.22Lr Loss Of Accuracy.

[ludders76 6]

I have a Brno mod2 22lr. She is a beaut and until recently she was shooting 1" groups at 90 yards. However today at 60 yards groupings have opened up to 2". I am shooting same ammunition type eley subs. I'm mystified, I have cleaned it since loss of accuracy and put 20 rounds through it but still no improvement. Is it me having a bad day???

If it has a mod try it without that way if it's better you know it's the mod. I had this problem and turned out rounds were clipping the mod slightly internally. Since changed mod and back on accuracy. I have the same rifle beautiful rifles

Must be something else, most likely Scope and/or Scope Mounts.

Try taking the scope and mounts off, also the rings off the scope, then 'start again' wind both the turrets fully all the way out

and back, then wind them to mid position, re-mount from the ground up and re zero, if the groups are still cack. I bet the scopes

had it.

Brno's don't wear out or 'go-off', not in 22rf anyway.

Have you give it a good old proper clean

 

If not give it one

Crown of the barrel might also be worth a check and if the barrel is free floating within the stock, make sure it's not touching either edge.

The Eley subs in my CZ452 don't seem to be grouping as well as they did. I put it down to cleaning the barrel (shouldn't have touched it) but perhaps it's the ammo?

Gents thanks for all the advice. I will try all of it. I was head shooting woodies at seventy yards a couple of weeks ago! I'll update when I've done all of the above. Cheers.

I noticed larger groups with eley than I used to get.

 

Maybe the quality / consistency has slipped a little?

Check inside mod make sure projectile exits cleanly not caching inside

Check every screw on your rifle and scope first.

Gents sorry I havent replied. Started a new job and its the curse of school holidays!! Every day off seems to be taken up entertainer my 4 and 7 yr old. Ive cleaned it check the scope, mount and rings. The barrel has never been free floated so I doubt that a problem? Changed mod too. Finger crossed when I finally get out it should all be sorted!

[ludders76 6]

All the above steps have been followed. I went out today, and easily 1" grouping all the way out to 125 yards, Using cci mini mags and eley subs. Thanks for your help advice and experience.

Hope they were on the ground and not in trees ie. background. (Posted in part for the benefit of those newbies arriving via google).

 

Glad to hear you got the accuracy sorted.

What was the problem for future reference thanks

[ludders76 6]

Im pretty certain it was the moderator. I put an old one back on and all seems fine. Superb groups at 50, 100 opening up to 1.5 inches at 150 yards using CCI mini mags.
