You likely won’t see much of a difference in accuracy. It’ll shoot nice groups at -25deg F or 150deg f.

What you will likely see is a POI shift the magnitude of which is going to depend on how far your shooting. I can’t remember off the top of my head how many FPS gain/loss you get at hot/cold temp with this powder or its commercial equivalent H335.

If you have a Chrony graph I’d try sticking some rounds in the freezer and then firing them. Then warm up some rounds, stick them on your dash for a few hours on a hot day. Use the same load, but make sure the load your using isn’t a max load.

You should be able to graph it out and get a rough idea of FPS/degree which will show you the temp sensitivity of the powder.


Reloading...it’s like knitting for men.
