231 would be my vote.
Tightgroup would be just fine though
I have been happy with 231. I chronographed a 10 round string of 4.7 grains of 231 under a 115 grain Berry’s bullet out of my wife’s Beretta 92.
They were very accurate with an average velocity of 1078 fps, 18 fps standard deviation and 43 fps for a maximum deviation.
A bit lighter than most factory loads but cycled the Beretta and four other 9mm guns reliably.
• W231 (also sold as Hodgdon HP-38) was for decades the best selling powder. Generally speaking, it can be used in almost any handgun cartridge. It is a moderate burn rate, meters very accurately with excellent case fill in auto pistol cartridges and good case fill in revolvers. The wide load range and moderate speed (read as "very forgiving") make it an excellent powder for beginners. The load range in 9mm is about 1.2gr. You will not typically find published load data for W231 and 147gr in 9mm due to the very restricted load range, but for 115, 124 and 135gr it's excellent.

That's impressively fast, with W-231 at only 3.8gr and 147gr.For blammo ammo, I use 3.8 grains of W231/HP38 under a 147 grain RMR FMJ at 1.14" overall length. Provides 980-990 fps in my 5" Canik barrel and provides very consistent velocities. It's also still subsonic in my 10.5" AR. ZERO issues with this powder under a 147 grain bullet.

Are you sure they're going that fast?
From all my years loading 147 grain bullets out of 9mm pistols, 1000fps. Is almost always the benchmark a full house load, and typically achieved with a tad slower powder like Power Pistol, BE86, Blue Dot, Longshot, etc....to get the velocity up and keep the pressures in the limits.
If I had a 147grain WIN- 231 load in 9mm that was pushing 1000 fps. I would reconsider my powder choice in the interest of keeping pressures (which are completely unknown to us) lower if possible.
HP-38 and Win 231 are the same. They both work well for 9mm and many recommend them as the powder to start with. Today, it seems like W-244 is going to replace the HP-38 in that it is cleaner (CFE agent) and about the same burn rates and power curve.I don’t have any experience with Titegroup, but I started my reloading adventures with 231 and have come back to it for 9mm and 38 special. Meters well, shoots well.
This thread is like a data journal for loading practice/plinking plated 9mm .... it is outstanding. Worth taking notes and entering data into my notebook for cross referencing.
I'm so done with Unique in my plinking 9mm ammo.
