    I know H4895 is a forging powder for reduced loads which will give me wiggle room on the low end of the charges to start. However im not sure H4895 is the best powder for accurate 308 loads.

    Open to suggestions. Til then, happy safe loading!

    Just wanted to say thanks for the pm Forrest r . i really appreciate that message.

    Also thank the pioneers and all the contributors to this thread and others like it. I am exited about this journey!

    Molds shipped..due this week. Hopefully some results when i get a good day at the range.

    Read through the whole thread . I know Lee can be controversial at times but he has always sworn that the best cast bullet accuracy comes right when the firing process just slightly exceeds the yield point of the bullet alloy.

    I was pondering a swage die made from part of the barrel itself, it might allow controlled swaging of the bullet with rifling on the nose . One can order a barrel longer than 27" blank (intended to finish 26") and specify that the added material be on the breech end, making the 1.2" straight section longer. This would allow the bump up into the rifling form to be a slow controlled process....the exact throat could be duplicated as well.

    Forrest, 5744, and varget both have worked well for me in 308w. Word of caution, the crnograph. May not give the best max load information. In my guns the measured velocity is 150 to 350 FPS faster with pc compared to Lyman’s velocity for given loads. I think you will be pleased with results!

    What is not to understand. Powder coating typically yields 5% increase in velocity with the same load. I discovered this back when I got into PC in 2012 when chronographing know loads using other types of bullets. When I made mention of this I was ridiculed. Now Federal has prove it and more in their testing.

    I understand perfectly, it is you that misunderstood I was only bumping the thread up to keep it current.
    Having a new-found curiosity about PC, I was hoping to see if anyone had anything to add to this conversation.

    Sorry, I guess I was the one that didn't understand.

    I personally think "Bama" has pushed the envelope as far as getting accurate full power loads out of cast rifle bullets. His bullets and gas check seating are the best I have ever seen. A polymer Jacket is definitely the way to go and I think the only direction for improvement is complete swaging to uniform an imperfect cast bullet, which Bama's process has broached on. But that is just my opinion.

    Bama has pushed the PC and concentric the most, Avenger has gotten HiTek to HV in rifle and Waco is ringing steel @ 500. Lots of progress in just a few years.
    Whatever!

    IIRC Waco was using Lars 2500 lube in the video, .308/ 10" gong @ 500 yds..

    Just finished reading this entire thread. Lot of good info here. While I do not have a chronograph … yet, I intend to use this info in loading my rifle boolits. Already using Smoke's powder (clear) for revolver and pistol. Big Boomer

    Kudos for reading the whole thread, it is quite lengthy. I bought a chronograph years ago, but put off buying one for years before that and wished I hadn't. I will say this, if you get serious about accuracy you have to have one.

    Secondly, once you decide to open your wallet go all the way and get one that supports a printer and get that as part of the package. If you use it you won't regret the purchase.
