On H or I reloads, there is some differences in the nozzles.

H268 has a larger hole dia. than a H210.

Any thing bad going to happen If the H268 nozzle is used in
a H210?

Boy, I would *not* risk it. So you know, the H268 has a different, special aft closure -- the H268 nozzle won't physically fit in a regular 29mm closure.

That said, you could (theoretically) use the H268 closure and nozzle underneath an H210 -- but there is no way I'd do it. There may also be different fiber washers, liners, etc. between the reloads that would conspire to make this a bad choice. This is also not a "certified" load any more.

After building many motors from 38mm to 6" diameter and understanding those Motors and how they perform, what you are doing is taking a "specific" sized nozzle that has been run and tested to give pressure for a given propellant. The 2 motors have different convergences and divergences as well as most importantly different nozzle throat sizes. By switching them you could end up with an instant BOOM!!! and the other a worthless no thrust generating fizzle. That is some of the biggest issues.

Enough said. As I thought.
