Taipan Veteran Standard 25 data?

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!

PP. 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 6-24×50 FFP /

Greetings.
