RE: 30-06 bullet recommendation
For me it depends on how you hunt. I use different bullet's for different scenarios.
In my Remington pump carbine, I shoot the 200 grain Sierra Game King for reliable and accurate shooting out to 250 yards. The bullet is devastating on anything I have shot with it. Up to elk.
Im my TC Encore I shoot the Nosler 165 grain BT. They outshoot the 165 grain Sierra, so the Nosler is my choice. However I do not think the BT will outperform the Sierra, it just shoots better in my Encore. Rifle is accurate to 400 yards with no problem.
In my 700 Remington I shoot the 180 grain Sierra Game King(could be the Pro Hunter-I need to check my shelf). I have not used this rifle for a long time. The 180 was a very effective bullet. 400 yard shots were no problem with this rig also.
I like the 165-200 grain weight's for the 30 caliber. These weight bullet's have always shot better in my 30 caliber's. I found anything under the 165's just did not shoot as accurately, and also IMO was not as effective on game. Tom.
