Home Forums Reloading Big Game Rifles So what happened to RL19?

Don't hear much about it these days. No love? RL26 taking the spotlight? I like RL19 in the 25/06 and 280AI with lighter bullets. Maybe RL19 is yesterday's news?

my favorite powder in 243, 25-06, 260, 7-08, 300 win, 300 why, and 30 hart, I keep alot on hand

Reloder 19 is the only imported powder I use. Everything else is the locally made ADI powders. It has a good burning rate slightly slower than the 4350 powders. It goes very well in my .280 and 7x64. It seems to give a bit more velocity than the single base powders.

It's one of the powders I use in my 280 Rem that does well, but I do have better results with R26 and the 160s. In my 270s, I get better results with R22.

The most temperature sensitive powder I've ever seen is why I have no use for it. There are just better more temperature tolerant powders available that do the same thing IME....

It proved the best in my 7x57Ackley Improved. We don't have to worry about temps in Texas unless you hunt deep in the panhandle. powdr

I didn't know that. Thanks for the heads up.

v
either have I and I been useing it since it came out in 100 degree to freezing, never had a problem

Gemby have you actually chronographed and shot groups at "100 degree to freezing"?

Reloder 19 has worked very well for me in the 7x57 and 6.5x55.

RL19 had been a favorite of mine until I tried Ramshot Hunter now it’s my #1 favorite in 6-250, 257 Rob, 257 AI, & 30-06.

Prolly will be in 6.5x55 & 6.5-06 too...

It does everything 19 will do but better...

not chronographed, but point of impact dosent change, worked up load at around 35 to 40 degrees and use it in the summer for long range hog hunting with no difference in grouping

WOW that's a bit over the top IMO, I have used it for years without any problems, have seen many more temp sensitive powders than RL19.
Is more uniform from lot to lot than its big brothers RL22 & RL25

It's just experience over multiple cartridges. Use whatever you want, won't bother me...

For example, just in the 7-08, I've had two loads multiple years apart with different lots lose over 150 fps from 100 or so degrees down to 20's. A 139 Interlock load went from 2800+ to 2640 and impact was way off at 200 yards. Bringing out the Chrono with my camp in the truck to check speed was fun. When your crap is jacked the day before a big hunt, it's not cool. Just simply not worth taking the chance in this day in age...

H414, H335 and RL-15 are also not very good in the hot to cold department but 95% of folks will never know anyway. .

This is 100% correct

And the 7-08ai and 140’s did the same thing in similar conditions.

I’m used all I had for fire forms and. Ever looked back the temp resistance powders are just to good to fight the non.

Ran it in my 25-06's with loads developed in January/February. Along came summer and the actions locked up. Ran some over the chrony (magnetospeed) in January/February and they ran at 2950-2975. Ran ONE over it in June and it was a 3180. The roses sure enjoyed it though.

I must be lucky...

I never experience all sorts of stuff other campfire members seem to experience...

Then I don't zero a rifle in a low temp and then use it in a much higher temp or vice versa...

I zero it right around the time of year I will be carrying it afield...

And for someone who thinks RL 19 is the most insensitive temp powder they've used,
they evidently have never tried H 335 in anything...

If you don't shoot throughout the year and only hunt in your locale in similar conditions or don't shoot at long distances, you'll never notice, which is why I said 95% of folks never will, which you are a part of obviously...

Your H335 comment, which seems to be in response to my post - why don't you try reading my entire post again, which references H335 amongst others?

I myself shot long range and do it every day of the year and I use RL19 in both spring,summer fall and winter here in PA. I sure don't see problems like you have, must be where I live or where you live.
