I am shooting an Omega, with the Nikon scope and I am zeroed at 100 yards using 3 50grn 777 pellets. If I was to drop down to 2 pellets, how would that affect my 100 yard zero?

You bet it should! You would be changing from 150 grains of powder to 100 grains. So the velocity would be reduced and the arc of the bullet would be more dramatic.

Make sure which T7 pellets you are shooting, there are the normal 50 grain pellets and the new 60 grain pellets...

This page will show the differences...

I am using the .50 cal, 50 grain pellets. I know it would , was wondering if anyone had any data thanks.

I can not really help you as I do not shoot pellets. The T7 site should have some ballistic numbers. But I can not say I have ever looked.

Here is a balastic chart that gives pretty close to what you are asking. Of course it is with powerbelts, but compares the trajectory of different size bullets with 100 and 150 gr of 777 pellets.

That said, I have a gun that I shot at 100 yards with 100 gr and then right after shot with 95 gr of powder. The 95 gr load consistently hit HIGHER at 100 yards than the 100 gr load. So while you can look at charts for a general idea, you will have to shoot your specific gun to get the actual results.

Thank you, I planned on hitting the range and re zeroing the rifle for 2 50 grain pellets. I rarely have a shot past 100 yards, and the 3 50grain pellet load is too hot, if you don't hit bone you get no expansion at short range.

Bullets moving so fast, it doesn't expand????????????

yep that's normal, if ya need to know why study ballistics

I know why, but there are a lot of people out there that just assume if you use a smaller load, you hit lower. You can't make that assumption
