I have used it and it is my go to powder for my Grendel with 25grs 130JLKs IM hornady brass, ad wolf SRM, not showing pressure signs and am at about 2300 out of a 18" bbl so you should be good with lighter bullets. 107 SMK work well with it. The 123's CC and it did not do well out of my gun nor did NCC and 8208XBR at 28.5GR.
