    I swear many years ago i used this in 223 and 308. I cant find load data for this powder. Maybe I am loosing my mind or loaded something else back then, but can anybody check and see what you find. Start load and max load. If you do find something can you please tell me what book you found it in. Oh 55gr in 223 and 150 or 165 in 308.

    Thanks in advance

    In my Modern Reloading 2nd Edition book I found this...

    .308
    150 Grain Jacketed Bullet--H380--47.0 Start Grains---51.0c Max Load

    I was not able to find any more data in my book for the other caliber or bullet weights.

    Checking my Modern Reloading 1st Edition Book I found load data for the 223 and the 308

    .223
    55 Grain Jacketed Bullet--H380--28.5 Start--28.5 Max (not a typo)

    .308
    150 Grain Jacketed Bullet--H380--44.4 Start--51.0 Max
    165 Grain Jacketed Bullet--H380--42.8 Start--48.0 Max

    This should get you going in the right direction:D:D

    Thats because the starting charge is a compressed charge. Much like stuffing 27 gr of reloder 15 into a .223 case (which is one of my favorite loads and its not even max, but it is compressed). And the reloder 15 has a listed max of 28 gr. for the .223. I cant figure out how the hell they get the extra grain of powder in there:eek:

    My Lyman manuals have H-380 listed for .308, not sure bout the .223. I have used it several times for my .308 with decent results. I have had better results from other powders though. My last load of my cases gets loaded up with 147g FMJs for plinkin, and H-380 is what is used. I save my good powder targets and huntin.

    Hodgdon, the supplier of H380 doesn't recommend H380 for 223. They recommend, among others, H335, which is one powder I regularly use for 223 and many other cartridges in the small to medium class.

    For heavy bullets (75 gr) in my AR15 clone with a heavy varmint barrel I use VittaVuori N140 which gives superior results but is hard to find (finally found two one pound containers, the store's last, after nearly a year of looking in every dealer and searching the Internet).

    As an aside, buying powder off the internet is expensive because MOST places nip you for the Hazardous Material Shipping Fee which often is nearly the cost of the powder itself.

    The hazmat fee is the same if you buy one pound or twenty. stock up and it's not a big deal. Get together and order with a couple of buddies if you have to.

    JLA: I consider my good powder to be what I get the most accurate results with. H-380 works, but not near as good as Win 748 or IMR-4895, 4064. With H-380, 3/4" groups are the best I have gotten. I can get a lot better accuracy with the others. For plinking, H-380 is fine for me.

    Hi:
    First post. I am currently reloading 32WS for a pre 64 Mdl. 94, carbine.

    I am also intending to reload for a pre 64 Mdl. 94 chambered in 25-35. Not a lot of reloading data for this one.

    I am currently using Win 748, 32.58 Grms. I noticed the member identified as "bntyhntr6975" mentions Win 748 and I was curious as to whether he may have any further data possibly relating to the 25-35 Win.;)

    32.58 grams = 502.786235 grains, somehow I dont think anything chambered in a win 94 levergun is gonna hold that much powder.

    If by Grms you do mean Grains instead of Grams, how are you measuring the .58? All reloading scales im aware of only measure to the tenth of a grain, and youre claiming to measure to the hundredth.

    In the lyman 49th reloading manual the .32 win. spec. is listed with 170 gr bullets only and Reloder 7 as the recommended powder.

    IMR 3031 is a recommended powder for the .25-35, though data is quite scarce.

    I think by dropping it through a straw. A copper tube afixed to a funnel with a flared end to cover the mouth of the case

    Hi:

    To JLA I appreciate your comments. First let me say that the 32.58 grains of Win 748 are for the 32 WS, not the 25-35Win.

    At the online Load Data site the recommedded powder is Win 748, at a load of 36.2 grains. I reduced that by 10%, multiplied by the VMD of Win 748, and came up with the figure of 32.58 grains. I am not using a gram scale. I have the Lee Powder measure Kit with the graduated scoops. The final number derived from the 32.58x.06550VMD is 2.13. The closest scoop is the 1.9 scoop, which I ued to load the brass.

    I think I am on solid ground, but I defer to thos more learned than me, and would appreciate your comments.

    While the LEE scoops work, using them is no way to an accurate repeatable load. There are many scales on the market, both mechanical beam type and digital. Do yourself a favor in buy one. It is the only way you are going to be able to make consistent reloads at load levels different from the available scoops. With the math required and the looking up in tables etc. you are just looking for a mistake.

    I agree with LD. Scoops may work most of the time, but there's no substitute for a good beam balance. You really should spend the bucks on a decent scale such as Lyman or RCBS.

    I've used the scoops several times when I didn't want to switch the thrower over and I was only going to load up a handfull of something. They are great for gettin ya close, but I only used the scoop to put it over on the scale, and trickled in what was needed. I really like my Lyman digital scale (as long as you leave it plugged in so no warm up is needed or recalibration) but theres not much guessing with a good old balance beam. It either works or it don't. A good scale is just something you really can't do without.

    I too use the scoops only to get the initial lump of powder in the pan of the scale, the trickle in the rest to bring it in to a perfect balance.

    The Lee dippers are ok for plinkin ammo. And by your explanation you are on solid ground. Shouldnt have any issues with the ammo loaded that way.
