I bought a box of those 150 Hornady ELDX's and will be testing those with IMR 4350 and Ramshot Big Game.
my recipe of 150 BT's and 4350 are already delivering really good groups, but I have time to fiddle with alternatives in the off season.... and so it is with Rifle Loony's.
Always gotta fiddle with it....
just got back from the range....
I think I managed to pickup about 100FPS by switching from 150 BT's + IMR 4350 to 150 ELDX + Ramshot Big Game + mag primers, but my 5 shot group opened up from 0.5" to 1.2".
I'm pretty sure either of these will work just fine.
