Humor me.

For the most part Jack is right, overbore cartridges are just barrel burners, but with todays ever evolving powders and bullets you can to an extent prolong throat erosion by being selective with your powder. Usually in an overbore cartridge like the .243 they will be loaded with slower than youd think powders anyway, but it is possible, and I have seen it done to use an even slower powder to get a cooler burn, but the trade off is lack of efficiency and velocity loss. The best way to minimize throat eronsion IMO, is to shoot the heaviest bullets that your barrel will stabilize and use the slowest powder listed that gives a complete burn.
