long range pellet testing a custom AA s200 CZ barrel in the Anschutz 9015

What is the best competition pellet? testing the upgraded cz barrel in the Anschutz 9015
today i test the jsb exact heavy against the air arms diablo field and H&N 8 and baracuda ft in both 4.50 and 4.51 head sizes
groups are shot at 50metres in a strong wind to compare wind drifts with the idea to push them out to over 100yards
the cz barrel ran the H&N pellets really well and definitely an improvement over the factory anschutz barrel. the twist rate is also very similar to that of the walther barrel in the air arms xti50 that thrashed the 9015 at 100 yards last week
