I ended up loading the 200 grain WFNGC from MBW on top of 12.8 grains of No. 9 with a COL of 1.250. Functioned just fine in my XDM and I had no problem loading a full magazine at 1.250 or 1.255.

Thanks 4given, Most books seem to list the lower end of COL as 1.240 but it seems to need to be less than that for the WNFP.

Going to work up a load for the Montana Bullet Works Wide Flat Nose 200 grn. bullet on top of AA No. 9 . Will be shooting it in a Springfield XD(M) 4.5" .  I have read where some have had to seat the bullet deeper in order for it to feed right or even fully load the magazine in Glocks but don't know about the Springfield.  I read where DoubleTap when to an COL of 1.242 with what looks like a similar bullet. Would appreciate hearing from anyone who has loaded this bullet.
