6mm (or .22) GT in a Superlite could be fun...
I have the same convenience factors to do dasher (brass, dies, access to a reamer) for the superlite.
Have mag follower cut and just need to stick a spacer in there to get it to feed right. Already ran it with some cardboard back there works great. And the super lite mags are really simple shapes. Single stack helps.
Given the weight of the rifle, the dashers and GT’s and maybe a 22 creed are a good fit.
I’ll probably go with an 18” dasher barrel on this build.
