280 Ackley 140 AB load to duplicate factory. Nosler TGR

[ccoker]

I have a TGR rifle that shoots the factory load to one ragged hole
I want to duplicate that load with commercial powders

Will start by duplicating the factory load
Just curiously anyone else has done this excersize with commercially available powders

Thanks in advance

I would start with MRP powder. :wink:
