Realoader 22 and Reloader 25

I'm currently working up a couple loads for two different 300WM's using RE-22. I know that alot of you have had great results using this powder with your 300WM. I did however run across another thread where a few of you said you would avoid these powders because the tend to be temp sensitive. I would really like to hear from both sides. If you love these powders or if you dont. I would also like to get some "real" numbers as far as what are the changes you delt with as the temp changed.

Thanks
Ryan

    Here is a real number on lot to lot variance.

    6.5-06AI had to drop over 4.5 whole grains to keep from blowing primers and breaking trigger sears from blowback. Three triggers in two days at a competition convinced me.

    Use RL22 at your own risk IMO. It is widely known that they are temp sensitive, but hey your gun.

    Suggest you buy MRP and MRP2 to replace RL22 and 25 but that is just me. Graf and Black Hills both sell MRP

    I've had great luck using RL22. Maybe it's because I usually work up my loads during the summer when it's around 80 degrees. Then when I hunt, it's cooler all the way to below zero. I think most have problems when it get hotter out than when they worked up their loads. All I know is that I'm not about to change now. BTW, my loads that I worked up during 80 degree weather worked well enough in sub zero temps to kill and elk at 623 yds. That's good enough for me.

    I love both of these powders---use them with very good results. Will say that maybe the lot to lot varaition is more of an issue than some other powders but that is why I buy "enough" of the same lot to last quite a while.

    BH,
    What's the story on MRP and MRP2? Are they the same as RL22 and RL25, but manufactured by a different outfit? Or simply similar burn rates as RL22 and RL25?

    AtownBcat,
    I think it's better now than what it used to be or at least I'm smarter about it now. I still use quiet a bit of it and as a matter of fact found an accurate load for my .300WinMag yesterday.
    I remember in July 2001 I worked up some 180gn loads for a .300WinMag Sendero that I owned using RL22 and Fed 215LRM's.
    I had changed 1lb containers but didn't reduce and work up. The first load (74.5) averaged 3198fps and accuracy went .888". The velocity of those three should have gotten my attention. The next three (75.5)were pushing the bullet past .300 Weatherby and RUM velocities (3253fps). Still I didn't stop and my buddy left the shooting area as I was determined to proceed with my loads. On the final three (76.5), the accuracy was .6" and velocity was 3300fps, the rifle kicked like the proverbial mule and sounded like a howitzer! I had to beat the bolt open each time with lineman pliers! Not one of my brightest moments.
    At that time in my life I don't think anyone had ever told me, nor had I read anywhere, that your velocity should not exceed the manuals velocities. I know better now and look for this in addition to various other pressure signs.
    I know this is a bit long winded but I had to share that. Other than that one time I have never had a problem with it and have had great accuracy with it. JohnnyK.

    PS. The load I used yesterday was 180gn Nosler Ballistic Tip, 75.5gn RL22, CCI BR2. Accuracy ran sub 1/2" and velocity averaged 3160fps. I tried this bullet/powder months ago with Rem 9.5M and WLRM primers and accuracy ran 1" or worse.

    this is whats hard about this sport...there can be input from polar ends of the spectrum and neither one is wrong. So EVERYTIME i go to a new can of powder i have to start the process all over again?!?
