I have been trying to get some real accuracy out of a CZ 527 in 300 black out. I sent one back to them with targets I had shot and they sent me a new rifle. I have not shot the new one enough to tell how well it will shoot. So far I have only shot one load at 100 yards with a NOE clone of the :Lyman 311331. Groups have been around 2 inches,, not great by any means but a place to start. I am looking for some data using faster powders like my all time favorite Unique. I am more interested in cast bullets of 165 gr, and heavier. Like all cast bullet shooter I have many moulds so can use data for just about any bullet would be helpful. If need be I can always borrow whatever I dont have from Ric in Yakima. between the two of us we pretty much can come pretty close to finding whatever is needed. I am mostly interested in info on faster powders but would appreciate any data that you have had good results with.
if you need me I will be at the range
