Will need data for H 4831 and WC 852 powder.

I've reloaded for less than two years, and have only used IMR 4064.
Even though the friend has older reloading books, which might include these two main powders, it would nice to be able to use Google to find min. loads as with 4064.

Found just one chart under "Handloads.com". How good is the source? Is there another with which to compare?

My loads will always be at the "published minimums";), for both the 150 gr. .311 bullets for Enfields (".303."), and 168 gr. bullets for the Spanish FR8 (.308: quite familiar with issues...).

By the way, the WC 852 is in tall, narrow bottles of opaque beige plastic. The labels say "Similar to H-380". Does that mean that H-380 data can be used for WC 852?
"Handloads.com" lists nothing for WC 852 or H 4831. The WC bottle labels look old, but the 4831 labels look almost as new as my 4064 bottles.

Can't help with the WC 852, but you won't find data for the 4831. It's too slow to be suitable for those cartridges.

Here is a link to a burn rate chart, and it lists two different burn rates for WC852, one is similar to H380, like the canister that you have, and the other lot of WC852 is similar to the 4831 family. All are likely too slow to be efficient for the calibers that were listed, but the H380 burn rate version could be used in them, if you can find listed loads that you can trust.

Here's a couple H380 loads for your calibers.

WC844 (H335) and WC846 (blc2) would be much better to use if you are into surplus powders.

Stick with IMR4064 for the best results in the calibers mentioned.

Loadbooks USA lists H4831 loads using 150gr. and 180gr. lead bullets.

Back in the 80’s several 90,000 lbs lots of WC 852 were sold by the Government. The jugs I bought came from GIbrass http://www.gibrass.com/

My lot came with a lot acceptance sheet which had this data:

30-06 Govt Loading Data: Lake City case and Primer, 60.1 grs
WC852, 152 gr Ball M2, average pressure 40,200 velocity 2750
Lot BAJ 47287

Each lot has a different burn rate. I saw data for another lot and my lot is a slower burning lot and takes more powder for the same velocity.

Accurate Arms bought a 90,000 pound lot and sold theirs as AA2700. Their powder has a quicker burn rate than mine. That original lot is gone but they continued to sell newly made powder at the same burn rate.

Given that, you must work up your own loading data. Such as I have done.

I am attaching my data for the 30-06 and 303 Brit, but be aware, it will be a total fiction for you as your lot has a different burn rate.

My old Lyman book has 3 loads for H4831. It's for 180 gr HPBT and 190 gr HPBT and 200 gr HPBT. Starting loads are at 45 gr. Max at 50.5, 50, and 49.5 respectively, max loads are compressed.

Nothing on WC 852

Thanks very much.
Some targets are paper, but most of my targets are plastic bottles at up to 50 yards.
As I don't yet reload for the Garand (fast burn needed for op rod), burn rates might not be an issue for
juice bottles at 50, or concrete blocks at 100 yards.

Will check those other websites. If there is no luck there, this coworker/ friend has reloaded for decades and will find a solution (Annapolis grad. and later on the Navy Marks. Team).

My lot of WC852 and the other lot acceptance sheet I have show that for those lots, WC852 was tested for use in Garands.

This is a powder which our normal "rules of thumb" for Garand useage do not apply. Even though WC852 is a “slow” powder, by the time it got to the gas port of a Garand, the port pressure is correct for that firearm.

If I did not have the lot acceptance sheet, I would not have used my lot of WC852 in my Garands. It is unfortunately, far too slow for M1a’s.

The rule of thumb of using nothing slower than IMR 4064 and nothing faster than IMR 3031 should always be used when you don’t know anything about the pressure curve of the powder under question.

I don’t know about your lot. You can tell if a powder is inappropriate by the violent ejection of brass. At least compared to IMR 4895, the “standard” Garand powder.

You can find H380 and H4891 308 win data in Lyman 49. Handloader #60 has some H4891 303 Brit data in it. The only 303 Brit H380 load(other than the ones already posted) I could find was 41.0gr under a 174gr Hornady RN for 2300fps.

There usually isn't any published load data for surplus powder like WC852 or any of the other WC powders either. Like said above, you can usually get data from the reseller of the surplus powder when you buy.
