Ran out of my normal Bayou Bullets 124 gr coated, so picked up some SNS coated 125gr .356 bullets from Dillon when I was in the store. Same load that I normally use for my Bayou, but had 4 squibs out of 50 rounds. Bayou measured out to 1.1585 OAL and the SNS measure out to 1.1530 Crimp is .378 on the Bayou and .3765 on the SNS. Just did a plunk test (as I normally always use a case gauge not a barrel) and in my STI barrel, none of the SNS passed the test, but all of the Bayou ones I had left over did. The SNS sticks out maybe 1/8 of an inch further than the Bayou. Also, noticed that I had a TON of unburnt powder all over my arms with the SNS. I'm at a loss. Not sure if it's because the Bayou has the lube ports (not sure what they are called) and the SNS don't, but my other reloads using Bayou like the 115 and 147 gr don't have the lube ports and they function just fine. Any ideas? The single beulet is a Bayou and the two are SNS. Also, using 4.2gr Bullseye powder.
