Would you be interested in selling what you have left?Sorry, I have less than half a pound. I tried RL 22 for load development for my .338 WM, for 250 gr Interlocks and Barness TSX's. Prefer H4831SC, for both 225 and 250 grains. I know it's not right next door in terms of burn rate, but fairly close. Have you thought of H4831?
I see from a burn rate chart that's right below Vihta Vuori N165, good to know, especially with it being more readily available. What are you shooting with the 7828?Don't know what you are shooting, but IMR 7828 has worked well in guns that like R22 for me.
And it has been available.
You already know this, but they are not interchangeable load data wise.
I have used it in a couple 300 Win mags, a 28 Nos., a 30 Nos. and a 25 PRC.I see from a burn rate chart that's right below Vihta Vuori N165, good to know, especially with it being more readily available. What are you shooting with the 7828?
