Tight Bore 260 Loads?

[lencomatt]

My smith is finishing up my Badger 2013 with an Obermyer tight bore barrel in 260 this week and I have no idea where to start with loads. I've know the tight bore needs less powder but don't know how much less. I've heard as little as .5g to 4g, that's a big difference. I plan on starting with some 140g bullets, and I have some H4350 and H1000. Any starting recommendations would be appreciated.

I shoot an obermeyer 260 with a tight bore. I am using 4350. Started at 42.5 and worked up to 43.8 in a lapua case with wolf or CI primers. Wish I could find more 4350.

I'm going to try some hodgdon superperformance and a 123 AMAX (Only thing I could actually find while awaiting H4350)

You'll love the rifle.

What kind of velocities are you getting? And 140g bullets or 123's?
