Ok so i have a old ruger m77 sittin in the gun safe for like 2 years un touched, maybe longer. I used it as my "loaner" gun if the situation arrived. Well i was doin a little ballistic research and decided to look into the old 243 outta bordom. @200yards your 243 should hit around 1.5-2" high @100, and about 6.5-7" low at 300yards. This took me aback because i always thought of the 243 as a 100-150MAX yard rifle. I took the big bores for my 200+ shots. With 1225 ft. lb. energy at 300yards its more than enought to take down a deer. I tested myne with 95gr ammo and turns out myne is +1" at 100yards and dead at 200yards, 250yards sets me about -3". I was impressed with my little loaner and am more comfortable useing it to greater ranges now that i have a little more knowledge on it.
