I've got the 36 bobcat, and it tuned in with 30grs of Goex 3f, .015 patch, .350 R/B, T/C Bore Butter lube. With mine it seems the type of lube I used made more of a difference in the grouping. With the bore butter I didn't haft to wipe the bore hardly at all.
I've tried some Maxi Balls with and without felt wads, but haven't found a satisfactory load with those as of yet.
I also tried some Buffalo 125gr hollow point conicals. They fit the bore loosely and shot poorly.
I didn't notice any improvement when using a wad with either of these loads.
Have fun with your new rifle, you'll have a blast shooting it. :winking:
