Iron sights - Trigger45 - 03-14-2020
Ive recently acquired a 6.5 Grendel and I know opticss are all the rage, but currently as Im working on a .308 win right now, I ordered a set of open sights.
The question is where would you sight it in at? 25 yards or 50? And what yardages would the bullet cross the line of sight?

If you plug in your info into the ballistics calculator it will give you a pretty good idea of what will happen.

25 yards.

Trigger,
You can shoot for zero at either 25 or 50, doesn't really matter.
How you go about it will depend on what type of zero you want;
1. A standard zero, e.g. 100yds for known-distance and long range shooting.
2. Point-blank-range zero (PBR) for maximum opportunity to hit a known diameter/kill zone (without adjusting for range) - 'Point and shoot' for hunting.
You can use JBM ballistics (online) to see where the bullet will impact at 25 or 50 relative to some other standard zero, like 100yds. If you set it for 1yd increments this will also tell you where the bullet crosses the line of sight.
You can use JBM ballistics to get your PBR. Enter the diameter of the kill zone and it will tell you where the bullet will print at 25 and 50. You then zero the gun at one of these ranges according to where the bullets should print.
For both you will need to enter the bullet and velocity.

I'm 2" low at 220
I'm 4.5" low at 250

It really depends on how far you feel comfortable shooting .I would start at 25yrds. Then I would go to 50 yards. I have my Winchester 94 sighted at 50 yards same with my Winchester 9422. They both have skinner peeps on them. If I was shooting at game ,I wouldnt be comfortable much past 50 yards W/iron sights. But,that is me.Ive seen my dad shoot deer past 100 yards with factory iron sites with the Winn 94. One shot kills.
