Thread: JW 15, or any 22 LR accuracy - group size

From what I could tell the CCI 40gr subs and the Killwell (Whinchester) subs grouped pretty much the same, although the 5th rnd of the Killwell wouldnt feed properly out of my magazine.

I also tried Power Point and Whinchester HV, I gave up on the power point as every second on would fail to extract, the HV seemed to group as well or maybe better than the subs (didnt get to fire as many with the kids in bed though)

I am not sure what your asking here ? Your groups are really good, what are you attending to do ?
If you are a paper puncher then I guess you will always want a smaller / tighter group. Thats the nature of target shooting.

If you want to shoot rabbits etc then your groups are excellent, rabbit won't care how small your groups are and what rifle you are using. All those groups pictured are dead rabbits.

Im pretty much asking what a reasonable group out of a 22lr is as I have no idea really, seems they are reasonable. I got the rifle for my 13th birthday which was over 20 years ago and only got my license recently so havent shoot for years and when I was a kid I never got to go through 200rnds for fun (I probably doubled the number thats gone through it!!). I was probably a little bit worried that it was a bad one as Dads 10/22 seems to shoot a bit better...

So I have found out that it likes the CCI subs and the Whinchester HV (which looks like it may group better in this one) and in the process of going through a few packets of ammo my trigger work got better (if thats a thing) and the groups did tighten up to what is here.

I did also try the Guncity $75 one quickly and it produced similar groups but the magazine didnt want to feed and the 5rnd one was too hard to get out of the stock I made.

That is like asking, what is a reasonable 0 to 100 time for a 2 door car.

There is no universal "reasonable group", what is reasonable depends on what class of rifle you are talking about. Your group is certainly reasonable for a JW15, while it may not be reasonable for a Anschutz 1722.

Chilli - a fair sporting 22 in the hands of a range experienced shooter should shoot consistent sub 1" groups at 50 meters off the bench. A good sporter 22 will average close to 0.5" for groups and drop under the half inch at best (this includes most JWs). Several other makes will achieve this. Best sporter 22 I've tested (Em332) averaged 0.6" over 4 consecutive groups at 100m. Note these figures are for inexpensive standard barrel sporters. Great advantage to choosing a 22 sharpshooter is of course precision bunny shooting out to 100m+ - real treat using an accurate 22 in the field.

You often need to experiment with 10-15 types of sporter ammo to find exactly what shoots/cycles best in your 22, though JW15s often like winchester products and Fiocchi high velocity. Powerpoint HV has been so variable lately I don't buy it any more. Try the Fiocchi HV (blue packet). 5 shot groups are fine - I always do four consecutive 5 shot groups. Pulling shots fairly common as shooters learn to master bench shooting, positional pressures etc. As a new shooter you are doing fine and groups will improve with practice. Sometime go grab a club champ when at range and he will help you one hell of a lot in half an hour.

With ammo cycling remember to CRC your mag after say every second use - keep it lubed. And if you are interested here are some notes on JW setup and development:

Thanks, I might have to look at joining a club for range use, this was in the paddock beside Dads place near Cave (only a 5 min drive to find wallabies though...). I have actually done almost all the mods in that post, I havent mucked around with the trigger too much (just cleaned it up with a stone) I also might try shimming the ejector plate up a bit. I think I will start on a new stock for it as well and Ill do another trigger like this one.
