243, 257 Roberts, 25-06, 6.5X55, 260 or 6.5 CM.
If you think about it, a 223 with a 1-8 or 1-7 twist is also very good for accuracy and very inexpensive to fire. Shoots 55-80 grain bullets very well.
At 200 and under, the 223 works fine on deer with correct bullets and doesn't kick. Loaded with nosler Partitions, Bonded bullets of 60-70 grains or expanding solids like the GMX or the Barnes it is a very good deer killer
I have seen it done a lot more then I have done it myself, but I can say what I have seen has impressed me for more then I thought it would when the 223 was made legal for deer and antelope here in Wyoming.
So far it's been 100%
But....you didn't tell us what the rifle would be used for, so I and everyone else afrre really just making guesses.
Another option for the .223 is the Speer 70 grain Semi Spitzer. That's all we used in my old 788 Remington with a 1:12 twist rate. It stablized them fine and killed very nicely out to at least .200 yards. That's extreme range for 90% of the shots at deer that I've seen.
