.............How WC820 can be used will be determined by the speed of the 'Lot' you get. One thing to remember is that regardless which lot speed you get, the powder WILL BE usefull, and beats the heck out of paying $20/lb for canister stuff.

You just might not be able to safely milk the very last FPS or ft/lb out of the cartridge, you might otherwise be able to with the 35-40 suitable canister grades out there :-)

I got out mu RBH .41 magnum, ordered some Magma cast 225g bullets and tried 12.0, 13.0, and 14.0 grains. All seemed to group OK with more flash and recoil at the higher loads. Standardized on the mild 12.0 g until I shoot them up.

One of our favorite places to kill tin cans, an abandomed swimming pool where folks have shot since the end of WWII, is now off limits by the U S Forestry Service. Seems there are too many four wheelers and horse riders around. Goint to have to fine a new place to shoot other than punching paper.

Tell me your favorite load with the .41M and WC820.
Thanks.

I use WC820(n) for the 357Mag and the 44Mag. In my Rossi 92 chambered in 357Mag I'm using 11.4 grains with the Lee C358-180

I bought a new to me RCBS double cavity mold for their .41 caliber, 210g PB SWC bullet. Cast a batch with straight WW, lubed with Alox in a Lyman sizer @,410 and ran them with 15g of WC820. WLP primers.
With my shaky hands and old eyes the 4 3/4" RBH shot them into a 3" group at 25 yards from a solid sandbag rest. Not unpleasant recoil and much better performance than the Magma cast 225g. Group opened way up at 16g and tightened somewhat with 17g. Didn't chrony these but will in the future.
Hot and humid on the range today. 95* with 87% humidity, wind out of the NW at 12-14mph. Goint to be a long hot summer here in the South.

Yeah, it won't be much use in the .45 Auto, but it's a great magnum pistol powder.

I use 17.5 in the lever guns with Lyman's Keith. Too much for pissolas in terms of recoil for me. If likewise for you, use BlueDot at 12.5 grains. Alter the load down until you get an inch at 25 yards. ... felix

I use WC820 and also a Lee autodisc like junior1492. Just have to keep the elastemer(sp) seal changed so it doesn't leak.

as was mentioned there is a big lot to lot variance in this powder.....so always work up....my lot is 2 gr slower than aa9.

I've used 2400 data as a reference point mine might be a hair quicker than 2400 but not much.

[jonk]

Works fine for me in the .357. Does ok as a cast rifle powder for light loads as well but I can't say as it is as good as 4759.

Hi.
W/ Heavy Bullets You Don't Need A Mag. Primer.
W/ Mid. & Lt. Bullets You Do.
357-180gr. Use 11-13 Grs. In Blackhawk Strength Guns. 13 Is V. Hot!

I've used many pounds of WC820 in the past few years (.44 magnum and .357 magnum - also works extremely well in the .32/.357 Dell and .32 Miller Short in Schuetzen rifles).

BELIEVE what you have been told about the burning rate in different lots. This is NOT a canister powder. A really good way to gauge your lot is to make a direct comparison to H110 or AA #9 with the use of a chronograph.

My lot is within a half grain of H110, so I just use H110 data. If you have a lot as fast as #9 and try to use H110 data you can get into trouble VERY fast!

It's a great powder, but you must be careful.

Yep, yep, yep. I second that. I've burned up quite a bit of Pulldown WC820 from Jeff Bartlett, and all of it, each container, I had to work up loads again. Even the pulldown stuff varies a bit, but its all good powder and works great in .44mag, I've had hit and miss luck with it in .357 Mag loads.
