Please let us know how the hybrids shoot. What MV are you getting?
Just got back from the range after shooting some test loads w/180gr Berger Hybrids
Load was 71.5gr Retumbo, Fed210M primer, bullets seated to within .005 of lands. All 4 5-shot 100yd groups were sub 1/2 moa. Average velocity was 3130fps out of 29" bbl with SD of 9fps. Tried 72.0 gr of Retumbo but SD started to expand without a significant gain in velocity. The only evidence of pressure was somewhat flattened primers but no cratering or bolt swipe and bolt lift was normal. The 71.5 gr load appears to be worthy of further testing......not sure that I can improve on what happened today though. I am really getting to like this caliber.
