Taipan Veteran Standard 25 data and more..

Hello colleagues,
I am interested in the following data about Taipan Veteran Standard .25:
1. Rifle length?
2. Gun weight?
3. Barrel length? 460mm?
4. Twist rate and right or left twist?
5. Choke or Not is barrel?

Thanks in advance!

Does anyone know where I can get the gauge data - height and width and the weight of the game (rabbits, pheasants, etc.)?
/ My thought is for my facilitation in targeting ... The Optics will be Athlon Argos BTR 6-24x50 FFP /
Greetings.
