    Reloading .375 Ruger

    Anybody done any loading for the .375 Ruger. I've read that you can't duplicate Hornady's factory speeds with the powders currently available to the public (at least in the 20" Ruger Alaskan). I have a 300 gr. factory loaded bullet that lodged in the spine of a carabou at under 200 yds. It was intact, mushroomed, and weighed in at 150 gr. Not exactly the "anything on the planet" performance they claim. I pulled all the bullets from 3 boxes of factory 300 gr. ammo, and weighed the powder charges for all 60. They ranged from 85.5 gr. to 88 gr. and everything in between. Not exactly the height of precision. I'm going to reload with A-Frames, but the only powder tip I've gotten so far is Reloader 17. Any other options out there? Thanks.

    What factory ammo were you using? I wouldn't be too happy with those results either.

    Are you planning on using the 300 gr. A-Frame? If that doesn't work out, I'd recommend the Partition. Varget and RL15 should work well for you.

    Keep in mind on the powder weights, they might be going off of mass instead of weight for each charge. It's just a different process. I have been switching to it with my precision loads and have had improved accuracy. I can see a the +- 1.5 gr. with a big load like that.

    Drhorsepower, can you explaing this volume thing? Im interested and this is the first time I have heard of it. Maybe im behind times but I load everything to exact powder charges.

    A lot of benchrest shooters take a 45-70 case or similar, braze a handle on it and trim the top of it to hold a specific "volume" of powder. They simply fill it with powder, take a straight edge and scrape off the top, and fill the case of desired cartridge. They do this instead of weighing each charge. It is interesting. I have been dropping my charge and not weighing it out of my .243 and .220 swift, I obviously weighed the first few to set up my dispenser but after that just dropped the charge. I shot them on paper and there was a slight improvement in accuracy.

    The name of the book is, "The Benchrest Shooters Primer".

    A great read

    Charging by volume can be really accurate. That is how a powder measure works.

    Powder dippers work off volume also:

    I do all my black powder loading (shotgun, rifle, pistol) by volume. I think it depends a lot on the powder you are using. Larger granules have more airspace between them than powders such as ball, thats why they have come out with "short cut" powders (eg. 4831sc). Dispenses and packs more uniformly. I also believe it burns more evenly. For my regular loading I use the big RCBS (can't remember the mod#) automatic powder measure. After you program it, dispenses the powder automatically every time you empty the pan. Weighs to the 10th of a grain. Extemely accurate and fast!
