Since 8/3, I've put 400 rounds of Geco 124gr FMJ through my P99 9mm with no problems, no jams, no FTF. One comment though, the Geco stuff is real cheap, but real dirty!
The Geco brass cases seem to "flake" a bit also, leaving specs of the flakes/dust.
Last week, I started on a box of Winchester white box (100) 115gr FMJ. After about 50 rnds, the P99 is remarkably clean, as compared to after firing 50 rnds of Geco.
I have yet to try the box of Hydrashok 124gr JHP.

With daylight hrs. growing shorter, my range visits will have to move to outdoors weekends only soon, or weeknights indoors. The trouble with our indoor range is that it's Lead Only Ammo. Don't know how the P99 would handle RNL (I can get remanufactured 9mm RNL, local in MA).

Has anyone tried RNL ammo in the P99?
What has been your cleanest range ammo?
-thanks

Don't know about RNL.....but I have been shooting the Geco 124 in my P99 for a few months now. Yeah....it is a little bit dirtier and smokier than the Winchester 115 white box, but its a heck of alot more accurate. At least in my gun it is. Ill take accuracy over cleanliness any day.

Where are you guys finding Geco? I haven't found any for a while. The last batch I bought from Bob Lippman, but he has ceased selling ammo.

Natchez hasn't had any for a while.

Appreciate any leads as this is the best 9mm ammo there is IMHO.

We banned Geko ammo from our range when we found some of it had a steel core (check with a magnet). It was damaging our backstop. I shoot a reload with a 147gr. Lazer-Cast lead bullet with 3.6grs. of Universal powder or 4.2grs. of Alliant Power Pistol. It is a great action pistol load that functions fine in my P-99 9mm. Both loads use a Federal 100 primer. The heavier bullet mimicks the military subsonic load which is very accurate. Shooting lead is no problem for your P-99 although you may have to compensate re:pOA/POI with different bullet wgts. FYI- when shooting commercial reloaded ammo it would be wise to use a cartridge gauge to check each round. You may find that some are not up to spec. Commercial reloaders go for economy not acccuracy hence the use of "dirty" powders and mediocre bullet lube. Quality in, Quality out....
