Alloy for the Saeco 315 and Lee 170 gr were COWW. I tried some Lee air cooled at about a 13 BHN hardness. I tried some Lee and all Saeco water dropped, which runs up around 23-25 BHN hardness. I also had some 175 gr bullets from GT bullets. They use a 96-2-2 alloy.
All three were always gas checked. I tried both .310" and .311" sizing.
Lube on the 175 gr GT bullets is some kind of softer commercial lube. On my own Saeco and Lee, I tried both Carnauba Red and TAC 1.
