300blk-lee 155-wc844-wc846???

[arjacobson]

I am in the middle of a 300blk build and am looking for load data. I have quite a bit of wc846 and wc844 powder. The bullet I will be using is lees 155gn harris design with gascheck. I realize there are better powders out there for 300blk but has anyone worked up ok loads with the above mentioned powders?

I too have a bunch of WC844 on hand. I thinks its going to be too slow for a 300 Black out load though. I have heard of people getting some of the heavy jacketed bullets to fly with these powders. But I havent tried it yet.

Try, you never know. It's a slower powder for the case capacity so treading new ground should be safe enough. Please post results as inquiring minds want to know!

I got 4895 and pulled 54R powder to work with 155 gr bullets in the AR I dont see why the two ball powders you mentioned wouldnt . Try around 17 grs with a mag primer . Vel. wont be real peppy but it should work enough to cycle the action

How did you get 32 grains of any powder in the 300blk case? I'm surprised it held that much.
