I tried some more combinations with the Berry's 180 Gr. Plated bullets.
(15 Rounds Each)
WW brass
WSP Primers
5.8 Gr AA#5 (Good Accuracy)
6.0 Gr AA#5 (Very Good Accuracy)
6.2 Gr AA#5 (Accuracy not very good - one bullet keyholed)
5.4 Gr Unique (Accuracy not very good)
7.0 Gr HS-6 (Shows some promise)
7.3 Gr Blue Dot (Shows some promise)
7.7 Gr AA#7 (Accuracy not very good)
Functioning was 100% on all loads. No visible signs of excessive pressure.
