Im looking at getting a marlin 336 and i have a question about the differenteffects of the microgroove and ballardrifling on bullet performance.

From what i understand the low spin/turn(not sure of the term) rate of the microgroove is ideal for flat nosed bullets. Then on the other handthe faster turn/spin rate produced by the ballard rifling is ideal for pointed bullets.

So my question is, which type of rifling has less of a negativeeffect on the performance of a less than ideal round?In other words,is it better to have a flat nosed bullet spinning too fast or a pointed bullet spinning too slow?
