20 Ack Hornet
Using AR2205/H4227 I am getting the following velocity results with 32gn BKs and Rem 7.5s.
11.5gn ... 3100fps
11.8gn ... 3190fps
12.3gn ... 3250fps
For reference Kindler got 3101fps at 12.5gn H4227.
At 12gn I am compressing the load so I plan to give 2400 or N110 a try.
Kindler went up to 14gn in a 1.4" max length case. Note I have a 1.36" max length case to fit magazine.
Does anyone have some results they can share.
