RE: 243 bullet size
I played with a TON of 243 bullets over the years, and I settled on the 95gr Combined Technology BT. I've only had one deer out of probably a good 50+ that has taken a step with that lil pill.
2feathers - I did some experimenting with the 95gr SST and wasn't impressed with it at all. Never had an exit, and it retained no weight what-so-ever. It acted alot like a varmint BT. Out of the half dozen deer or so me and my buddies took with that load, all requireda follow up shot or 2 to put 'em down.
