I have a few old Lyman/Ideal molds I got from my dad. For the .45 ACP, I have 452460 200gr SWC and 452374 225/230gr round nose molds. I also have a 454309 wadcutter mold, but that's more for the revolver than the 1911, so I'm not really asking about that (but over 5.4gr of Unique it shoots POA out of my Blackhawk).
Anyway, I've done a lot of reading, and lots of people are, and have been for a long time, saying their favorite loads with these boolits and Unique is 6.0gr. Some like even more. But most of the discussions I found were from 2008 to maybe 2013. Nothing much newer.
Alliant says max load for a 200gr Speer LSWC is 5.4gr. Well, the Speer LSWC has a longer nose and a shorter base, so the 452460 sits even deeper in the case when loaded. That means more pressure, and the 6.0gr load is already 10% over the max recommended for the Speer boolit.
Alliant says max load for the 230gr boolit is 5.8gr. Again, lower than what lots of people are shooting.
So, what say ya'll who like these combinations? Has Alliant merely cut back their recommendations due to lawyers?
Thanks in advance.
