Loading Alliant Unique powder with 124gn HP Berry's plated. Can someone confirm 3.5 - 3.8 gr? More importantly what is the OAL for this load? I've looked around and can't seem to find anything. I am running out of time to load this before I go away. Thanks in advance.

I've been using 3.8 to 4.2 of W-231 and a c.o.a.l. of 1.170 under a 124 berrys plated round nose in my XD9 with good success.
The 75B has a pretty short chamber compared to many other 9mm guns, and adjusting OAL according to load data doesn't work for many bullet profiles. I suggest taking your barrel out and using it as a sizing gauge. Seat your bullets just short enough that when you insert a cartridge in the chamber and press on it, it still falls freely back out when you tip the barrel upwards. You want your OAL to be as long as possible, so start at the point where they get stuck or don't go in all the way and gradually seat the bullet in further until they finally drop free.
Then compare this OAL to that stated in the load data. Depending on the bullet profile, it might be significantly shorter than its supposed to be. If it turns out to be much shorter (like 1.095 instead of 1.145) you might consider starting off with a load a couple 10ths of a grain lighter than the advertized starting load, and work up from there.
