The hard loading is with TC super glides and with barnes bullets, no difference.
Most omega users will use the crush rib sabots. They also have learned to use JB Bore paste 60 passes minimum to help smooth out the tc bores. It really helps these guys a lot with loading. One guy would basically have to beat even the crush rib sabots down the bore even on a clean barrel. The jb bore paste is something you really should look into.
BH209 cleans up super easy for me, even in my non bore coated barrels.
When you go to clean up BH209, run at least 2 to 3 dry patches down the bore first, this collects and removes the loose fouling that normally would turn to sludge if you did not dry swab. It makes a huge difference.
