I have not found any great discernable difference between spitzer and round nose bullets at any range I have tried, even at 1000 yds.
find that boat tails vs flat base do show enough difference to merit some discussion, depending on velocities and distance.
I'm NOT saying I don't believe you but...
past 200 yds--that's hard to believe.
NOTE - I admit I have used ANY R N in any CF except 30-30 SO I have not tried them.
***It seems to me that IF a minor diff in the BT makes some diff>>>>>R N vs "Spritzers" outta show up.
AGAIN, I haven't tried them.
