I like the Remington ammo, and have about 1,000 rounds total of FMJ and SP. I like that the R-P JSPs and FMJs print to the same POA. I also have a couple hundred rounds of WW 110 FMJ, which is about the same as R-P. I have also shot Magtech (Very hot) which I like a lot, Armscor, and Prvi PPU. All are good ammo.
I have used Aguila, but found I had to put the rear sight on 200 instead of 100/150 to do 100 yard shooting. Also it did not function 100%, and had occasional FTFs. I cured that by using a deteriorated recoil spring (9 7/8"). Then it did not want to feed the top 10 rounds of a 30 rounder.
I have tried Wolf and Tulammo. Both stink really badly, group size was awful, and recoil and report varied greatly. Wolf ammo chipped my extractor, so I sold the rest of it off (too bad, I had bought a case of 1,000 rounds really cheap!)
