25-06 with AA 3100

[Posit]

Anyone tried and had success with Nos 115g BT and AA 3100? Its one of the three powders listed on the Nosler site. Any known rationale for listing these three? I notice the three loads are slower than most loads for 115g-120g bullets (2581 to 2884 fps), and the load densities are relatively low--?

Secondly, in old posts, I see several people were ready to try Retumbo and IMR 7828... anyone have positive results?

Having some difficulty working up a consistent load for a 25-06... tried the popular solutions... looking for tested alternatives.

IMR 4350 works really good for the 100 115 and 120s but retumbo is looking better higher load densities. the 120s like 58 grs the 115 like 58.5 and the 110 gr ab like 58.5 and thats with fed 215s and you might try RL 19 works good for the 85 and 100 gr bt.

Thanks for the load data and comments. I really want to use the 115g Noslers in this rifle - but if this doesn't work, I'm gonna try something different... maybe this rifle just doesn't like them.
