34.0 grains of re 16 filled to neck shoulder junction. Comparable grouping to re 15, but not much room left if jamming 105vld. Going to see how h4350 works, may run into same situation. Thanks for replySpeaking from 6Dasher experience, 34 to 35.5 has been pretty much my working range.
RL16 is bulky, drop funnels and slow pours are needed - IME
Good Luck
