I'm a new member here and would like to take advantage of the combined knowledge of the members. I have a Stevens 200 .243 action and was thinking of doing a wildcat in .243 Middlested or .224 TTH. I will be using the gun at ranges beyond 300 yards and will be using it on game(antelope and small deer) along with punching holes in paper. I plan on using bullets ranging from 60 to 90 grain. My question is what cartridge will be easier on barrels and just what is the life expectancy of a barrel in the two calibers? What about throat erosion? What velocities and trajectories can be expected? Which round is more reload friendly? Please give your input.
Thanks
