115 gr FMJ with 4.8 gr W231/HP-38 at 1.135" OAL - My reference 9mm target load. Works reliably in multiple pistols with good accuracy and clean burning.
124/125 gr FMJ with 4.5 gr W231/HP-38 at 1.135" OAL
124 gr plated RN with 4.2 gr W231/HP-38 at 1.135" OAL
124 gr Berry's HBRN-TP with 3.8 gr Bullseye, 4.0 gr Titegroup, 4.5 gr W231/HP-38 at 1.135" OAL - Very accurate target loads
125 gr Missouri Lead RN with 4.0 gr W231/HP-38 or 4.0 gr Promo/Red Dot at 1.080"-1.100" OAL - Economical target loads that burn clean and don't lead the barrel.

► Bullets. Most 9x19 Luger guns have a twist rate that prefers 124/125gr bullet length/weights. Bullet brand and ogive shape are up to you. An anomaly to this may be the Berry Mfg 115gr hollow base, which have the length of the 124gr without the added cost.
► Powder. I get excellent accuracy around 1030-1050 fps. IMHO, you therefore want a powder who's "max load" speed falls around 1060-1070 fps, so that the powder is still burning efficiently in the 90-93% range when shot at those target speeds, but without the "max load" pressures for the gun's sake.
► Putting it all together. In my mind, a large part of "accuracy" is nothing more than repeatability. IOW, the bullet flying in the exact same manner each time on its way to the paper. That means all the physical properties need to be keep as close to the same as possible for each cartridge. That is to say: same brand of brass, same OAL, same primer, exact same weight powder, same crimp, etc.

Yes, I agree. More consistent chamber pressures will translate to more consistent muzzle velocities with lower standard deviation (SD) numbers which then will produce more accurate shot groups.
IMO, for lighter target loads, since slower burning than Unique/Universal powders tend to produce more consistent burn/accuracy at high-to-near max load data, W231/HP-38 and faster burning powders are better suited for producing lighter target loads utilizing mid-to-high range load data.

115 grain LRN
4.5 grains Unique
Cheap and easy.

In my relatively new and limited experience with reloading, I have found that 147gr. FMJ Xtreme bullets seem to work better for my gun. ( Walther P-99) But now after reading rfwobbly's post, I am questioning that. I will be watching this thread closely to see what others like. I was going to buy a bunch of cast TC 150gr. for practice and IDPA, and try them. I may look into another direction.
Thanx for making this post!

124/125gr LRN bullet over 3.9gr to 4.4gr W231/HP-38 makes a great range load.

115 fmj over 4.9 grains of universal clays.

Whatever's cheap!! Usually some Win231 and some form of a 124gr bullet, plated or Precision delta FMJ.

A 173gr SWC in a 9mm, I don't think so!
