I bought some last year and my initial reaction was very positive. My knight liked it and i got pretty accuracy using it. I'm more of a hunter then shooter so when I went for a reload it had formed a pretty good clump in my reload tubes. If you shake it it will crumble pretty easily but I never want to have tell a deer I just missed to hold still while I shake a reload tube. I would pick up what looked like frost in the last 2 to 3 inches in my barrel after about 6-7 shots. My reload would easily break thru the frost looking substance in the barrel so it was'nt a problem. My gun cleaned up very easily after shooting. I have 3 bottles that I bought last year that have never been opened but I can tell the powder is basically in a big clump. Like I said it breaks up easy enough. I may go back one day to it but I'm back with t7 for now.If you really want to try it then let me know and I will make you a great deal on 2 and 1/4 bottles.
