I pulled out my Kimber Select in 257 Roberts this weekend. It's been a while since I've shot it. First thing I did is check the campfire pet load threads and realized a pure load data thread was missing for this classic popular caliber on the campfire.

Today, I loaded up 115 Ballistic Tips with 43 grains of H4350. I've been pretty lazy with the Roberts and have used 42.5 H4350 with 115 Ballistic Tips, 120 Hot Cores, 120 Hornady HPs. I've killed a few animals with 115 NBTs and 120 Hornady HPs.

Here's a link to some info.

3 of the standard Bobs I've had including my Kimber 84 Classic Select love 46.5 gr Ramshot Hunter, 100 gr NBT or Interlock, and LR-M primers.

Ramshot Hunter has worked exceptionally well for me in the Bob.

Good luck; awesome rifle!

If you hunt where it's really cold, Hunter and H-4350 may be better choices than H100V.

If you're hunting in TX, I hunt mostly in LA, sometimes NM, H100V will be your velocity champ and holds its own with accuracy.

Yep although w/ those heavies H4831 is awesome too.

This has been my experience, also.
