Okay, my handloaded 200gr WFNGC from my 6" Fusion longslide:
8.3gr LS, CCI300 primer, 1.250" = 1256fps average
They tend to run faster than the 200gr XTP's do with the same charge (and with slightly lower pressure due to the shorter bullet length).
the 200gr XTP data: (over-book, do YOUR OWN workups please)
8.5gr LS 1253fps average
8.8ggr LS 1241fps average
9.0gr LS 1292fps average
9.2gr LS 1308fps average
9.4gr LS 1325fps average
I think that your WFNGC would be DEVASTATING on deer in the 1200-1275fps range... no need to push as high as I've gone here (with the XTP)... I am just showing you for reference. In fact, I think 8.2gr is a FINE load for deer.
