able to ask questions and pick up tips from the 10% of actual proven shooters, and you certainly aint one of any level of top tier shooter.....Yes, you are correct. Muzzle blast, recoil, wind, drop, rifle weight, eyesight, nerves all make zero difference.
