Somewhere in the back of my mind I was thinking that APP's Shockeys Gold is the same as Goex Pinnacle. I may be wrong but didn't APP make the Compressed charges for Pinnacle? Anyway if you want to use the same powder in your sidelocks and inlines then Blackhorn is out . I would go with triple 7. I use it in both and never had a problem with a hangfire using either a remington #11 cap or winchester magnum cap. If you don't want to swab after every shot then it's either order Goex or buy Shockeys Gold. AH decisions decisions!! Better yet order some of each and have all kinds of fun messing around.
