TSS also evolves to meet the needs of their guests. Since they opened, they have changed their hours and other rules to better serve their customers.
When TSS opened, only slugs could be used with shotguns. I have a Saiga-12 with an ultra-tight fixed choke. It can't shoot slugs, so I couldn't shoot it there.
Last time we went to TSS, I said to one of the employees "It's a shame we're not allowed to shoot #00 Buck," and she replied, "You can! They just changed the rules to allow buckshot."
So now I can take the Saiga-12 to TSS, and I have no further need to go to Targetmaster.
