Here's my problem I got a new mold I'm trying out for my 9mm. I have been using a Lee, 124 grn round nose bullet. My new mold is a Lee, 124 grn tc bullet. My question is I can't find a listing for the new bullet in any reloading manual and I am concerned about the oal. The RN bullet lists the oal as 1.125 the new bullet is a couple thousands shorter (.605 as opposed to.585 +-) do I adjust my oal accordingly or keep it at 1.125.
Be kind to the newness. Any help would be greatly appreciated
Thanks
