Sierra 220 RN for 300 AAC?

[tiNdvenTFHwMdqKW]

Anyone using the Sierra 220 Round Nose for cheap subsonic plinking in their 300 AAC Blackout?

At $14 for 100 it's a lot cheaper than the 220 SMK.

Any reason to not use these in an 300 AAC AR? Feeding issues?

I am loading them in an AAC Remington 700, and they are an excellent choice running 1036fps with 12.2gns of Trailboss. Granted this is a 308, but they do stabilize well at SS velocity.
