Working up a load for a friend in 28 Nosler.

RL-33 is doing great with 195 Berger EOLs.

Problem is that RL-33 is scarce as hen's teeth.

Anyone tried WC872? My buddy HTDUCK on here used it in his 7mm STW with great success. Similar cartridge . . .

Looking for powder options for the heavy bullet.

Thanks!

Try RL-26, and RL-22, or IMR 7828 and IMR7828 SSC.
