Sight in a rifle? Help?

Postby bassman8990 » Sun Nov 03, 2013 4:01 pm

Hey guys I'm new to this form, I have a question ab sighting in a rifle. I have a 270 & a 30-30 that I shoot 150 gr soft points out of both
I sighted them in a couple days at 50 yards, I was limited on the area I had but I sighted them both 1in high @ 50 yards. Can someone tell me what they will be at out to 100,150 & 200 yards as far as point of aim?

Thanks!!!

Thanks for your answer! I sighted them in at half to 1 inch high at 50 yards. So basically as long
As I stay with in the 200 yard range with the 270 & the 150 yard range with the 30-30 at 1in high
@ 50 yards I should be good? Am I thinking correctly?

Generally, 2 inches high @ 100 yards gets most people with most deer rifles a decent point blank range. With the 30-30 it gets you somewhere past 150 yards.

My advice is to download PointBlank software (it's free) from the web and crank some numbers. Things like Ballistic Coefficient, muzzle velocity, etc can be found on the ammo mfg's website. You can guess and fudge a little here and there, but the important thing is that you get a good representation of how the bullet flies below, then above and back below the line of sight as it travels.
