I got a whelen a few months ago, and purchased 4 boxes of Remington ammo for it. 3 boxes were the old Remington High Velocity cartridges, and 1 box was new. Of the old stuff, I now have 2 full boxes of misfires waiting to be sent back, and out of the new box, I only had 4 misfires. this is better, but still totally unreliable to me. I just acquired a few boxes of the Federal stuff, but with all the rain we're having in Texas, I haven't had the chance to get to the range yet.
