I got mine from Baker first week of this month (i'm the OP)
Cleaned barrel,degassed,set regulator at 1.8k and three turns in on the hammer spring.
I got about 350 pellets through it.
Today was very still outside and shot it at 50 yards quite a bit.With JSB 18.13g pellets five,five shot groups averaged .319 inches.
15.89g JSBs averaged .390,Air Arms 16g .497.
The heavy JSBs are doing 846fps ,the 15.89 887fps.
The gun is an absolute tackdriver,only thing is the probe orings are getting a bit chewed up and i ordered 100 from The Oring store.(gun came with a couple of spares).
I forgot to add ,distance was 50 yards.The gun and i were having a good day.
Today i was averaging just under a half inch,then again it was a bit breezy.
