Two TOTALY different things.
Abuot three months apart. I about crapped myself when the oehler said 3150 fps avg. instead of the 3050 I was expecting. I never drank the Hodgdon kool-aid, but I did expect them to be better than that.
The load is 38.0 H 4985, win 25 wssm brass trimmed .010" under, fed 210, sierra 100 grain pro-hunter.
I usually shoot rl but was limited on their data at the time, so I started playing with H 4895 with 100's and h 4350 with 120's. I have really limited data on how the 4350 has done with the 120 speer and a 215 in that rifle, but I'd put $50 on it being under 30 fps between 20 and 80 degrees. I think H is still getting temp. swings with certain powders and you really have to try them out and not just believe.
