Sumatra 2500 Carbine 22cal Pellet Testing

I was doing a somewhat scientific Accuracy test with different pellets through my Sumatra .22 today. This will be my settings for plinking and target shooting.
I wanted to share this in case it helps anyone out.
Conditions
25Yards rested on pillow in window-sill
Sumatra 22 cal (Bought New June 2015)
No noise reducers/ldc
Power Setting First Click and taped down (lowest power).
Velocities ... Wish I had a Chrony !!!!
Trigger screw adjusted near sear break point (0.5 turn).
5mph intermittent wind and misting rain (Shooting out the window today...)
Each Pellet tested got 6 rounds with 3000psi/200bar topped off.
Left to Right : H&N Barracuda Match 21.14gr, H&N Hunter Extreme 19.09gr, Beeman Kodiak 21.14gr, JSB Jumbo Monster 25.39gr
As can be seen from the target photos (Top row) the H&N's were the only ones that performed well. I suspected from other shooting I've done that the JSBs might not shoot well but I expected the Beemans to be a bit better. I put in some notes where there might have been a flyer and what the measurement would be if I only counted the best 5. I would not draw any statistical conclusions from this, its just one sample of 6 shots with one shooter!
the second row I decided to rest and re-test the JSBs and the Beemans. the logic here was that maybe toward the end of the testing on row #1 that I was getting tired. As you can see I think I exonerated the Beemans but the JSBs are shooting even worse.
I will say that the JSBs have noticeable skirt damage on them and were even hard to load because of this. The skirts on these come out to a feather edge so they seem prone to this damage.
I'll post more if I notice anything else.

Sorry for the late reply, summer is hectic with kids! I haven't gotten to the range yet to test the sumatra on full power. I shot a couple of .22 hollowpoints in the 35-45 grain range in the basement with a heavy backstop but my setup didn't lend itself to testing groups at a decent range.

You should try out the Eun Jin 28 & 32g pellets. Korean airguns seem to really like Korean pellets.
