    Hodgdon H380 in the Grendel?

    Ok you load development gurus out there. I noticed in a thread that someone was using H414 and it got me thinking about H380 in the Grendel. Any thoughts? The reason I ask is I have a bunch of H380 that I use in my 308 and it just never dawned on me to give it a try in the grendel. Meanwhile I have been trying out several other powders and not really getting where I want to go with the Grenedel. Still trying 8208 and AR-comp anyway, just would be nice to have something else I can use H380 in.

    If anyone can run the numbers to get a rough starting load for H380 and bullets ranging from 95, 100, 107/108, 120, 123 & 129/130s.

    Thanks,
    Indy

    OK I was just looking at a burn rate chart (I know, I know...) and there are several "Grendel" worthy powders right there with H380. The list goes from W748, BLC(2), CFE223, Leverevolution to H380. I'm just thinking that I (and many others ?) have overlooked a good powder that some of us may already have on hand. In my precision 308 bolt gun I get outstanding accuracy with H380 and 168 SMKs.
    Just thinking out loud.

      N140 also seems to be in the very close ball park, but I guess one of the biggest determining factors for this powder in the Grendel is the kernel size. If it's too large, you won't get enough case fill. I haven't used H380, so I don't know off the top of my head.

      If it has smaller kernerls, it will be more ideal for the Grendel, as long as the burn rate is close to the powders it appears to be on Lapua's burn rate chart.

          Those QuickLoad numbers look interesting!

          Has anyone done any recent chronograph work with these bullets, powders, and an 18" Barrel?

            If it has smaller kernerls, it will be more ideal for the Grendel, as long as the burn rate is close to the powders it appears to be on Lapua's burn rate chart.
            Just an FYI, H380 is a fine ball powder! I guess I should have mentioned this before. Thanks for the quick load info. I don't get to the range as often as I would like to but I will try to do some load work with this.
            Thanks,
            Indy

              Any updates on this? I was looking at H380 too. It might be too fast with fine kernels. I would like to get the 129gr SST to 2400fps.

                I'm pretty sure most of the available powders have been tried and for one reason or another many of them aren't ideal. It's too bad the old forum is gone because I remember there were a lot of powder tests done a couple years ago.

                  I found this old thread and wondering if anyone had any success with this powder. I have several pounds that I purchased for my 22-250 but my rifle doesn't seem to like it.

                    Poli,

                    Sorry I haven't been able to work on this load. Been working out of town for almost a year and now getting ready to move. I hope to maybe give it a try before deer season. FWIW i have had pretty good luck with AR-comp. I really want to try some power pro 2000 MR if I ever see it again. The one thing I don't like about the AR-comp is that I can't get enough in the case ( may be a short throat issue with my PF upper, not sure yet) as I have to seat the bullets shorter than mag length.

                      Indy, I couldn't find anywhere any proven data for this powder, but to be honest I didn't do an exhaustive search. If I ran into anything or develop any loads I'll post here.

                        I know this is an old thread..., but I am curious if anyone has tried H380 in the 6.5 Grendel? It seems like it would be a possibility, but I'm not aware of any published load data. Appreciate any experience anyone can share with H380 in the Grendel.

                          No info on H380, but love your channel!! Congrats on scoring some H4350 btw. How's that Grendel Hunter upper shooting?

                            Thanks for the kind words regarding my channel! I was happy to find some H4350, but sad I couldn't justify spending more to buy a larger quantity. The Grendelhunter is doing a bit better with the 120 gr. Sierra Pro-Hunters shooting under an inch now using a solid rest. I'll try to get some more videos out on it soon.
