I used to NEVER shoot that stuff. Then recently, in the interest of economic sensibility, I bought a few boxes. . .
Like others have mentioned already, very dirty.
What made me get rid of it all for free was THREE SQUIBS IN THREE RANGE SESSIONS.
A vast majority of what I shoot through all my firearms is my own personal handloads. Prior to this I've never had one squib in over 30 years of shooting. I won't tolerate abysmal performance and potentially dangerous / life threatening situations to save a few pennies.
Made it real easy to justify the Dillon 650XL sitting on my bench now
