I typically shoot handloaded 124s with a moderate amount of unique powder behind them! I seem to remember that a longer bullet seems to work better, or at least one that is seated out longer with a larger OAL. Some people like Winchester 115 gr FMJ, some people say it doesnt feed well. If I am shooting a 9 for ultimate accuracy without finding a load a particular gun likes, I shot Winchester 115gr Silvertips. I dont like the PMC ammo as it is dirty. I shoot 115gr Remington's UMC ammo quite a bit. S&B and Fiochhi seem to make a good load in 9mm. The S&B is a little hotter than most loadings, which may be a little better for some guns that might stovetop jam (usually the brass is not being ejected because of a weak load). From reading the individual posts some guns like one load over another. When testing a particular ammo that you are planning on shooting in a Luger, I like to do a power check. I will load one round and fire the gun! Then I check to see if the hold open engaged, then do it again. If it engages 5 times in a row, the ammo has adequate power to work the action. If not, I could probably go to something a little hotter. 30 Lugers seem especially needing a hotter load because that light bullet has to be going faster to have enough umphft to work the action and compress that tough main spring. Any way, back to your original question, I think it is any fmj 115-124 gr bullet in a standard loading that will operate the action AND feed well. That might mean experimenting some, but I think a good place to start is 115 gr Winchester FMJ or UMC ammo. I DONT like CCI BLAZER ammo as it tends to stick in the chamber. The local gunsmith says they dont guarantee ANY gun intheir shop will work with them, he has even seen instances where a brand new S&W revovler has to have a mallet tap the rod that emptys the shells to get them out. Not a good thing! Some guns will tolerate this ammo, but not all! Thor
