OAL 9MM 124gr XTP
« on: March 04, 2008, 09:41:34 AM »
Manuals seem to vary a lot on the loaded length. What should the length be? I am using HS6 and Unique with a 124 grain XTP. This is my first time loading 9MM, am used to loading bullets with a crimp groove.Thanks for your help.

The Hornady Handbook (6th Edition) shows the C.O.L. as 1.060" for the 124 gr. HP-XTP

Thanks ORE-E-GUN BILL, I know  HS6 isn't supposed to be compacted so I was a little afraid of getting the bullet too deep. But didn't want to have feeding problems by being too long. Thanks Again

You  need to find data for that specific bullet. 9mm has high pressure and seating a bullet just 1/10" deeper than recommended will increase the pressure to dangerous levels.

FWIW the Hornady Handbook lists HS-6 - 5.1 gr. minimum and 5.9 gr. as MAXIMUM for your 124 gr. HP-XTP

Life was simple it seems when i was only loading 44's and 38's. I am fairly new at reloading so please excuse my concerns, I do not mean to question or refute any members opinions or loading information as it is greatly appreciated. I only have Lee's reloading manual and Hodgons 2007 annual manual, so this is where this information comes from. Lee's manual lists 124grain jacketed bullet with 6.4 to 6.8 grains of HS6. Hodgdons manual lists a 125 grain jacketed bullet with 6.4 to 6.6 of HS6 and a 130 grain bullet with 6.3 to 6.6 of HS6. Even more strange ( to me )Hodgdon lists a Hornady 147 grain XTP with 5.0 grains of HS6. Based on this information I loaded 10 124 grain XTP's with 6.4 grains of HS6. Based on the information Bill  kindly provided me on the 124XTP this information that I have is way off. I have not shot any of these and don't intend to until I am sure I have a safe load. Hate to have to pull these but if they are not safe it will be done. Tried pulling one and after a lot pounding I hadn't gained much. Again thanks  for your help and indulgence.

As noted by Questor: "You  need to find data for that specific bullet."

With that, I can only add that the Hornady Handbook has generally been on the conservative end of the spectrum on load info, in my experience. But, I would rather error on the side of caution and load conservatively, (when starting to work up a load), than to end up with a damaged weapon or worse.

Be safe.

Bill

Edit: An example of different loads comparing Hornady Handbook vs. Lyman 48th Edition
115 gr. HP-XTP used in both of these loads:
Hornady Handbook - HS-6  - 5.7gr.  Starting load ----- 6.4 gr. MAXIMUM load
Lyman 48th Edition - HS-6 - 5.7gr.  Starting load  ----  7.2 gr. MAXIMUM load

The manuals and handload books are guidelines. Your results may vary...

My Lyman 43rd and 45th Editions show a max overall cartridge length for the 9x19, with bullet, to be 1.169".  Both manuals show a Unique powder charge (HS-6 not listed, used or developed back then) with a 124 gn remington fmj ranging from 4.3 gns for 891'/sec to 5.8 gns for 1149'/sec.  Test firearm was a S&W M39, 4" bbl.  HTH.  Mikey.

Thanks Everyone for your help. Pulled all bullets this mourning with suspect overloads. Will be using load provided by OR-E-Gun Bill,  which was also stated in an article by Chuck Hawks, 5.9 as max for HS6. So we can put this one to rest. Thanks Again,Ken
