One of my biggest gripes with reloading manuals is they never seem to plublish the oal of the bullet they use for their data. For many years I have used Precision Delta 124 grain JHP which measure around .586. Over the years I have worked up loads using Power Pistol and CFE Pistol and found my COL at 1.100 is a length that fit all my 9mm pistols.
Recently I purchased some 124 grain Nukes from RMR and they measure apprx .542. What a difference in bullet profile from the Precision Delta. I found I have to go to a COL of 1.065 to pass the plunk test in all my 9mm.
Here are a couple questions that maybe people can help me with. Since I have to shorten my COL to 1.065 and everything else (powder/primer/case) stays the same, am I safe to assume since the math tells me I have .009 more space inside the case I should be go to go? That said I will probably drop down .3 tenths on the powder and work back up just to be safe, but I would like to see what people think about just loading base on bullet length. Also is there any reason why powder manfactures or bullet manfactures do list the bullet length in their reloading info?
