RL17 temp stable?

What's y'all's experience with RL17? I know that a lot of people say that alliant powders are not very temp stable, but on the bottle of 17 it states..."consistent max velocities in extreme weather." Has anyone had good/bad/ugly experience with this stuff?

Just more internet BS...

Just because some powder is claimed to be "more temp stable" does NOT mean all other powders are now suddenly temp unstable.

I bought RL17 for use in my .260R. Have had excellent results so far.

So far the only thing I've used it for is my 243 Winchester. I am loading Barnes 80 grain TTSX's and was able to reach Barnes safe max charge with no signs of pressure. To my surprise accuracy at those levels is outstanding, sub MOA. I like it

I've used it in my 260 behind 120 gr Nosler Ballistic Tips. The load, about 1 grain under max, shoots real well. If I remember, I had to look around a bit to find out what the max recommended load was.

I've gotten on few site's and read post about R-17 and problems with temp mostly from 80 to 100 degree.

I like to spend about year or so shooting rifle before I start hunting with it so lets me go thru our winter to summer shooting here in Co. At our range benches are cover so no direct sunlight but I've shot R-17 in 80-90 degree in 280AI and 284 with no problems at the range. couple years ago was slow hunting antelope and ranch had some PD's on it so set up bench and shot few on off for couple hrs with 270WSM was shooting R-17 and temp was in the 70's and no problems. I did keep my ammo in a cooler and watch barrel as to heat.

I've done the same with other powders so didn't do anything new.

Last year I had the 280AI on 4th season elk hunt temp was 15 below no problem with R-17.

I'm sure some may of had their rifles in direct sun and cooked their ammo and had problem with it.

I love it

Thanks for the input guys. I put it through the crony yesterday and with absolutely no signs of pressure, 52.8 grains (alliant says max load is 53.0) and a 100 grain TTSX it's avg fps 3,417! Accuracy average was 0.615", good enough to kill some deer. I leave Wednesday, hopefully will have some good pics when I get back!
