Had a problem threading a Lyman 38/357 M die into a brand new Lee 4 hole turret. I have the M dies in all my handgun set ups but this is the first this happened. The die would only screw in about half way then came to a dead stop. I didn't want to force it and ruin the Turret so I tried all the other 38spc Lee dies and they worked in all the holes. Then I tried RCBS dies and they worked fine. I new it wasn't the die because I had it in another turret set up for 357mag. After close inspection of the Turret there looked to be a thread sticking out past the rest about half way in the turret and this was in all the holes not just one. I took a utility knife and kinda shaved that high thread just a hair then run a wire pipe brush on a drill back and forth a few times then and wiped it clean. That did the job and it threaded right in. I only did one hole because the Lee dies worked fine in the rest. Just wanted to share this incase someone else has this problem.
