Has anyone else had this happen shooting the 65 gr berger at 3600 fps in my 6mm rem is this to fast for this bullet . Just went to the range and had 6 out of 20 PUFF and blow up . Bad batch or to fast any comments would be great thanks Jason
Sounds to me like your over spinning them. A 1:12 is ideal for that light of a bullet. Berger recommends a 1:13. A more open twist would give you higher velocities and the bullet would stay together. IMHO
