On Paper the .243 should be able to reach out to 400 yards for Whitetail w/ 100gr., the problem is outside forces on the bullet. Because of its' light weight, it is more inclined to impact different then its' POA w/ wind, high or low humidity.... There are lots of folks that use it w/ great success, but it is not a round that some feel comfortable with. I use a 6.5 and for years was told it was to small. It was funny when the .260 came out and guys thought it was the greatest thing since sliced bread. These were the same guys that told me my 6.5, with the same bullet that had a faster velosity was not enough. Shoot what you feel comfortable with.
This discusion is one that has played out many times here in my area. As a teenager (1973) the top weapons used for deer (mule,whitetail 120 to 210 lbs), Elk ( 900-1,000 lbs), Bear ( heaveyest average 350lbs). Were the 270 30-06 and the 243 yes there was other cal.'s but this covers the most. I have seen on more than a few hunts a 150 ish deer brought down at the 400 yd mark with a 243 90 gr hot core speer. It wasnt till the ammo people needed to up sale's And all the gun mags. started publishing new calibers. Telling every one that it is crazy to hunt wild game without the new cal. 8mm rem mag. (as example) I am sure you older guy's remember these time's in the gun world. WOW there were so many cal's brought out. everyone had to have the newest and the best. Today I go hunting coes whitetail in my backyard (white mnts in az next to new mexico) they average 80lbs, A trophy starts in the 130 area. Being hunted in bushy areas were a 400yd shot is hard to come by. with cal's warbird' from lazzorony 338 win, 300 win just to name a few. Now I shoot a 6x284 with a 100gr. for every thing. Most of the local's who have hunted most of their lives here use a 22-250 for the small deer. So lets just say the 243 is more than enough for deer. As long as you are not educated through guns and ammo mag. Which I remember one artical that stated a 308 win. was not good for anything other than a varmit round on thin skin game at 250 yds. And so far what I have read is arguments against the 243 from the the book learned with out practical application. MY 2 cents
