gdong,
the backing up is not caused by the bore. That is really the only point. A trumpet is complex and if one is not willing to dig pretty deep, it is best to just believe that the designers know more than you do!

There are some pretty large bore horns being used as lead instruments and some pretty small bore horns being used symphonically. Indy car tires do not make a Geo go faster.

gdong, I think your horns are probably .468 and .470, .700 is closer to a tuba bore size!

I've found that bore size is basically irrelevant in terms of how an instrument plays. Leadpipe tapers and bell flares factor in much more than bore size.

I agree.

My Conn 5A cornet has a .485 bore and I use a Bach 7 (no letter) mouthpiece on it.

If I want to blast a ton of air into it, it will gladly take all the air I can give it and give a huge sound in response.

*But*, if I play very softly, just as softly as I can with minimal air flow, the Conn 5A gives a gentle, beautiful tone that is close to soundling like a very mellow flugelhorn on low ballads.

The softer I play, the less air flow I use, the sweeter that huge bore sounds, even up to a soft D above High C.
