Ream 9mm Chamber to load 147's longer?

Is it worth it? Cost is very low to get it done, but is it worth it to have more flexibility with longer 147 gr bullets? Certainly the nature if the 9mm case does not like bullets seated deeply. This would allow a higher percentage to pass the case gauge. I'm currently getting about 5% failure.

Currently I'm loading at 1.098 due to the profile of the Blue Bullets. I'd like to go out to 1.2-1.3.

I reamed my CZ barrels so that I could max out the OAL (1.155") with the Bear Creek 124g RN which has a fat shoulder that starts early. Now my CZ's can take any ammo I make for them as long as they fit in the magazines.
