I'm brand new to posting on Bear tooth, I'm wondering if somebody might be able to help me here. I will be purchasing my very first 45-70. A Ruger #1, what my question is, is this, can I turn this gun into a legitimate 200 yd. gun for deer? I was looking at the 300 gr. Barnes original spitzer designed for the 45-70. If I start this bullet at about 2100fps and sight it in 3" high at 100yds it should only be a couple of inches low at 200 yds. Remaining velocity of this bullet at 200yds should be in the 1600fps range. Do you guys think this would be a good combination with the caveat that the gun shoots this bullet well. Now I realize that the 45-70 is no 7mm whiz bang in regards to trajectory, but do I have the right idea or is there a better answer for longer range game shooting, maybe I'm asking to much from this grand old cartridge? Any input would be much appreciated.
