New 300WSM

This is my new 300WSM. Wasn't sure I was going to keep it since I have a 300WM on the way, and plans to build a 338LM, but it shot so well the first time I took it to the range I have decided to hold on to it.
Built by John Whidden
Rem 700 short action trued and modified to feed the WSM
PT&G bolt with M16 extractor
Seekins bottom metal with DBM. This one is a 5 rnd. I have a 3 rnd on order
Hart #5 SS barrel at 26" with 1 in 10 twist
Holland QD brake
Oversize recoil lug
Jewell trigger at 2.5lbs
McMillan HTG with wheel adjustable cheek, and 4 flush cups
Pillar bedded
Leupold 20moa base with Mk4 rings. Base is bedded with epoxy.
NF 3.5-15x50
Weight is 12lbs without the bipod
Loads: Norma brass, 215m primers, H4350 powder, 190vld Bergers (hunting) at .012 jump
Started at 62.5grs and went up to 64.0grs.
Best group was at 63.5grs at an average of 2870fps. I think I'll stay there.
I shot 3 rds of each load at 100yds instead of doing the ladder test.
So far I'm very happy with this rifle. For now, I will stick with the 190s at 2870.

    Nice rifle. If I ever go back to the 300WSM, I'll be using the 185 Hybrid.

    Thanks for the replies. John Whidden used the 185s to test the rifle and got around .33 moa using N165. I don't have the other data on those loads. Using my ballistic calculator it seems the 190s still have an edge. I'd like to see some testing comparisons to see it it's worth testing the 185s in this rifle.
