Last year I bought a NOE 360477 mold to use for a accurate 50 yd load. After sizing to .358 dia in a Lyman 450 and loading in 38 spcl brass with Bullseye and Unique I had a problem with poor accuracy and leading in the cylinder and thats how I left it till now.
Looking at the boolits I cast last year I discovered that the portion above the crimp wasn't sized, still checking .360 dia.
I pulled the Lyman sizing die and found that if the boolit was entered to the top lube holes the taper in the die extended deep enough that the top portion wasn't sized.
I plugged the top holes and pushed the boolit to the 2nd set of lube holes and resized all that I cast last year.
Hopefully accuracy will improve and the leading in the cylinder will disappear.
Has anyone experienced similar problems?
Is it common to have to push the boolit that far into the sizing die?
