I loaded some 9mm to test. Was going to chronograph them.
Now I question the col.
All rounds were made with unique powder 5.7gr - 5.65 gr.
Winchester wsp primers.
First is
115gr. FMJRN my col is 1.148" to 1.152" Lyman 47th said 1.120" col.
Next is
115gr. JHP my col 1.151" to 1.155" Lyman 47th books 1.090"
Next
124gr berry plated HP same charge my col 1.140" to 1.143" Not sure what col should be.
Other books only state Min. OAL. and Max length.
Is the COL ok or shouold I redo the seating of the bullet?
Any help appreciated.
