I'm waiting on my RPR in 6mm, have you loaded any of the 115's?

What are your SDs and Esso for the 4451 powder? Curious cause mine were not as good as I hoped but it was fairly accurate as well in my RAP rebedded in a Boyd's At1 stock.

My ES was around 10fps with the 4451. I had around 5fps ES with the n160. I recently got a magnetospeed and I will be doing more load development with a few more powders in the IMR range and the Vihtavouri powders.
I unfortunately do not have a lot of powders at my disposal as I live in South Africa. I want to push loads a little hotter. I shot a sub .1moa group yesterday with the N160 load but I think it was luck as I am a consistent submoa shooter, not sub half moa or even sub .1moa shooter. I have an annealing made perfect machine on its way and I believe it will lower the ES even more.

I have been looking for the 115s but I cant seem to find them where I live. I will be doing a bit of load development with the Nosler 105 custom comps, 105 RDF, 107SMK, 110SMK and the 105 lapua scenars. The RDFs are looking very promising. I have started moly coating all my bullets and I have gained quite a lot of velocity as well as lowered the pressure. I will keep posting updates on that as I have them
