I shoot a T/C Thunderhawk, which I belive is the predecesor to the black diamond. I love that gun. I to shoot with #11's, but by choice. I don't see the need for shotgun primers, since I've never had a misfire with an in-line. I used to shoot a Disc, but that's one of the reasons I got rid of it. So my money goes to the black diamond first, or maybe the American Knight rifle.

As for inlines i have a knight mk85 and a 45 superdisc .The mk85 i bought in 1991 and got the 45 super disc in 01. The knight mk 85 is my favorite ,last year i put the disc extreme kit in it so i could use the 209 primers and i really like that for bad weather. I have tried many blackpowder guns and the mk85 is the gun for me. I use 90 to 120 grains of loose powder,hornady 45 cal. .451 200gr hp/xtp bullets with the black highpressure sabots for deer and if i am going for hogs only i use the 300gr xtp with 120 grains. I have used this load in the mk85 for over 10 years and have very good luck,if the game does run more than ten yards it leaves a blood trail a blind man could follow,but most hit the ground hard.As for the 45super disc it was a super mistake,i wouldn't have another if you was to give it to me, but thats just me.
