If you want to shoot cheap, shoot the .22..
I do mold my own for the .40 and .54 flinters...
I'm just glad I bought 5-6 boxes of the T/C Shockwaves a couple of years back so I don't need to try any new bullets...I will say this, if they work as well as the original (mushroom) Barnes and fly as flat as a 250 SST them I will be trying them after I use up my SSTs, course that might be awhile, I didn't even load the Knight last year, stuck with my flinters...
