Without knowing which bullet you are interested in shooting, you will only get generalized responses. So, in general, H380 is a powder with a burn rate that is suitable for the 308 Winchester's case capacity.

Please consult a reloading manual or online resource website for further information. Sharing of actual load recipe details is not "wrong" but you will be far wiser to find a documented load and work up from the minimum charge.

Sorry guys Im not looking for loads but if this powder is used for 308. There doesnt seem to be a lot of listings useing h380 and since in my area its (h380) less costly than varget. I shoot a rem 700P with 168 grain amax's and sieeras in 168.

H-380 is a very good ball powder, I've used it in 22-250, 257 Roberts, 243 7-08, win, 35 Whelen. If you need data and can not find any call hodgdon or check their web site, they'll be more than happy to help you out.

Preaction, I'm sorry but H380 is NOT a good powder match for the .308 Win.

Check out this link---http://data.hodgdon.com/cartridge_load.asp

That is load data for Hodgdon, IMR and Winchester powders which Hodgdon lists as acceptable for the .308. You'll notice H-380 not listed.

Not surprising that it works better for the heavier pills as it is slower burning. There are better powders for sure, but the Sierra link shows what it's such a great cartridge-- very forgiving and versatile across a wide range of powders from the fast to slow end of the "medium" range. Thanks for the link.

Lyman's 49th lists H-380 for no less than 6 different bullets. It's a little on the slow side, but still perfectly suitable for the 308 Winchester.

preaction,
As broom_jm pointed out, just because Hodgdon doesn't have data for it does not mean
H380 is not suitable for loading .308. To the contrary, in my opinion H380 is an excellent powder choice for the 168 gr. match bullets. I have had very good results ( accuracy, and consistent velocities) with H380 in a number of cartridges, .308 among others. My suggestion to you would be to buy a current reloading manual from the bullet manufacturers of the bullets you use. In your case Hornady and Sierra. Sierra's fifth edition has data for the cartridge/bullet/powder combination you have posted about. I have had hangfires using standard large rifle primers with H380, I've not had a problem since I started using only Magnum primers with this powder.
Hope this helps, Ron.

Thanks for the information. I do have 4 of the latest reloading data books. My reading of fourms has always led me to ask questions. I am always fearful of coming upon a guy that reloads rifle cartriges with pistol powder and oatmeal in order to save a few cents a round on reloading costs. I know this is not one of them but Im sure everyone here knowes of what Im speaking of and also would like to avoid the same. So lucky me I have never felt bad about asking questions, and thank you all for your help, paul.

I'm sorry if I was off base on my recommendation. Since the manufacturer of the powder doesn't list it, just figured there was a reason. When you look at Hodgdon H-380 containers, they don't list any 308 loads as being cartridges that powder is ideal for.

Checking in the Hornady manual there is no loads listed for the H380,
Sierra has loads listed for the full range of their bullets however until 165gr. and heavier, those loads are running some FPS slower that more optimum powders.

I would get the rest of the reciepe just for the heck of it. At 46 grains it should be a safe charge.

H380 doesn't look like an ideal powder for the 308 Win. It is listed in Speer #12 for 150 gr+ bullet weights, but way down the list for velocity. It works great for 58 gr bullets in the 243 Win, if that is any indication at all.

I would note that H380, when listed, is usually the slowest-burning powder on the list and even with compressed charges, is not going to deliver best velocity. It is suitable, but powders just a little faster on the chart (like 4320 and Varget) would get you better results with fewer grains. If all I had on hand was 380 and I just had to load up and shoot, I wouldn't hesitate.

H-380 is THE powder for the .22-250 also!

By checking-out the charts DCAMM94 has posted, the best powders, for the .308 Win is: Varget, IMR-4320, IMR-4064, WW-748, plus a few other listed.
