Who's shooting 147g out of a CZ?

Can't comment on CZs but in my 9mm 1911 I had the throat tapered fairly long - to match a dummy cartridge I sent with the barrel - and shooting shorter loads doesn't seem to have any effect on the accuracy.

 

However, they are all individuals !!!

I've never seen accuracy degradation after reaming the throat, even when I did it with a drill bit :devil:

 

No apparent effects to leading or barrel life or fps as well? Was wondering about initial impact with the grooves at higher velocity and gas blow by, etc..

I load Xtreme 147s in various CZ/Tanfoglio. My P09 being the most picky. Requires me to load the shortest OAL from all others. I load 3.0gr of TG @ 1.10". It works on all my CZs/Tanfoglio no problem. 

I think your OAL is fine. I've been loading SNS 147s over 3.0gr of N320 at 1.100" like MrRick with no signs of overpressure. I was nervous at first too but it is perfectly fine.
