Gel testing 300 AAC BLACKOUT

[Expatriot]

Why the omission of the 110 Sierra Varminter?

The very short bullet creates feeding issues. I didn't see any problems related to the large nose cavity. The issues I saw were related to the OAL of the loaded round. The bullet is so short that it is difficult to load to a decent OAL where it will feed reliably.

The jam I found most often was the base of the round diving into the mag and the round ending up jammed vertically between the bolt and the barrel extension.
