I recently bought a box of Lyman .41 gas checks because the .416 ones from Hornady do not work right with the bullet design I have (It's a Saeco TC design). I've never used Lyman gas checks before because the Hornady's are more readily available where I live and they cost less to boot. The question I'm getting to is: Is the crap quality of Lyman gas checks the norm? Or did I get a bad box of them? The gas checks need to be culled before they can even be used. There are some (about 8% or better) that have the sides torn off in one spot from crap manufacturing. Many have the pieces that look like they should be on the previously mentioned checks mashed into the cup, which are difficult to remove. The sides of cup are not even close to even on many of them. I've always used the Hornady's and they appear to be a much higher quality check, especially for the money. Are all Lyman gas checks crap?
