I'm a Gunzilla fan.
I find it works really well to minimize fouling when pushing up into the 950-950+ range.
I also find it works really well to remove lead from barrels that are prone to leading.
It's part of my recipe for a number of my high performing gun/projectile combos....my .20 Ghost and the NSA slugs that I've posted so extensively about? Gunzilla on the slugs. My Veteran Long with the 1:32 LW poly barrel that I also comment on frequently? Gunzilla on the MRDs. The .22 Grands from the Ghost that is about as good as I've got for 100 yard pellet benchrest? Gunzilla on the Grands.
If you decide to experiment with it, don't lube up a bunch of projectiles that aren't gonna be shot soon. The carrier gasses off or something, and you're left with a white waxy/messy residue. It's fine for a week or two, but a month or two and you'll want to throw out the mess rather than run them through a barrel.
Ive been working from the same 8oz bottle for 4-5 years and I bet about 1/3 of it is left still. It doesn't seem to have any issues staying a liquid in the manufacturers bottle.
