I know nothing about WC 855, Win 780 is WAY TOO SLOW for the Garand. Most use IMR 4895 or H4895, IMR 4064 or Hodgdon Varget is another choice. I like Win 748 becuase it meter well (it is a ball powder) and I have very good accuracy with it. Win 748 is on the slow end of the acceptable powders for the Garand, the IMR and Hodgdon 4895 are on the fast end, but are not interchangable. IMR 4064 and Varget are in the middle. I had similar results with IMR 4064 but chose to use Win 748 because it meters so consistently. I use Large Rifle primers with 4895, 4064 and Varget - Large Rifle Magnum primers with Win 748.

As for the WC 855, I do know that would be either a pull down or surplus powder. They are usually less consistant from lot to lot. Commercial offerings are more consistant, but not identical from lot to lot.

I also should mention, Hornady has a section speciffically for the M1 Garand - DO NOT use standard 30-06 data, that will destroy the Garand!

I have reloaded before with some of thr powders you mentioned.I just found a guy that had these surplus powders for sale cheap and he said they might work but I hadn't seen any reloading data on them.I had gotten the reloading info for the garand from Hornady .

Try this Iggy; Do not use maximum 30-06 loads. They may damage your Garand. Good Shooting.....

Ceresco, I agree. My loads for the Garand seem to fall around 45 to 46 gr of powder. But Winchester 780 is a very slow powder. It is slower than 4350 and faster than Hodgen 1000. It would require more than 50 gr to get enough speed for the bullet, closer to 60 gr. That would create too much pressure for the op rod uless one had an adjustable plug.

Based on info from another member, I tested two lots of 7831 (an extremely slow powder) using a McCann plug. A 30-06 case full produced the same gas impulse as HXP. I believe the entire pressure range of the 7831 was low enough to be safe. Much unburned powder, as expected. I mention this to illustrate the dearth of real, quality information on this subject. Still waiting for the credible reports of widespread op rod damage. It really makes little sense to go outside the normal loads for the M1. There are many tested and proven loads to be found and all the componets are readily available. Good Shooting.

Is it possible you are speaking of Win 760? Not 780. Maye I'm crabby about this but BE ACCURATE WHEN YOU ARE TALKING ABOUT A SPECIFIC POWDER. Sloppy references will mislead the unwary. Yes, 760 is too slow. I would also question the statement that Win 748 is slower than H4895, IMR 4895, IMR 4064 and Varget. Win 748, BL-C(2), and WC-846 are all pretty much equivalent load-wise. I would consult a number of loading guides before drawing any conclusions.

Happy Thursday!

There is years worth of published data which contradict that latest burn-rate chart. As I said, don't depend on any one source. Look at the loading data itself......what charge gives you what velocity with any given bullet weight in any particular caliber. Of course you're free to believe anything you want. It's a free country.
