Timely question, I just received a new 300wsm from Whittaker's. I had a 300wsm previously and it liked 180gr Partitions (Thanks Brad) with H4350.
I still have some of the Partitions as well as 155gr Scenars, 168gr TTSX;s, 165gr Interbonds that I will try. But , I want to try the ELD offerings due to the performance I'm getting out of the 143ELD-X in my Creedmoor.
Hopefully someone here has some experience to share.
GK
My brother,
I had mediocre results with the 155 Scenars, decent groups with 165 TSX and have settled on 165 Sierra Game kings for all around purpose, mainly range/play time and cost being factors.
65 grains about .010 off. H4350
Don't know that I've really witnessed any great changes in any small change I've made with any load with the .300wsm.
