New To Reloading Question

[PeteS]

So I've never reloaded before and I'm starting with 6 ARC. I understand the basics of it but I have a question. My rifle likes the Factory Loaded Hornady 108gr ELDM and the H Black 105gr BTHP, but I keep getting high ES with both 30-35fps ES with the 108gr and 45-50fps ES with the 105gr. I'm assuming that's why I'm getting flyers, cause I'm not sayin I'm the best shooter in the world but I know it's not me or the wind. So I would like to replicate those factory rounds just with control of the amount of powder. I'm gonna pull some of the factory loads and get a guess on the powder but it will be a guess, especially on what type they use. I've heard alot of success with Leverevolution and CFE223. I'll take all the measurements off the factory loads and get a idea of COL and case length and all that. I would appreciate some advice/opinions. Thanks.
