[QUOTE="barnesuser28, post: 846056, member: 43468"] I have tested H4350 in my 284 win in 73-103 degree temps. My load has an es of 2 fps over four shots, according to the magnetospeed, done twice in the same conditions on the same day. This was done in 73 degree ambient air temperature, with the ammo and gun at the same temp. I then tested the exact same load in 103 degree ambient air temps with the ammo and gun at the same temp. There was a 5 fps change in average velocity over 5 shots with es staying at 2. Sd was 1.5 fps. Accuracy remained the same .5 MOA. [/QUOTE]
