What powder for brass solids in a 500 NE?

[matt85]

I'm trying to get my Heym to regulate with Woodleigh hydro's and Barnes banded solids and ive pretty much hit a dead end with RL-15 powder. so the question is, what powder should I try next?

ive got a pretty decent load using IMR 4350 with Swift A-frames but this powder really doesn't work with brass bullets due to case capacity.

the gun was regulated with Federal ammunition loaded with Woodleigh hydro's so I know its possible... just a matter of figuring it out.

thank you

VV-N540 looks like it might be a good choice and H380

I would guess something in the burn range of H380,H4350 should work but kinda surprised the IMR 4350 does not have enough case capacity you tried. Will be following thou. As I have a Heym 500 as well it is regulated for the hornady bullets and I bought 250 rnds loaded ammo to work thru before I start handloading for it. Then I plan to switch over to the north fork solids and work up a load.

dont think i can get N540 locally but ill keep an eye out for H380.

looking at this burn rate chart has given me some other ideas: https://www.hodgdon.com/wp-content/uploads/2017/09/burn-rate-color.pdf

ramshot big game, H414, and i suppose i could try W760 (ive got some).
