The only 22 ammo I will never buy again is the W-W X-Pert, a plain lead HP bullet with a flat nose, wouldn't feed in ANY 22 I ever tried it in, semiauto, bolt, you name it. I found the Federal and Remington bulk ammo works fine in nearly anything, but the Federal stuff tends to shoot a little better in most of my guns. But as was stated, it's a trial-and-error process, every gun is different!
