[QUOTE="luckystryke, post: 3069263, member: 128877"] Went to range yesterday with some retumbo and Berger 156. Adg brass virgin, fed primer. These were results. I was just checking pressure and speeds, 59-59.3 just starting to get slight ejector marks and ever so slightly flattening of primers. I might push a little further but these speeds are lackluster to say the least. The Hornady is white box match advertised at 2910 mv. New fierce rival carbon. Has about 30 rounds down the tube. 24 inch barrel. I'm at 600 ft elevation I'm gonna try h1000, n565 and n570 next. Was hoping for retumbo to work as I have 8 lbs of it. Any experiences? I've read about barrel speed up but from what I gather that's essentially carbon ring causing pressure. [ATTACH type="full" alt="20240325-092313.jpg"]557483[/ATTACH] [/QUOTE]
