Bullet drop

[rollingrock]

Very funny here. I took my M44 to the range today and tried both 174 gr fmj and interbond pushed by 44 gr of IMR4895. At 100 meters I had to aim quite low to put the bullet right in the centre of the small target paper. So I thought at 200 meterss both types of bullet should drop somehow. But to my surprise I had to aim even lower to put the bullets on paper or to hit the gong. So that means the bullets didn't drop at all! I wish I could have tested muzzle velocity with my load, must be super hot! Both the front and the rear sight are at the lowest settings.

If your bullets were landing 8" high at 100 yards they would have already been about 16" high at 200 yards. If they were 4"" then think about 8" at 200 (no adjustment for actual drop considered).
They're dropping but the angle of flight extends beyond the initial target.

Why can't you set the rear site higher to raise the point of impact ? You said it is at the lowest setting meaning bullet will drop or am I missing something ?

iskubits, you've got it backwards. Easy to do. bearhunter

Actually he has it sort of right. Raising the rear sight will raise the point of impact. However, since the point of impact is too high already, he's going the wrong way.

: Both the front and the rear sight are at the lowest settings.

The lower your front site the higher the bullet will hit.

The higher the rear site the higher the bullet will hit.

I slipped a piece of roll pin onto the front sight post, fired a couple of rounds, filed the roll pin down, then fired another couple of rounds and filed again...finally the POI was brought to the bull's eye. Yesterday I was able to put 3 shots into 1 1/2 inch group at 100 meters with iron sight with my handloads.

But...I've found something strange. I was shooting 174 gr hornady interbond roundnose and 174 gr hornady fmj boattail. The roundnose is .312, and the fmj is .3105. I was expecting the roundnose to drop more at 100 meters with both being pushed by 44 gr of IMR4895. But to the contrary the fmjs were 2 or 3 inches lower than roundnose! So I'm assuming that my gun's bore is bigger than .311.
