People I know won’t shoot L&B ammo.
Too many hangfires and stovepipes.
I have had almost no problem with S&B FMJ for practice.
I say almost, because when I do have a very rare malfunction, it is time I clean the gun.
All my 1911s have fluted ejection ports. So few to no stovepipes. If I get one, I have probably just put a few hundred rounds or so through the gun without a cleaning.
I always do a thorough cleaning before putting the gun into real service with Federal HST.
S&B is okay. Besides, you get a chance clearing malfunctions.
