[legend]

i plan to try some wc860 in my 7br with a 122gr cast boolit.
has anyone any thoughts,or,tried it or something close in burning rate?

I have a bad feeling this isnt going to work to your satisfaction. I did a little modeling in quickload using the lee 130gr bullet and H870 which is damn near your Wc860 and found that it will burn roughly 24% of the powder in a 24 inch barrel and give you maybe 1500fps tops. Many other powders will give you that or better velocity without the 75% unburnt garbage in your action. Quickload shows you could roughly equal the ballistics of a full case of wc860 using 4.7gr of Unique for example.


If you insist on trying the wc860 load - heavy bullet, magnum primer, heavy crimp is going to work best (you might get 30% burn and 1600 fps).

Might depend on his lot of WC860. Mine seems to be closer to 4350 or 4831 depending on cartridge/ bullet.

Talk to Buckshot. He's an expert on 860.

Thank you all.

I did try it and about half the powder charge lay in the bottom of my barrel.i lightly crimped and used mag primer.

It was very slow,about 1250 from my xp-100.

Back to the drawing board....

thank you for your responses.

It does well in the 06 and 308 class cartridges as well as the Xx57's if you are looking for a use for it.

7383 might work in the 7br - got any of it?

i do not have any ,and was just looking to use the wc860 in something.
I believe i will try red dot next.

thank you.

WC860 is good for BP velocity in my 45/70, 63gr compressed and crimped with a 500gr bollit about 1180/1200 fps, have to blow tube about every fifth or sixth shot.

thank you freightman,i do load with a friend in 45-70.

You might be able to spark it off with a booster charge of maybe .5gr of 231 or such. I have heard of others doing this in some cartridges, but never was comfortable with the idea.

With what 860 is going for now, I would just get some Alliant "Promo" powder and use that. Check over on the CBA site. I believe that some have said that it is right at Red Dot, but no red flakes in it.

I do put .3cc the smallest LEE dipper, with some WC680 and get about 150+- fps more velocity but drop your charge by the four grains of the WC860, it is also cleaner. I do not do this all the time and have went up to .7cc and reduced the load accordingly and had about 300fps but only once as I didn't like the extra recoil but most of the time I just use the WC860 and blow the extra out. You may have a little different results as both of my 45/70's have 34" barrels.

thank you all for the input.

MERRY CHRISTMAS
