RE: 30-30 what grain to use
I USe the 150gr Nosler BAlistic tips when i had a 30/30 I Now just use a .243 for deer hunting, out to a range of 250 yards. Ive had them knock back 3 feet on inpact. A 100Gr sierra with 40 grains of IMR4350 has taken down deer, bore, and i have taken a Carabou out at 200 yards. Id never need a Big Cal gun, because the only thing i cant shoot with my low recoil .243 is a moose or a grizz. Plus having had 5 surgeries because of a broken back, I couldnt shoot one anyways lol.
Your 30/30 really doesnt have the velosity to hunt out more than 150 yards. and the drop is intense.
