With Rem. 700 sendero rechambered in 300 WSM
I chronyed the following loads yesterday with 180 SMKs using WXR (THESE ARE HOT) Accuracy on both was less than an inch at 200 yds
70.3 gr WXR with Fed 215 mag primer - 3050 fps
70.5 gr WXR with Fed 210 match primer - 2975
I will probably backoff to 70.2 with the Mag Primer for final loadings?
A side note was that there was only a 1" drop from 100-200 yards.
The best I could get with H4350 was 2950 before pressure signs start and accuracy went bye, bye!
