Helping a friend build a 260 for long range hunting school and future hunting trip. We put on a 24" CBI 1:8 twist barrel. He has chosen 140 Berger Hunting VLDs and has several boxes. We found a good supply of 260 Lapua brass. I have tons of primers to share. Redding S-type FL dies with the competition seater are in hand.
Now the hard part.... since H-4350 is unobtainable (in my searching efforts recently) what powder would guys suggest we try? Keep in my that he has a 24" barrel - which is a sub-nose by my definition. For a hunting load we are wanting to have near a max velocity with a given powder. I have or can get the following:
IMR-4350
RE-15
RE-17
RE-19
IMR-4064
H-4831SC
What would you suggest. Once we work up a load, he wants to go to his long range shooting school with 250 rounds pre-loaded. I am a bit concerned about the elevation swing. We are at 800 ft and his shooting school is +7,000 ft.
Thanks for any help, Tim
