Thanks for the suggestions and advice Rockhound. I am loving my .690! I think your right about it "breaking in" as mine just got better and better. Mine shot it's best patterns after a deep cleaning, then a couple of shots, dry brushing in between the shots. Thanks for recommending this choke to me, it shoots very even nice patterns with everything I've tried so far. Will post up some patterns after season ends( going to test some more loads) Have a lot of pics to post yet but need my kid to show me how and he is still busy with school, lol!
