There is couple of guys at the club who ran out and bought the teknys series as soon as they came out a couple of years ago. They seem to have feeding problems on the second shot. They tried everything polishing and grinding (one's a machinist) and what they came up with is this: load chamber, close bolt, load mag, RELEASE BOLT AGAIN ( so shell is sitting on top of the lifter ready for the second shot ). Does this sound right? they say everyone does it.
