Havent been here for some time, but now Iam back
Tested my 850 to day. Havent used it for over a year as I have to many other guns to use (and so little time).
It still shots best with H&N FTT (15,7 grn???).
The velocity was:
H&N FTT ave 613 fts.
JSB Exact 16 grn ave 606 fts.
Logun Penetrator 20,5 grn ave 546 fts.
The temp here was 16 C (ca 62 F) and some rain.
The gun has an energy of aprox 13,5 fpe (19 Joule). Not bad for a gun that is suposed to give a max 16 joule.
To morrow it is going to be sunny and ca 23 C. Iam looking forward testing the gun over the chrony at this temp.
Hopefully we will get even higher temps this summer (remember this is Norway).
Have a nice day.
