I shoot the 270 Speer Gold Dot at about 2050 fps in my Winchester 94 BB. Have killed one caribou with it, at about 65 yards. The bullet seemed to work just fine
.
I use H 335 for all bullet weights, and can easily run 300 gr bullets well over 2100 fps out of a 20" barrel.
I sight in 3" high at 100 yards, for about a 175 yard zero. Mine carries a 3X Leupold, which seems to be nearly perfect for it.
Happy hunting,
DN
