Sighting In

[Al7mm]

I sighted in my Browning semi-auto 7mm Rem Mag. at 50 yards with 1 inch groups using a Leupold 2-7X scope & Winchester 175 gr Powerpoint bullets. Went out today & took some shots at 100 yards and was surprised to shoot dead on bullseye at 100yds. This time I was using Winchester 150 grain Powerpoints.
I was expecting 3 inches high. Any idea why ? ....ie. I can't be dead on at 50 & 100 yards.
Thx Al

Newton's law maybe

You shot different loads at 50 yards and at 100 yards,so you don't really know where the 150gr load will impact at 50 yards.

X2 try the 175gr and see where they hit at 100yards!

I tried 3 shots at 50 yards with the 150 grain & the group was 3 inches low.

Something is wrong.
They can't be three inches low at 50, and dead on at 100. Try some more.

use the ammo your going to hunt with, sight it in at 100 yards and be 2 inches high, max 3, this will give you good short and long range accuracy, 50 yards and out to 250-300 yards.

if it's target shooting, and your not hunting, then sight in at 100 yards for a bullseye
