As I recall, Simmons is just a trade name under which various scopes are sold, manufactured by whoever has spare capacity at the time the order's put in. So sometimes you get one that's been made in Germany and is the dog's doodahs, and other times you get some Chinese-made pile of carp that isn't even worth the effort of setting fire to.

Luck of the draw.

I would recommend the Leupold VXIII 4.5-14x50 Long Range.

Perhaps bit OTT to spend �500+ on a scope for a �100 air-rifle? Isn't there something a bit more reasonable you could recommend?

As for the problem, I've heard something about this sort of thing before, have you searched the various air-gun forums Bois? Could it be you've wound the sights to their limits or something?

What air rifle are you having the problem with....

If it is a spring powered on then resting it on the chair could be the problem......it would probably cause it to be very inaccurate.

(Unless it's an AA TX200 SR, or a Whiscombe etc etc ((UNLIKELY))!)

What you need to promote is free recoil.
Try bundling up a towel to rest the rifle on, and hold it loosely....

Put the target at approx 10m.

Wind the adjusters fully in one direction (but not TOO fully!!!) then wind them all the way to the other end of their adjustment, counting how many revolutions or clicks......Then wind them both half the way back.... The scope 'should' be centred.

Remember when adjusting at 10m, you will need a larger adjustment for a small change than at 25m.

If the scope says one click it 1/4 inch at 100m. Then it should take 10 clicks to move the point of impact 1/4 inch at 10m.

If you cannot get the point of impact to move far enough to hit where you think you are aiming, you could have a mounting issue.
Check the mounts are on straight. Are they decent mounts?? Or El cheapo chineese from Fleabay???

Expensive scope would be lovely, but a bit overkill on even a reasonably priced spring air rifle.

Personally, I would say you would be better to spend your money on something like an HW77k (new or spookily the older sometimes the better!!!), and a second hand half-decent scope...from someone reliable, who won't rip you off!!! For possibly under �200 you will have a combination that if it performs.....will be better than you or I will ever be!!!

Just my thoughts.

I have to agree, I would suspect the scope is moving. I have the 77k originaly with two point mount and it kept sliding foward with each shot. Changed it for a full contact mount and it�s fine now.

Thanks for all those very helpful comments. The rifle is an Air Arms so it's a good quality piece of kit and does much more than 12ft lbs! I shall have a try again with the scope this afternoon. I'm hoping for success because I have the offer of pigeon shooting in a barn this week. Thanks once again. Just another reason why I love this site.

Doing much more than 12ftlbs.........If this IS a spring powered rifle, then it is possible that it has KILLED your scope.

Most scopes for air rifle are only rated to sub 12 ft lbs.
The recoil from a spring powered rifle can be more destructive than most centrefire rifles!!!

This is because it has a two way recoil.
Backwards when the piston is moving forwards (thanks to Mr Newton!) and the suddenly forwards when the piston hits the end of the compression chamber.....and then probably backwards again when the piston stops rebounding backwards!!!!!! All in all this can amount to a very destructive force on something a delicate as a scope!!!

If it is not spring powered...then ignore this!!

Sceondly, I thought France had much stricter laws on shooting birds with air rifles...... ie NO WAY!!! But I could be wrong

it's in a friends barn. And there's no way you can go around shooting there using a 12 bore. And nobody will ever know.

Apart from anyone who reads this!!!!
Agreed it is the right tool for the job......although check that 5mm holes in the walls of the barn won't be a problem!!!
Also surely a slightly less powerfull air rifle would be better (not often you say that) an FAC rifle is a bit overkill for indoor shooting, unless it is a very big barn!!!

They're in the roof of the barn and it's a big barn. And I agree that my rifle is a bit over the top for the job. But it's the only one I have.

bait them down with corn maybe ? allow for the different ballistic curve if shooting up rather than flat

Anything by Hawke or AGS should be thrown away.

Sweeping statement, I have a Hawke Titanium on my .222 and it is a good as gold, never had a shift in zero and no shift in zero with the mag neither. Good clear glass and it accounts for food and vermin day and night.

Don`t think a Leup on a B2 would be the way to go either

I use to have probloems with my scope but i found the best way to fix it was patience, it took me about a month to get my scope dead on now its perfect every shot 6 months later
