rimfire chrony results

[Shiraz]

Anyone chronny their rimfire rifle or pistol ammo?

Maybe we can start a listing for those without chronny's.

reports should probably contain the following:
caliber(.22Short, .22Long, .22Long rifle, .22WMR .17HMR, .17Mach2)
ammo manufacturer
ammo brand/model/type
rifle/pistol make, model
barrrel length
air temp
high MV
low MV
average

anything else?

Probably add Standard Deviation, if the chrony will compute it.

If you have the money buy a CED chrono. It will do every thing that you listed and then some $199.00

So will my shooting chrony Gamma Master, it will also print those numbers so I dont have to waste my time writing them down.

Re: rimfire chrony results

got some agulia 22lr super maximum rated @ 1750fps
from the 16.3" bull ruger 1022 it averaged 1850 @ 15' and 1150 @ 100yards.
shot a 5-6" rock @220ish 8 out of 10

out of a 6" walther sp22 it ran 1450 @ 15'.
it is some smokin 22lr.

Re: rimfire chrony results

So how did you get the 100 yard info?

Did you place the chronny just before the target?

Try this. This was found in under one minute using Google and keywords 22lr and velocities, and a lot of other sites generated hits as well.

Thanks by golly, but that link does not include all the useful info. A Smith 41 has what length barrel?

That report lacks many data points that are needed like....

reports should probably contain the following:
caliber(.22Short, .22Long, .22Long rifle, .22WMR .17HMR, .17Mach2)
ammo manufacturer

Re: rimfire chrony results

Here is some data for you.

22LR
Ammo: American Eagle 40 gr solid (Federal Rimfire AE5022)
Rifle: Savage Mark II BTVS (left hand)
Barrel Length: 21"
Conditions: 66F 29.91" 55% humidity 1200' ASL June 12th, 09 11-1300

I shot a bunch of groups here is the data from a shooting chrony Gama Master.

This group of ammo I had sorted the night before for weight in grains. I don't know if it matters but its included. First time doing that for me. Most 51.5 and 51.6 grains with under 15 each on the 51.4 and 3 range and 51.7,.8,.9 range.
Groups were around the 1" size at 50 yards. often in string shots 1 and 2 a little outside with 3,4,5 touching and very tight. Maybe barrel warming up? Shooter?
A statistics guy might be better able to tell but the 5 shot strings might be a little too few for accurate SD's. I have read that 7 or greater improves SD accuracy.

Shot: # shots in string
High: highest single shot in string in feet per second
Low Lowest shot in string fps
Ave: average of shots in string in fps
ES-extreme spread (high-low)
SD -Standard deviation

Shots:10 High 1249.74 Low:1185.02 Average:1209.87 ES:64.72 SD:18.94 Grains:51.4
Shots:5 High 1243.57 Low 1213.65 Ave: 1224.09 ES 29.92 SD:11.57 51.6grains
Shots:10 High 1253.23 Low 1212.55 Ave:1229.67 ES:40.68 SD:13.56 Qty 8 51.7 2 51.8grains
Shots:5 High 1233.18 Low 1203.87 Ave 1221.01 ES:29.31 SD: 12.40 51.4grains
Shots:10 High 1240.90 Low 1213.16 AVE 1226.98 ES:27.74 SD:9.32 51.4grains this one was a great group.
Shots:5 High 1259.75 Low:1215.48 Ave 1241.67 ES 44.27 SD 18.38 51.5grains
Shots:10 High 1297.70 Low 1218.17 Ave 1243.47 ES:79.53 SD 22.36 51.5grains
Shots:10 High 1252.58 Low 1216.33 Ave 1236.53 ES 36.25 SD 13.30 51.5grains
Shots:6 High 1258.44 Low 1197.32 Ave 1222.94 ES 61.12 SD 20.49 51.6grains
Shots:10 High 1254.92 Low 1162.04 Ave 1229.48 ES 92.88 SD 26.17 51.6grains
Shots:10 High 1246.00 Low 1209.65 Ave 1229.48 ES 36.35 SD 11.57 51.6 grains. Best group at under an inch at 50 yards

Shot some Eley Club too. I found it really hard to group good and wasn't worth the double cost to the AE stuff

Shots:10 High 1050.77 Low 992.78 Ave 1032.52 ES:57.99 SD:15.81
Shots:10 High 1067.36 Low 1012.29 Ave 1044.44 ES 55.07 SD:17.08
Shots:5 High 1050.77 low 1028.98 Ave 1040.29 ES 21.79 SD 8.42
Shots;5 High 1045.42 Low 997.36 Ave 1023.82 ES 48.06 SD: 18.38

I hope that useful. Happy shooting.
