Hoping someone can help me out. Am seeking load data from Hornady's manual for their 124 grain XTP in 9mm. Will be using Universal or Longshot as that is what I have on hand. Lyman & Hodgdon use different bullets for their data. Curious as to what Hornady recommends. I have ordered Hornady's manual but looks like it may be a few weeks before I receive it. Thanks in advance
 
Not what you have.

7.8g of AA#7 with 124 amazing accuracy, meters like water. Play with seating depth, varying .005 at a time, you will NOT believe how much the seating depth affects accuracy, especially in small amounts. 1.270" oal with 124 Speer Gold dots, +P load, have no idea on the XTP's.

Thanks for the response. Main concern is COAL. Hodgdon & Lyman are real close on the charges. But Coal is a bit different. Lyman is 1.075 & Hodgdon is 1.150, not exact same bullets though. Wondering what Hornady recommends. Want to err on the side of caution. Thanks
Good tip on seating depth vs. accuracy. Will experiment a bit once I get a baseline & my range opens back up!!! This Covid 19 sucks!!!
 
Yes I have. You have to pay for the data. Either buy the manual,(already on order) or download the app and pay that way. Tried the app its a PITA
 
Load a few batches of 10 or so. Look at various COLs, compare them to factory specs, do a ‘plunk test’ with the barrel.

Then do some shooting, chronograph if you have access. Once you verify reliable cycling, reasonable chrono speeds, you should be good.

A while back I was doing load evaluation with Speer bullets, Win-231 for my 380’s. I loaded them just below factory speeds, within Book charge weights, called it good with reliably cycling.

Just don’t load 200+ rounds until you check them 1st.
