I don't have a CZ, but I do have a 375H&H with a 25 inch barrel that I am planning on chopping down to 22 inches when I get around to it. The loss in velocity doesn't make all that much of a practical difference IMO at normal hunting ranges, and I've come to prefer shorter barrels which make rifles more handy.

My 9,3x62 is 19 inches for example, and I wouldn't want it any longer.
