Don't give up on your Tempest - there are plenty of good results being displayed here on the BBS that have been shot with the Wobbly Tempest so yours is not typical and just needs some attention.

Your next visit to RMTC can include some time with my .177 Tempest - no problem getting that one zeroed-in on the 10 meter target - come and try it for yourself.

Don't go all wobbly with your Tempest
