Neither one is going to bang flop deer with lung shots etc Too slow a velocity! It comes down to hole dia and ammo availability unless you're a reloader.Dead's dead..............Harold
mikeystew, your living there in BC, I'll suggest you up your specs and go for something like the New Marlin 338, more than enough for deer and will take a grizz if it had to.
More snot for sure - but the question was put 30-30 versus 35Rem....the New Marlin 338
Ben, with 220gr Spears FP in 35 Rem you can be very, very serious, and then some.I agree, lets keep it 30/30 vs. .35 Rem., if you need more there is always the 45/70, these are all good cals. and the savy shooter/reloader can use cast bullets to better effect then jacketed, and save lots of money in the process. I'd want to try the 250gr. cast flat pt. in the .35 Rem. for serious work.
30-30. If for nothing else, just for ease of finding ammo.
