Catfish,
I have had the same luck with the calhoon bullets, That being said, what i would do was to keep changing the loads untill i got the results i was looking for, But with a little time i got all my guns warking good. My 17 rem is a real tack driver with the calhoon bullets. works good on yotes never a pass through and haven't had any run off. I'm pretty picky about my loads, If they arn't right i can them right away. Been this way for 56 years and don't want to start being slack now. Have a good day catfish.
Trotterlg, No apology necessary, It is hard to find the 20 cal on his web site. Have a good day
