Alright I have a Uncle Henry 22 magnum with a scope mounted
1.5 inch's center to bore if I sight it in at 25 yards how high will it be at 75 yards with a 30 grain bullet and how high with a 40 grain bullet.The reason I ask is because I sighted at 25 yards with 30 grain bullet and am missing raccoons at 75 yards I think I'am
shoot over them.
Thanks

Do a Google search for a free online ballistic calculator and you can work up any numbers you need. Hornady, Winchester, Federal, handloader.com and many more have one.

I use Ballistic AE.

I'm not sure what brand you're shooting so I assumed CCI's 30 gr TNT HP for the 30 gr load with a published MV of 2,200 fps.

With a 1.5" sight height and a 25 yard zero:

35 = .5"
45 = .8"
55 = 1.1"
65 = 1.2"
75 = 1.2"
85 = 1.1"
95 = .8"
105 = .3"
(110 = 0")
115 = -.3"
125 = -1.2"
135 = -2.3"
145 = -3.6"
(it goes subsonic at 151 yards)
155 = -5.2"

I assumed CCI's 40 gr Maxi-Mag HP for the 40 gr load with a published MV of 1910 fps:

With a 1.5" sight height and a 25 yard zero:

35 = .4"
45 = .7"
55 = .9"
65 = .9"
75 = .8"
85 = .5"
95 = 0"
105 = -.6"
115 = -1.5"
125 = -2.6"
135 = -3.9"
145 = -5.4"
(it goes subsonic at 155 yards)
155 = -7.2"

------

It's a little counter intuitive compared to most centerfire rifles, but out to 100 yards or so, the heavier, slower, 40 grain load is actually a little flatter shooting with a scoped rifle. That's due to the line of departure needed for a 25 yard zero. Since the 40 grain bullet is slower and drops more, it does not require as great an angle of departure to reach zero at 25 yards, and as a result the mid range trajectory isn't quite as high as it is with the faster 30 grain load. But, there's no free lunch and the 40 grain load will drop faster past 100 yards.

22 mag's worked great in my Ruger single six for ground squirrel at 30-40 yards on the levies next to the gravel roads in the back country, when I was younger.

I sight most of my rifles in at 25 yards, no matter what caliber, then log the info for 50 and 100yard targets at the range. I liked a 75 yard zero in the rifle I had years ago but I traded it for a old Savage auto that I shot quite well on an outing.

Good shooting.

You can speculate, cogitate, estimate & calculate ... or you can just shoot at a bullseye at 25, 50 and 75 yds and know for sure.

You'd be surprised how accurate modern ballistic apps are. Provided you're putting in good data, (velocity, BC and sight height) the math is pretty much dead on.

That said, I agree at 100 yards or less with an accurate .22 LR or .22 Mag it's easy enough to develop the results empirically - or verify the results of the ballistic app.

With centerfire rifles at long ranges an app, combined with good chronograph data from your particular load and rifle will get you on the paper or plate with the first shot - assuming you lase the range and the dope the wind right, and a ballistic app takes a fair amount of the guess work out of that as well.

Thanks that helps a lot
