Check out the above link for info on the .243. My personal favorite was a 90 grain nosler ballistic tip which I can't find anymore. I'm using my 30-06 and .44 this yearbut of all the guns I own and have taken deer with, nothing has ever taken deer down faster or caused more internal damagethan my A-bolt with a 90 grain BT.(OR BEEN MORE ACCURATE).243 gets a definite thumbs up from me, its like lightning on deer.
