I've seen two antelope bucks killed at 500 plus yards (518 and 537 yards, according to the rangefinder). The .243 Win., with its 1:10” twist, can stabilize the 100 and 105-grain bullets, which the hunting public wanted for deer and other big game. For the largest, toughest species within the .243 Winchester’s capabilities, the Norma Oryx is an excellent choice. BC .355. I don't think you can do better than that one in a 1:10 for deer/'lopes. These results indicate that bullets weighing less than 90 grains are not very useful for hunting deer with the .243 Winchester. lbs., BC .403, Finally, I evaluated some 80 to 87 grain bullet loads and found that they either did not generate a minimum HITS score of 500 at 100 yards, or got EKRs of less than 150 yards. This load does not have the long range, dependable killing power on deer and similar game that its flat trajectory and MPBR might suggest. Again I figure it'd kill a yote plenty dead. A quick opening big game bullet (not a varmint bullet) with a good ballistic coefficient is an appropriate choice. Hornady touts it as a great long range bullet for the .243. Hornady 95-grain SSTSuper Shock Tip (SST) bullets are purpose-built for big-game hunting, and the 95-grain, .24-caliber variant is no different. Dropping to even lighter bullets, the Nosler 90 grain E-Tip load gets an EKR of only 175 yards, far short of its 300 yard MPBR. 4.) Never shot a yote but I have shot several deer with a 243. The handloader can easy fuel his or her .243; there’s really no big secret to dealing with the .308-based case. (20 inch bbl.

Berger 95-grain Classic HunterContaining a hybrid nose design and long, Berger VLD-style boattail, the match-grade 95-grain Classic Hunter has the best BC of any .24-caliber bullet that’ll work within SAAMI parameters for overall length (and thus fit into standard rifle magazines). 80 gr when I decide to raise holyned with the prairie dogs. It’s also extremely accurate; in fact, seldom have I had any .24-cal. Go ahead with the monometals to give you a load you can use at home too. Now, it wasn’t a Boone & Crockett record book deer—having injured his right side resulting in a tall seven-point rack—but for this particular area of Texas he was certainly a shooter. More and more hunters and target shooters are switching to the 6.5 PRC as it falls in the sweet spot of 6.5 offerings with fantastic accuracy and solid bullet velocities with high BC and longer barrel life. Recoil energy is low, about 10 ft. lbs. factory ammo. First, I used the point blank range calculator at www.shooterscalculator.com to calculate a +/- 3 inch MPBR for the load. I shot a called in coyote this last winter and with a 243 winchester and a 100 gr spitzer as I hit the coyote right behind the front shoulder at about 80 yds I ended up with a hole about the size of a dime goin in and an exit hole right behind the opposite shoulder about the size of a quarter but normally I use a 1:10 twisted rifle that shoots best the 80-85 grain bullets and prefer to use the sierra 85 gr.
