Shooting TSS 9's. Already tried Truglo and Indian creek. 300 in the ten is the best I've got.
Thanks
Which TSS 9s? Federal, Browning, Apex, Boss, etc.? Most 20 gauge TSS 9 loads are around 560 pellets. You're well over 50% in the 10" so unless you're just obsessing over sheer numbers, I'd be more interested in how even that 10 really is and how well dispersed your 20" is if I were you. Just a thought...
My hand loads. Big XL 1 5/8 All my other guns get 350+ just trying to get it a little better.
