I wouldn't touch ultramax with a 49.5 foot pole.
A guy brought a box of that crap to one of the local pin shoots,
and he had at least a dozen or more messed up rounds out of
100 that didn't want to chamber. Very poor quality control.
The loading was like a 230 gr RNL in .45 ACP. The shooter's 1911PD
kept choking on the things, hardcore. I used a midway .45 ACP
case guage on the things and like every so often you would
get one that didn't even come close to fitting in the gauge! The
reject rate was alarming.
FWIW, this wasn't my only ultramax experience either- I fired
some ultramax 10mm out of a guy's S+W 610 revolver. It had to
be the weakest 10mm I had ever fired, seemed like it was loaded
to "less than .40" spec.
For lead reloads, I know M+M reloading from NH does these- he
sets up tables at the shows, etc. Might be worth calling him to
see if he is going to be at Marlboro. His QC hasn't been as
wonderful as it used to be, but we're talking like one or two out
of every few hundred rounds instead of several in every
box.
IMO if one needs to use lead, you're probably better off rolling
your own reloads... then options open up considerably; you can
use bullets like MasterBlaster, etc, which still qualify as lead but
they're coated with some kind of material to reduce fouling.
