I really like WSF in 9mm, favorite powder for 124s around 1030-1050ish. (Universal is a close second)
Works well at heavier charges also. Good stuff IMO.
Of course it slows down the reloading process using the LNL but I like to do a quick clean, deprime/resize and expand then do a full clean on the cases.
(cases from my outdoor range tend to have sand / grit etc in them)
I then prime off press. I can watch football or whatever and prime cases- Lee hand primer. (wearing safety glasses of course)
That saves having to deal with filling primer tubes and any on press priming issues when loading. I am not saying my way is the best way, just that it works for me.
I think eliminating the resizing results is a little less flex.
This will give you more consistent OALs and the cost of reloading speed if they are off enough to cause you concern,
otherwise at start charge your probably safe with .02 short of 1.10.
In my testing with weighed charges of one powder .02 shorter made about 35 fps difference. (but of course that only applies to my test load in my gun etc.)
I am sure 1.075 would work but in my guns there was no need to go that short so I didn't.
Shot some Xtreme plated 115s with 5.2gr WSF over the weekend (Thanks Potatohead for the bullets
) and they shot well.
My sequence for the LNL
First pass
Station
1 - Resize deprime using my Lee die. (It seems to size tighter than the Hornady one I have)
3 - Flare Lee at the moment may be Lyman in the future. (don't care for the Hornady PTX that much, I have heard the RCBS PTX works better but don't know)
Second Pass (feeding primed cases by hand, no case feeder)
Station
1 - powder drop
2 - powder check
3 - bullet feed die
4 - crimp
5 - Lee FCD used lightly (I like it, some hate it, and yes I can and do load without them)
I have some XTPS left so I can load and chrono 5.2gr WSF XTP 115 @ 1.10 if you would like. (don't recall if you have a chrono)
Sounds like 1.10 is what works for you with XTPs as well.
Hope you enjoy them and the press.
Side notes:
I ended up buying a powder check die, wish I would have bought it to start with.
Hornady bullet feed die and the tubes work well for me in 9mm with RMR bullets and are worth the money IMO
