Hi All,
Well just got it back this morning with the power reset by the importer, apparently they had a delay waiting for information from the manufacturer, but I had a phone call Wed to say it was being done that afternoon & a call from the shop Fri to say it was back.
Straight off it feels a totally different rifle to shoot, there is a slightly more pronounced recoil kick, but not to the extent of feeling at all harsh, very similar to my old TX200,
but god what a difference in perfomance !
I put 5 through the chrono to get a speed for "chairgun" which said increase zero range from 21yds to 24.5yds for the best PBR. First group was still 4" high from the old zero!
One very interesting fact is that at the lower power it seemed quite pellet fussy with only the Marksman no3 giving consistant groups, now every pellet is grouping much tighter, I think the Marksman has still just got it, but the H+N FTT is mighty close. Also the 2 heavy Bisley pellets have halved the holdover required. PBR is now 6-27yds
Muzzle velocity is pretty much 60 fps better across the board and chrono figures are now at a level that require very close monitoring, rangeing from 11.4lbft - 11.8lbft, so it may yet need to be turned back down a bit.
Can't wait to take it out in the fields & woods tomorrow.

Forgot to add, when weighed the Bsa Pylarm is actuly 21.2 grains not the 18.6grain as stated on the tin so the old muzzle energy raised from 8.2lbft to 9.3 lbft.
