These bullets are FANTASTIC! These turn the .338 Spectre and my own .338 6.8 based wildcat into a viable big game round. Since these bullets expand to velocities of at least 900 fps and hold together very well up to 2100 fps, this bullet transformed my flop of a cat into the as planned 300 yard deer rifle, and with the Spectre, it and the Maker 300 gr. subsonic are about the only bullets that will expand at the Spectre's velocity range. On top of that, these bullets are incredibly accurate, holding five-shot inch and a half groups at 200 yards. I simply cannot heap enough praise on these bullets.
