omega and bm3 ballistics question

[bramer1295]

I am going to shoot 295 powerbelts and 85 or 90 grains of bm3 and sight in at 50 yards.   How high at 50 yards will I have to sight in to be on at 100.  

If I am dead on at 100 how low will I be at 150.  

I used to know the ballistics when I shot triple 7 but I would assume the ballistics will be different with the bm 3.

Thanks for your help.

Some of that is going to be depending on what rifle you are using. I found with my Omega shooting 90gr. BM3 and a 300gr. sabot/bullet I was about one and one half inches high at 50 yards and less than a half inch high at 100 yards. I never checked beyond that as I don't shoot any farther than 100 yards.

bramer1295, the best information I can give you is to sight in your gun at 50 yards. Then move the target to 100 and then to 150 and see where you are at. I set my muzzleloader up to shoot 1 inch high at 100 yards. My gun is then set up to 1 inch low at 150 yards. I hold dead on from 0 to 150.

I basically do the same as Redhawk when hunting with the rifle within an inch of POI I don't worry about the slight difference and hold dead on. Usually I am so pumped when and elk presents itself I doubt I can hold that close anyway or worry about holding off center and inch.
