Choked vs choke-less barrels and maxing out the power on the Anschutz 9015

Testing how the power and accuracy is effected by removing the choke and crown.. from the lothar walther barrel in my Anschutz 9015
Ive now reached the limits of the 9015 regualator...
I'm doing a few experiments to find out the maximum power the 9015 can make whilst still remaining sub12 and curiosity also got the better of me ,so it was range tested before the barrel was re crowned and fully finished. Definitely a very surprising result but i wouldn't recommend it!
Im experimenting with various slugs and had to try a choke less barrel, don't worry it has been fully finished properly now..
the slugs are the new jsb ko mk2 10.03 gn in .177
the pellets are jsb heavy 10.34gn in .177
the rifle is an Anschutz 9015 , a dedicated target air rifle
it's the first time ive been able to wind the 9015 up to its maximum power, i was surprised how nice the shot cycle was even maxed out
the barrel has remained accurate with the jsb heavies at all stages of the test, theres some very interesting characteristics with the power and accuracy of the slugs and some further testing is required
I may end up fitting the barrel into my airmaks katran as that has a larger regulated volume, however i'm really curious about the new epic2 air rifle so might wait until they are available later in the year.
