When you look at a drilling rifle barrel ( and this data ) you realize how paper thin they can be and still be accurate whith the two shotgun barrels to keep them stuff.

You can make a barrel stupidly light but at the expense of rigidity
A 7075 sleeve well fitted is extremely light and stiff.
It also conducts heat vastly better than carbon wrapping.
Carbon being very stiff and light but also a good insulator !

the barrel is comparatively lowly utilized compared to lugs though.

How do you ensure barrel and 7075 liner stay together and ensure a uniform tension/compression (which is likely to be necessary for precision) over the barrel? Heat shrink? press fit? (imagine both difficult to uniformly do over long lengths) -curiosity only

You’re back to my point made earlier. If you can’t shoot your rifle well consistently because its super lightweight requires a technique that’s difficult to replicate in different field positions then your weighting the attributes incorrectly.

Adding heavy brakes and suppressors is not something that I would or can do here. Al well balanced sporter and scope in the low 3kg range is shoot able, and able to be carried in the hand when needed.
