.257 ammo.

Mr hollowpoint and NSA seem to be reputable suppliers of .257 ammo. It seen NSA is currently out of stock so what are some other options for purchasing ammo? Any suggestions

After typing “.257 slugs” into a Google search box One of the first things to pop up was this site. https://griffinairgunammo.com/collections/257-caliber-rbt


then I checked AGN for members who’d used them and found this

Try it for yourself. Good luck to you. 
 
I apologize, I was laughing at the first gibberish response you got above. Maybe check Zan from the sponsors above, or post in the pellets, slugs and projectiles category. NSA is still filling in inventory from their move I’d imagine, so perhaps you can ask them directly when to expect .257 to be in stock.

When they are clearly to lazy to feed themselves,you throw them a bone
