My worst failures with commercial cast were attempts at using 405 commercial cast in .45-70 Trapdoor. Yikes!
Hopeless. The Lee 405 HB was the solution, instant accuracy with 12 gr Unique and lead versions of that HB.
Lots of commercial went down range in very hot loads in .38 Super. 145-158 gr SWCs, but more pointed, more
TC with a shoulder, really to feed in a 1911 for IPSC. 1220 fps avg with a 150 gr is pretty hot and made major
caliber in IPSC. About 70K of those went downrange over 6-7 yrs. Actually, those were .358 diam, since the Wilson Accucomp
bbl was marked "Super .38" and slugged .357 rather than the nominal .355 of normal .38 Super bbls. I asked
Bill Wilson about this name game, and he said since a whole lot more .38 cal bullets were available than 9mm,
and esp in heavier wts, he had a .38 Super chamber, but set up to a .357 groove diam and throating, hence the name change.
All my 9mm now, and even when I started, is with my own cast. Never even tried commercial cast in 9mm.
Some .38 Spl commercial cast are used, mostly when letting friends who are not good shots shoot a .38 Spl
to try it out at 10 or 12 yds. Not really worth the time spent to give them quality when they will shoot 4-6" at 10 yds with
anything.
I find a place for them, but they aren't the bargain that they used to be, I have more time available and most of my
shooting today is more for accuracy than speed. DVC - dilgentia, vis, celeritas - accuracy, power and speed - are the
IPSC motto. Much less speed today, and somewhat more accuracy. Similar power.
Mostly home cast these days, even in the H&G 68, and 452460s for good accurate .45 ACP loads.
