Hoping Bob sees this and charts these numbers for me :-)

858cc fill 2150 down to 1550
30 shots of .FX Boss 46.3 grain pellets
933 947 978 946 954 2050psi
918 942 983 953 960 2000psi
982 960 948 936 960 1875psi
959 958 964 956 949 1725psi
936 936 949 942 937 1650psi
945 931 920 920 914 1550psi

AND this barrel really likes these pellets. Hoping the JSB 45 grain are as good.
Made a mold that throws them 109.5 grains which it likes as well. Ran out of them will cast more for the
AIRFT shoot next weekend.

Hoping to approach Whitewolf Wolverine accuracy! :-)

Pretty big ES, but the average is 947 fps (92.3 FPE) x 30 = 2768 FPE....

Air used is 858 / 16.4 = 52.3 CI with a drop of 600 psi (41.4 bar) x 52.3 = 2164 CI....

Efficiency is 2768 / 2164 = 1.28 FPE/CI which is excellent....

Any idea why the velocity is jumping around between 918 and 983 (7%) just 2 shots apart?....

Bob

Yes, we're very pleased with the barrel design.... nothing but good comments so far, with the JSBs and my 70 gr. BBTs.... I plan on doing a regulated .30 cal repeater this winter myself....

When they were first availible I got mine from Sean. Dont remember the exact cost. Wasnt cheap but well worth the 1MOA from the Condor platform. IMHO.

Nope, not Crosman based, nor European.... Working with a friend from south of the border on this project.... Uses Lloyd's converted MRod magazines, though, and a 22CI tank reg'd to 2000 psi.... That's all I can say for now.... :mrgreen:
