Tubbs compound #1 and #2 are real course, for one thing, I had the .338 kit, decided I didn't want to use it, even though the reviews for it are excellent, I sent the kit back to Cabelas. I just flitzed the .338-06 barrel instead, when I took the barrel back to the smith to cut the neck a little deeper for the Weatherby brass, he was amazed at how good the bore looked with a borescope after the flitz treatment. It's all I'll ever use if it's good enough for him!! :wink: Tubbs cost the better part of $30, so for the difference in cost, the Flitz/JB or whatever you choose is much more economical and works!!
