[QUOTE="Varmint Hunter, post: 7870, member: 313"] Many of you have suggested that the 243 or 243AI with the 107gr SMK bullet would be the ideal longrange PD cartridge. My suggestion of the 22-243AI with a JLK 80gr did not seem to curry much support. Here's my question: Both the .224 80gr JLK and the .243 107gr Sierra bullets have very similar BC's, aprox .510 - .520. If the 22-243 can fire a high BC bullet @ 3,600 ft/sec and the 243(AI) can fire a bullet of similar BC @ aprox 3,000 ft/sec; how can the .234(AI) be a better longrange combination? The 22-243AI should shoot significantly flatter AND resist wind much better (similar BC and shorter flight time) than the 243(AI). The 22-243AI would also produce less recoil. As far as accuracy goes, I'm assuming that both cartridges are fired in quality rifles with the same potential for accuracy. Am I missing something here? VH [/QUOTE]
