not on esterigon blue. These tubes are special and I made only a few of them for justGG
Hi, is it A different steel used on 'solid 18650' tubes ? ? I'm interested in knowing a bit more if so, please.
While i found it very light, not as far the feeling of an alu ggts with telescope, i tought its only because their thinner construction with inner 'ring', wich is - as always - a brilliant and 'so GG' solution.
Now these tubes are used as 'blank experiment tubes' for engravings, plating and polishing (i know, i'll go to hell

) i find the surfaces and grain of the metal does not respond totally like an Ithaka, Penelope or jGG (as a multi-recidivist, one of my Ithaka is vertically satin finished, wich match well the new brass to say the least ...)
