Reloaded a bunch of berger 243 105 gr in various powder loads form minimum to max... Every single bullet tumbled to the target .. I ll say rifle twist will always stabilize a bullet, may shoot eradic but not tumble... I mean if I wanted to relive Vietnam than tumbling bullets are it.. Than I loaded 80 psp and shot .25 moa, should I even try lower weight vlds .. Twist is 1-9, also I believe its wasting my time and money shooting anything heavier than 90 gr.. Just not enough powder powder to push a heavy bullet in 243.. Any recent experience ??
