Seafire,
Wind-drift is NOT dependent on bullet weight. Instead it's totally dependent on two factors, given the same atmospheric conditions: ballistic coefficient and muzzle velocity.
The 30-grain V-Max has just about exactly the same BC as the 40-grain CCI HP. But the 30 V-max starts out faster, so shoots flatter and drifts less in the wind at any range. I know this not just from theory but from shooting a bunch of different .22 Magnum loads in the field.
Thanks for a clarification to the campfire... I;ll admit to shooting the 30 V Max in the Marlin 22 Mags I have, but not really any more than at the range or at a gopher or two in the yard.. since I live right off of what use to be a golf course...but I've never tested it out for distances out to 200 yds or more...
I know its more accurate that my old tried and true 40 grain CCI HPs and FMJs...
and after Obummer got into office, I tended to load the old 223 bolt action down to those sort of velocities with 40 grain bulk plastic tip bullets and 50 grain TNTs....
