Thanks Jax - will look into availability of those powders. Mines a 26inch barrel.Hornady use RL-16 in their 108gr match ammo. I’ve got a tub, but not got around to trying it yet. RS62 is what I currently use with good results. RL-17 may be better in a shorter barrel perhaps, but going by what others say, it’s harsher on the barrel.
The attached is factory Hornady 108gr. Bottom target is 3 shots
Nice shooting!!
