GT is considered to be quality ammo and is non-corrosive. Check some of the AK forums and Surplusrifle forum. That said I clean my guns as if ALL ammo is corrosive.
From surplusrifle forum: "Get golden tiger if you can, I really like that. I also use most any wolf or brown/silver/grey/pink/lavender bear ammo"
" +1 Golden Tiger "
" I wanted to mention that my Wasr will keep 10 rds of Golden Tiger in the black at 100yds on an SR-1 target."
" its a great shooter with golden tiger! ts200 peep and fine front post. " SKS
