Anybody use this stuff ? What do you think?

Feeds great.  I have a problem 3" 1911 and the PB ammo fixed the problem.  It is all +P (at least the .45 ACP stuff I used is +P).  Not a big deal if you weapon is rated for it.  Mine isn't, and I ended up breaking a part shooting it.  Not sure if it was a coincidence, but I'm going back to non +P in that particular pistol.  

I thought I saw a change in POI, maybe a bit high, but I was shooting on a very cold day after an arm workout in the gym, so all bets on my skills are off.  

Quoted: If your 3" 1911 won't feed reliably with many common JHP .45 designs, the standard velocity Remington 185gr. JHP load feeds as well as ball in every gun I ever shot it in...if they still make it, that is.

If you're referring to Gold Sabers, that is exactly what I am switching to.  Just bought some, but it's been too cold here to go try them.

I use the 100 gr PB in my Kahr PM9. My PM doesn't like anything except FMJ and PB, but it has never choked with those. With other JHPs that I've tried I get intermittent jams every 40 rounds or so. BSW

I've used quite a bit of PB and it works great in both my 1911's.  A full size and Kimber ultra elite.  I have never had a problem feeding/ extracting.  I can't say if it's the best in the terminal field but for reliability it's great.
