[QUOTE="benchracer, post: 905449, member: 22069"] The 22-250AI is a better choice according to this: [url=http://www.accurateshooter.com/cartridge-guides/22-250/]22-250 Cartridge Guide within AccurateShooter.com[/url] Re-chambering a .223 will not work because of the difference in case head size between the two cartridges. I don't see how there would be much difference in barrel heat or barrel life between a 22x47 Lapua and a 22-250 AI since there is very little difference in case capacity. Hodgdon shows 3500 fps from a 70 grain bullet with Superformance in the standard 22-250. That is +550 fps over a comparable factory load in .223. There is no way you are going to get that level of performance without paying a price in heat and barrel life. I can tell you from shooting my standard 22-250 that if heat and barrel life are your concerns, you should stick with a .223. A fast twist barrel with good bullets will take you a lot further than you might think. A .223 is also quite a bit less expensive to shoot. The gap gets bigger when you consider barrel life. I personally prefer 22-250, but I am willing to accept the trade-offs. [/QUOTE]
