Located 30 miles south of Seattle, about 600' abovesea level, temp averages high 30's to mid 40's. I have never had any problems with the pyrodex rs and #11 so I really hesitate to make such drastic changes, also I have never shot triple 7 pellets out of my knight or any pellets for that matter. The season is only open until Dec 15 so I need to make somethig happen quick!! Thanks, HF41
