Defender the 35 Remington is easily a 200 yard deer cartridge. Granted some of the anemic ammo that is out there wouldn't make it but the Hornady leverevolution ammo isn't one of them.
Sighted in 3 inches high at 100 yards will put you back to zero at about 180 yards and about 1.5-2 inches low at 200 yards and about 7-9 inches low at 250 yards. and still have about 1150 foot pounds of kinetic energy at 250 yards.
Going past 200 yards with a .35 remington can become tedious. I think that you'd be better off with the 30-30 for those longer shots. JMO
I really don't know where you guys are coming up with the 35 Remington not being a good 200 yard cartridge but the 30-30 is????????
