Welcome to Nitro Express,

The CZ's can produce a lot of opinions. I have owned two conventional CZ's. Straight from the box I beleive the CZ's can all benefit from the little tender loving care of a competant Gunsmith. If your rifle feeds and extracts reliably then it is an excellent entry level DG rifle.

They can all benefit from trigger work and (I peronally beleive) any rifle above .300 calibre will benefit from correct bedding and stock re-inforcement.

The scope you have chosen is de-rigueur for DG rifles and with the #4 reticle is perfect for larger game. I have a Leupold #4 reticle in a Leupold 1-4x20 Shotgun scope on my 9.3x62. It proved ideal for large plains game up to 750kg live weight in Africa in June from ranges of 40 metres to 230 metres.

I have no knowledge of the McMillan stocks but beleive they have a good reputation for quality.

Consult a quality gunsmith in regard to bedding the rifle. Sunshine Coast gunsmiths in Qld have a lot of experience with CZ's and DG calibres. Other forum members maybe able to recommend gunsmiths in the southern states.

IMHO you have an excellent rifle. Get it sorted if required and then shoot and enjoy it.
