26" barrel 1-8 twist.

Looking for pet load data.

I plan to use a 140gr Accubond & 215F primers

I have RL25, RL22, RL19, H4831SC, IMR7828, IMR4831 & IMR4350 in my cabinet to choose from.

Where should I start?

Thanks

I also have a .264 and am going to be using the 130gr Accubond. I have Retumbo, RL22, RL25, H4831, 7828SSC. Been hearing that Retumbo is a good powder to use.

I have the M70 Supergrade in 264. It loves 140 Partitions and Horns on top of 65g Imr 7828 w/ a Fed 215. Have not chronoed it yet, but I love the way it groups.

I started with the H4831SC and 140 sierra match king and that shoots well in mine. Like the group, not going for max loads, have not chroned it either.

Next going to try out RL25 and N170, with same bullet (sierra)

On edit: actually I remenbered now I picked up some US-869 that I am going to try next.
