Ok I have my dillon 550 got it mounted the weekend. I have read both the manuals I have Speer 14 and lyman 49th. I am wanting to load 9mm 124 FMJ gr over unique. The lyman has no listing for 124 anything. It has 125 jacketed HP 115 HP, then jumps to 147 TMJ. The speer manual shows 9mm TMJ RN (I assume total metal jacket round nose, there the jacket covers all the lead) A FMJ covers all but the bottom correct? My real question being instead of using a TMJ RN can I safely replace the TMJ with a FMJ RN and still use the same specs? Also what does UCSP stand for?

This is just me. But I would use the Load Data from the Lyman for the 125 gr jacketed and load them to 1.130 OAL. Start with the starting load. See how well (or poorly) it cycles the slide. Use that as your gauge. Load up from that in .2 grs jumps but not exceed the middle range give or take a little. Load 10 of each. Mark them so you can look at primers. I prefer to find the point of where the slide feels slow and compare that to the listed starting load. If the slide cycles normally it's not a starting load.

Here's 124gr JHP data...
http://www.alliantpowder.com/reloade...23&bulletid=26

Searched the load database on handloads.com and while there's no 124gr FMJ loads for Unique, there is 125gr FMJ w/ unique.. I'd say that's a good place to start...

125gr FMJ
Powder: Unique
Primer: WSP
OAL: 1.15"
Start: 5.6gr -- 1170fps
Max: 6.2gr
Pressure: 31,300
Source: Alliant

Unique load data is all over the place. WOOZERS. Lyman has JHP as 4.5gr starting @ 1.075 OAL

You need to buy this: http://www.midwayusa.com/viewProduct...tNumber=185458 Also I found this really handy but you have to join.

Using Unique with CCI 500 SP primers in various cases and Win, Rem, Speer, and Hornady 124 FMJ's I'd start at 4.8 and work up and not go above 5.4 grains. 5.0 grains shows approximately 1050 fps in my G19. A load from 5.0-5.2 grains shoots well for me using 124FMJ's. I seat them from 1.150-1.160" depending on the bullet nose profile. Some such as Winchester have a sharper pointed nose and I seat them to 1.160" while others with a more rounded point get seated to 1.150". A shorter overall length will raise pressure.

You are rarely going to find data using the exact components. So you have to learn to extrapolate data. As you have already learned, not all bullets are the same. So the safe bet is to use average starting, or a bit higher, for bullets that are the most like what you are loading. Load in 0.1gr increments & shoot them in order, noting reliabilty, accuracy & any pressure signs (low or high). Load no more than 10rds (I hate pulling bullets), approach any max data w/ caution. Load to the longest OAL that YOUR gun will function w/. Use your bbl & a dummy round to determine proper OAL.
