Well i took the training class at Thunder valley with Tom and he tought me to shoot out to 1200. Hitting targets out to 900 was no problem with a 7-10 mph cross wind. 1k to 1200 was a bit more tricky but easily doable. Most of the targets were 12x12 and some were 6x9 head cut-outs. lol
Also i was gettin 2620 ft/sec out of factory 123 a-max ammo out of a 24" tube.
Also took out my .223 gun and shot to 1k. i was getting 2900 ft/sec with wc844 and a 69 grain smk.
