Would you mind sharing your loaded info? Powder and weight , Brass , primers, and most importantly to me seating depth. I've heard that they like a .050" jump and that's where I've started. Not much success with that jump, compared to my 140gr Berger Hybrids. Trying the same load with the RDF's as the Hybrids, that shoot well to me.(3/4"-1" 5&10 shoot groups at 200yds) My recipe for The Bergers that I'm trying with the RDF's is Lapua SR brass, CCI-450,43.5grs of H-4350, seated at 2.820"-.825" OAL (=.040" jump). And the Bergers are 2.840"-.845" OAL which is about .065" jump. Bergers AV 2775fps with E/S 16 and S/D 6. The RDF's with the same charge went 2792fps AV, E/S 15, S/D 5, but with 1 1/2" - 2 1/4" groups at 200yds.
