A 12 x12 by 8 x 57J sounds very appealing for a ramble around the club for birds, vermin, pigs, and game.. A claw mounted scope seems right.

How much would such a rifle weigh?

Saw one by Simson and Sodia.Are these quality drillings?

What would be the ideal combo for about 7-8 pounds without scope? What would a 16x16 by 7mm weigh?

Sorry, but I know little about drillings.
