Re: 6.5x284 LRH Barnes 127 Grain LRX?
Never used that powder, but here is my load for the 127.
6.5-284 Lapua Brass
50.0 grains of H4350
127 LRX jumping .030"
29" Rock Creek barrel
MV= 3140 fps over chrony and verified with dope.
They make for a devastating hunting round.
Just be careful, as this load is very close to MAX pressure in my rifle.
