Having done a lot of load development with that gun I knew that the most accurate powder was RL- 25.
In your particular gun perhaps,but in another rifle of the same brand and exact model,another powder might be more accurate.
I could understand using a different weight charge, but different powders????? I highly doubt it. Especially two powders from the same company RL 22 and RL 25. I reload with my father in law for the same gun and his loves RL 25 as well. Also, when your talking about a big case like the 30-378 you want a slow burning powder. RL22 is too fast for that much powder in my opinion.
I think nosler is holding on to what they think is a secret. Why use RL25 in custom ammo and say RL 22 is the best in the book. It doesn't make sense.
