I was wondering if anyone out there loads forNed Roberts pet round. I just recently bought a ruger 77 in a .257. I shot a 3 five shot group with factory rounds got about 1 1/2 groups at a 100 yards. Not to bad, but figured i could do better with reloads. I'm gonna start out with 115gr nosler bt, but was wondering what powder to use? I have plenty ofIMR 4350, but thought that might be a bit to slow burning. Any ideas?
