OAL influencing feeding I understand, but what are you guys referring to concerning "nose cavity"?

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.

I'm personally eying the Remington 110gr 30Carbine softpoints.

Would the OAL with this be too short with this bullet in 300AAC? If so, would it be OK in the 7.62x40? I'd love to get the same performance out of an AR that I can get with my 30-30.
