Re: Savage 308 /175 SMK - Bullet Drop Question

Thanks for the info between all of us we'll get you straight.
If you can I suggest doing the following.

1. Verify/rezero 200 yard zero.

2. Move a target to 300-400 yds (verified yds) and shoot it using the same aim point ( no holdover) your rounds should be 8" +- at 300 or 24"+- at 400 below the aiming point. Since you don't have a chrono this will let us get a decent estimate of your muzzle velocity.

SBruce I was wondering about the scope set on 20x if that was the problem, this is my first time shooting at 600yds. trying to figure out how the scope works the Mil Dots.


thanks for the info
You're welcome, we'll get you figured out.

If 20X is exactly 3 IPHY, then 16.5X will get you really close to 3.6 IPHY (or 1 mil) Just try it at the range against paper to confirm.

You don't really need a chrono, but if you don't use one; you will need to know where you are hitting at a few different distances in order for someone to figure an approximate velocity for you.

These guys could be on to something with checking the power to see where your mil dots are calibrated. Pretty simple to do if you have 100 yards to work with or a collimator (bore sighter).

Yea, it works. I've got a 8.5-25 with the TMR. I personally don't like to think of things in mils, and would rather use IPHY. If I turn the power down to 15X, the marks that were every 1/2 mil are now every 3 IPHY. Then I can visuallize a 1/3 mark or 1 IPHY pretty easily.

Not Sbruce, but IPHY is Inches Per Hundred Yards. As far as Mil dots go here is some light reading for you. Should help get a better understanding of it.
