RL22 Temp Sensitivity findings

[goodgrouper]

I shoot Rl 22 in my 338 and last time I chronoed it she was shooting 225 accubonds at 3304 and the temp was 65 degrees.

Went out yesterday and chronoed it again for an upcoming hunt and the temp was a balmy 36 degrees. Speed was 3297 average. Not too bad! I've seen H1000 lose more than 7 fps in temp swings.

I have seen similar results w/RL25. The temp differance was near 80 degrees and had only 40 FPS gain. Funny thing was that the faster load was the cold load. -10 F. ???????

Ok , i have RL-22 and H-1000 powders for my 300 RUM , I have tried both and the RL-22 made a group of .5'' @100 yards ,and the
H-1000 about .75'' @100 yards, both in warm temp. Now where I live and hunt the temps dont get too hot but they get very cold so in your opinions what should I use ? I personally wanted to use the RL-22 because of its great accuarcy, but I dont want some thing that could be dangerous on a hot day.

Neither should be dangerous on a hot day so long as you didnt develop the loads in 20 degree air and take it to 120 degrees. Also it depends on how hot your loads are to begin with. Either powder should be fine from cool to semi hot temps (30-85 degrees).

i would shoot both in colder temps to see which is best. you're in Canada and colder would be the norm. i've hunted a fair amount in Saskatewan and i was more concerned with the POI and of course, if it would go bang.
