Well, I just spent an hour running the powdered graphite thru it, and another 10 min running the H335. There is a considerable difference in how much leaked thru, about 80% less. The one thing i did notice is, the H335 starts off pulling easy, then the pulls get harder. Im guessing thats the powder making its way in-between the 2 surfaces. If this is normal then I'm fine with that! Im used to running extruded powders, this is my first time using something so fine.
Lock and load, the zombies (democrats) are coming (to take your guns)!
