I’ve been trying Tubb Dust in a Remington 7mm Rem Mag that Is accurate as all get out but moderately copper fouls. Using 65.4 grains of IMR 4831, 140 grain Ballistic Tips and the directed amount of Tubb Dust (10 grains per lb of powder), copper fouling seems non existent.
I just finished firing 50 rounds. I allowed the barrel to cool between each shot as I normally do. I don’t let my barrels Get hot especially with my 7mm RM’s. I had no blue patches cleaning with Sweets afterwards. Within 6-7 patches they came out white. Dried the bore and found no copper upon inspection with my bore scope. Mr Tubb looks to be dead on with his claims about how well it works. Groups stayed consistent start to finish. I didn’t chrono them but he says there’s no change in burn rate when using it.
I’m going to try it in some of my other rifles of various calibers to see if it gives the same results.
