Any of you guys have any good loads using the 210 SMK's with H4831? I have a few pounds of it and IMR 4350, but I think these may be on the heavy side for the 4350.
Yep, 4831 will do fine, It's pretty much the same as RL22 only a bit less temp sensitive. 4350 is way to fast. I use 4831 with 190's and 208 Amax with excellent results.
