I’m looking for a single powder that will work in a couple of Rugers, a mini 30 and a mini .300. I want a light load that uses 150 to 170gr cast bullets. I have an old Ideal mould # 311413 that makes a nice 170 gr pointed GC .309/.310 bullet which work ok in my mini 30 propelled by 27.5 gr of H335. I’ve not worked up an accurate load yet, just trying to get the rifle to run. My other mini[14] is at Accuracy Systems currently getting the .300 bbl installed. Thanks ahead.
