I'm primarly a BB shooter and regularly fire it at 600yd targets using Swiss - Goex FFFg and Cartridge with the Lyman 457123 Postell bullet. Good groups. Best was last Summer - 5 shot group using 495gr custom BP bullet and 60gr vol of H777 ... 4" x 7.27"
using a vernier Long Range sight.
I've also tried some Rx7 and 4895 under the Postell at 600yds. Don't remember details, but if it was bad ... I would.
It's a shooter for the price. May want to consider the 38-55 barrel too.
