yeah i have a adjustable gas block that works very well.
as far as reloading goes, before i got my gas block adjusted properly, I DID have a bunch of fouling on the brass but always wet tumbled with stainless pin. but since my gas block is now correctly set barley get and carbon on them now, but that is also dependent on the powder. with the vv540 and the h4895 there is very little but with leverevolution i do get quite a bit more, that stuff is dirty.
