hodgdon extreme powders

Hogdon extreme powder is all I use.

Hodgdon's powders do seem to be less temperature sensitive than other brands however, I'm not going to limit myself to just one brand. I've got 23 different rifle powders and 9 pistol powders. I don't really care about temperature sensitivity. I reload to find consistent accuracy, then velocity. If I can get both, all the better. I reload and shoot year round for four different rifles/calibers. JohnnyK.

What you have read is true. Alliant RL powders are VERY temp. sensitive. I have some great loads with RL 22 and RL 25 but have started using Hodgdon H 4831 in place of them because of the temp. insensivity. My experience was I developed a load shot great with good velocity in late spring. When I shot the rifle in early winter my point of impact moved about 3 inches. After switching to Hodgdon the problem of point of impact moving was solved. My velocities are a little lower but I DO know where my bullet is going to hit.

Agree!!! My experience is that the Winchester ball powders are temperature sensitive as well. My main experience is with WW-748 and 308Win. loads developed in 50's temp and show excessive primer flattening at 80-90 temps. I've used RL-15 for my long range 223 loads with 80 grain bullets, but the loads were developed in warmer 70 degree weather, and I don't remember any real pressure variations.

Since then, I've turned to the VitaVouri and Hodgdon Extreme powders. N-140 and N-540 have given me greater velocity, and good temp. stability.

The RL powders are great powders and are very good if you want the most velocity. The H-Extreme powders are not as fast for the most part but are very temperature stable. I remember using them before they put the coating on them that makes them temp stable and the velocities were higher. I start with the Extreme powders first then move on if they do not work well which is rare.
