I'm looking to do a WW2 shoot with one of my (16 inch barrel) Thompsons, what's the trajectory like at 100 & 200 yards?

Can you say "drop like a rock"?

I don't have the chart in front of me but if I recall the .45 ACP drops like a foot at 100 and around three feet at 200 yards. The .45 with its large, unstreamlined, slow moving heavy bullet is far better for shorter ranges than for longer ones. Its simple physics at work and the .45 does not have physics on its side.

If you could post the graph I would appreciate it.
I just p/u a CX4 .45 and sighted it in for 25yrds and would like to see if I need to take it out further.
Thanks

They don't call guns that shoot .45 ACP "pumpkin tossers" for nothing.

Search engines are your friends. Type in ".45 trajectory chart"  and you get all sorts of stuff:

I don't think there is a simple answer to your question.  There are so many variables you are best off taking your gun out and shooting it.

But again, .45 was never meant to be a long range weapon. Up close and personal...and the Tommy gun...A trench sweeper....again, up close and personal.

230 grain bullet going 950 fps will drop around 5 ft at 200 yds

I took the gun out today, S/A 16" M1 Thompson. She shot pretty straight till 100. At 100 I needed to aim about 4-5 inches high, at 200 yards, I had to use the top of the sight and aim about 4 inches high. It was a lotta fun and a cool learning experience. Also noted I ran 150rds thru it without a hiccup :)
