Just piggy back other 130 grain data, and it will be very similar.

I used basic input based on data in the post, let me know what needs to be changes like barrel length, cartridge, AOL and I can recalculate your load.

Who is the bullet manufacturer? They have different ballistic co efficiency. I can load particular profile to get better data.

Well, looks like this is newer bullet and Quickload has no profile for it. Sierra does not publish needed dimensions to build reliable profile, so I can offer what Quickload has at the moment - 140Gr HPBT, 22" barrel. Use at your own risk.
