I have several containers of 3 f Trip 7 to use with my T/C Hawken .45. So i load 40 gr n a wad of cotton ball, lube up some flannel patch material. Put my RB in the bore cut excess off n run it on down til it seats. Put a small pistol primer in my Accua-spark. Settled on my bag n shot. Sweet , run alcohol patch down bore n a dry one. Bump the load up to 50 gr. I shoot nice, do my clean on bore. Bump load up to 55 gr, feel little recoil, clean bore. Bump to 60 gr has some thump run patch down bore uggg. I can't believe i have crud ring started. Shoot once more n ring is worse even though i run wet patch down it. I stopped my shooting session. Came inside n cleaned it using Dawn dish detergent. So 40-50-55 all is ok. Hit 60 gr n cha ching crud ring. Now is it the 60 gr or the cotton ball wad or the small pistol primer causing it or the total combo. I only have a half lb of 3 f Goex for my 2 Flintlocks. That is why i got the trip 7 as the perc. will ignite it
