I’ve been loading TSS for several years. This spring I’m using two 20g guns. 870 compact and an ATI O/U. Both will put 350+ pellets in 10” Circle at 40. Loads are 1 5/8 oz of #9.

What loads are you all running?

Have you tested different number and depth of slits in your wad? Make any difference in pattern or POI?

Pretty much the same load a you and slits left closed. Avg around 370 out of Mossy youth 20 pump and Indian creek 555

I am shooting a Wby 459 and putting up around 300 in the 10 and 250 (can't remember for sure) in the 20".
That is with a 1 5/8 oz #9 load

Several gun/choke combos but all put 300-360 conistantly in the 10” and 500+ total in the 20”.
I’ve tried a few different loads but reloaders lil hammer has been most constant across the the board

Lil Hammer and Big Stubby XL both have really put up unbelievable numbers for me. I may check my zeros this week if we get some dryer weather.
