Grandson and I sighted in out MLs yesterday. I have never seen such bad fouling . I've normally been able to get 12 to 20 shots with the Encore, without significant fouling. Yesterday, after 8 shots, the crud ring was so bad, I could not seat the bullet on the powder. [double tap discharge] I was shooting cci muzzle loader primers[first time using these], White hot powder and PR bullets. Any ideas out the as to why the bad fouling? Wade in! Cheers, Jim
