I built a sniper tnt cannon that should theoretically shoot a tnt at a speed of about mach 30 or above, or over 11,000 blocks per second. I know that it should shoot this fast because i made an earlier model that shot at about mach 12, or 4500 blocks per second, and i copied the old model and close to tripled the amount of tnt that is used to launch it in the new model. The old model that shot at mach 12 worked perfectly fine, but with the newer model i am having some issues, in theory everything should work fine, but the tnt that is shot out for some reason just seems to stop after going about 20-30 blocks. This problem has nothing to do with chunk loading, I made sure the whole cannon and thousands of blocks in front of it were all rendered chunks. Could this issue have something to do with the physics engine?

If you would like i will send a copy of the world so you can test out the cannon yourself and try to see what the issue is.

Do not try to comment on this post if you do not understand what I am talking about and are not educated on how both tnt cannons and the physics engine work. I got an old issue resolved by a mod because he had no idea what i was talking about and was confused, i explained everything perfectly but he just simply did not understand the mechanics of tnt cannons and the physics engine so he was confused and resolved the issue.
