I had to grind away the openings on the Lee priming tool itself (where it holds the auto prime shell holder) so it would accept the 300 WSM case; the shell holder would fit the tool and accept the case, but the tool was not wide enough itself to accept the case.
The little powder funnel that cane with the kit spilled powder all over when attempting to use it with the 300 WSM shell, I ended up making a paper funnel to "funnel" the powder from the plastic funnel.
The little chamfer bit that is supposed to clean up the inside and tyhe outside of the shell after trimming and sizing works OK on the inside of the shell, but doesn't have the depth to reach the outside shell edges (due to the way that the 300 WSM shell is designed).
Every other component works satisfactorily; certainly a little yankee intervention and American ingenuity made the kit work.
Kindest regards,

For rifle I wiegh each charge. So I put the powder in my scale pan first. Then use the funnel to put in the brass. Are you trying to just stick the shell up in it?
