Im late to the party here but Ive killed a pretty nice sized pile of deer with a 243. I guess my favorite is the 95 NBT.... the 90 gr version seems to be just as tough and works as well. Thing is... Ive only really used one bullet I wasnt real happy with and that was a 100 gr Sierra BT. I have a large stash of 95 gr nbt's I bought up from SPS on sale a few years ago as well as a large stash or 100 gr SP Hornady's. Lot of things work well in a 243. Ive killed them with everything from an 80 gr ttsx to a 105 Speer.
