RE: 30-06 bullet weight on elk
I would consider the Federal High Energy 180 grain Nosler Partition. This load chronied out at 2831 FPS in a 22" barrel in a recent article.This is faster and flatter than most competative 165s "claimed" velocity from a 24" barrel.
If you prefer a 165 I would try the High Energy TBBC or the Hornady Light Mag with the Interbond. Both the Interbond and TBBC do an excellent job of retaining weight, but the Interbond carries energy better downrange. The Interbond is tougher version of the SST bullet Heeze Gut Shot recommended.
This stuff is expensive, $26.00 for 20 rounds.
