Rem 7mm Mag 120gr loads

[ForneyRider]

I have H-Varget, IMR 4350, IMR 3031, IMR 4064, RL 19, RL 22, RL 25.

I am going for about 3000fps with my Sierra Pro Hunter 120gr load.

Anyone have some powder charge for these powders for this velocity?

I have 53gr of Varget data for ~3000fps.

Trying to see which is most accurate at this velocity.

As a semi-educated guess, I'd suspect you'd have to use a powder on the faster end of the spectrum to get decent results with that small a bullet and large of a case. It would surprise me if RL-22 and 25 would burn well. That's a lot of powder to push a relatively light bullet. I'd call Hodgden and find out about Varget.

Edit to add; Looking in Ken Water's Pet Loads
