I would go ahead and try the 200 grain. I don't think it's a waste of time at all. You should be able to get very respectable velocities and there will be no significant difference in trajectory between the 200 grain and a 180 grain. The 200 grain in 30 caliber is good in that it has a very high ballistic coefficient. That will help it to buck the wind better than a lighter bullet.
You live near me!! I tell you what. I will give you 5 of my 200 grn bullets if you want just to play with them. load them up and try. It would be very intresting to see what they do.I live near the race track.Kris
