Re: Reloader 22

Oh boy. Here we go again. I suggest you do a search. It's been beat to death here. Most will tell you that it's very temp sensitive. I have used it in my 300 WM and never bothered to shoot over a chrono in different temps but it hit where it was supposed to at 625 yds when it was well below zero with a load that was developed around 65 degrees. I think if there will be a problem it will be from developing a load when it's cold and then shot in the middle of summer.
Now, I'm going to cook some popcorn and watch what happens.

Re: Reloader 22

Ditto on the " here we go again". My experience has been that is the load is developed in cool temps with anticipation of being used for hunting season, I can do some post season practice and when the temps are even colder, I have no problem. I have about six rifles that inhale this potion, and I have to be careful if I take them on a crop damage hunt in the summer. I have personally had difficult extraction on my 7stw, and my 300rum. SO, it seems that it does not like warmer temps after the load is set, but it shoots ok when it gets colder. My loads border max but are not at max. So when the temp increases, so does the pressure. Not so evident the other way. Hope this helps without confusion!!!! AIM SMALL, MISS SMALL ! 7STW

Re: Reloader 22

TnKnightSticks is asking an honest, & valid question, & hasn't posted on this site as often as some of us. This leads me to belive he may not frequent here as often. He has however been a member longer than a lot of folks, & deserves respect. Obviously we've all seen this question with this powder or that many times. But some folks may never have hered an answer, & what better place to ask than here?
I'm glad the members who posted are so polite. (so many newer members arent) Imo, both posts were right on the money too. (& somewhat comical haha) That says a lot a out the good people here on LRH.
Now, for a partial answer to your question O.P.....
Any load at or near max, with ANY powder, developed in cold temps (ie: winter) should not just be automatically trusted as safe in summer heat untill proven safe.
Work up to that winter load in the summer to be safe. Then there is no question. Use a chrono to tell you the difference in speed if there is one.
I have some RL-19 loads, right at max, developed in single digit temps that work just fine in Hells Canyon in August at 115*+.
My experience may differ from others. But in the end I really like Alliant powders, & would use them anyway even if they were temp sensitive. Id just keep better records so I could keep my drops simmilar with given loads. I also use Hodgden, & IMR, but they are a bit coarse. I typically use Alliant, RL-... vs Hodgden, or IMR, if my rifle likes RL. Personal preferance I guess.

Re: Reloader 22

An addition to my original quote, I absolutely love this powder. It has done things for me in the past 10 or 12 years that NO other powder has done for me. I could almost throw away all of the other slow burners that I have and use only RL22. it is predictable, and I have found lot to lot consistency to be excellent. It is magic in the big boomers and some of the smaller ones too. Now it is my turn to go make popcorn and see what happens. AIM SMALL, MISS SMALL 7STW

Re: Reloader 22

RL 22 is a great powder and accurate, but: I had a bad experience with it a few years ago in my 300WBY. As others have mentioned above, the problem was me working up a load in 55 degree temps and then trying to use it in the hot summer. The load produced quite a bit less than .5MOA accuracy at cooler temps. One summer day I took it up in the mountains on a 95 degree day to do some across canyon shooting. When I couldn't hit the broad side of a barn at 1K I brought it in and shot at 375 yards. To my surprise I was lucky to keep all shots within 4 MOA! That's when I learned about temperature sensitivity and how bad RL22 was in this regard. Switched to Hodgdon H1000 and have never looked back, better ES too.

Re: Reloader 22

So, if you did your load development in late spring, early summer ( hi 80's lo 90's) and then shot when it was in the fall (30's to 40's) what would happen. I too am a reloading noob, so I under stand if i get hammered. But im asking anyway.
