    Tested three clients guns in my last range session and had some interesting results.

    First gun was a 25 wssm and I tried my control lot of IMR 4064 that I've had for about 5 years and found a great load. Then I tested it again with a brand new lot in Hodgdon bottle. The original load was with the control lot was x velocity and had a standard deviation of 5. The new lot was tested half grain below, equal, and half grain above to re-tune the sweet spot. The gun liked the exact same charge, had the exact same standard deviation, and the average velocity was 6 fps slower than the control. Very good in other words.

    Then I try a control lot of IMR 4350 that is about 10 years old in a 270 wsm and it yeilds x velocity with an sd of 4. Then the customers lot is tried which is an 8 pound jug and also is in the newer bottles. It gives two feet per second more speed than the control, has an sd of 5 and shoots same size group. Very nice!

    Then I try another customers gun in another 270 wsm and it favored RL19. My control lot was about 4 years old and gave x velocity with a standard deviation of 7. The new 5lb jug of current manufacture gives 48 fps more velo and prefers 1 grain less powder to regain the same velos and has an sd of 9. In other words, if getting a new lot of IMR, seems they are doing just fine since Hodgdon took them over. Alliant still has lot to lot consistency problems they require different loads if switching lots. It still shoots good, but dang, these guys need to do something that Hodgdon/IMR have already figured out! I'm about ready to dig up some serious quantities of Norma powder to get the Alliant accuracy without the Alliant problems!

    I have not been happy with RL for the past couple of years now. There are just better powders out there for the reasons you stated. I've been phasing out all my RL powder and going to other brands such as Ramshot and VN along with IMR/Hog

    I have been using IMR 4064 in my 17 Rem since about 1973. It does not give me the speed that some other powders might, but the factory stock rifle seemed to have liked it way back when and still shoots the same size groups with it- mostly MOC (minute of crow).

    I burned more IMR than any other powder. It seems like they're not as temperature sensitive as some other brand. It's my go to powder when I'm developing load for a new rifle. I hope Hodgdon will keep them that way. RJ

    Hey GG,

    If you should happen to find some Noma MRP, let us know where you get it. I have one can left that I am saving only for loading my .300Wby, as it seems to be the best powder for that rifle.
    Used to be sold thru Graf &amp; Sons.
    I have heard that Black Hills was supposed to sell Norma powder, but have not seen it available yet.

    Anybody else no anything about where to obtain Norma Powder?

    Regards,
    Vic

    Powder Valley just started carrying Norma powders. You may want to try them. They list MRP as being in stock and have about the best prices for powder in general that I've found.

    I forgot to mention that everything was loaded on the spot same day. A direct comparison in other words.

    358STA,

    Thanks so much for the tip.

    I just checked the VAllEY POWDER web site:http://www.powdervalleyinc.com/

    and sure enough they do have Norma MRP @ $19.00/lb.

    Now I can start shooting that rifle again.

    I have heard the RL22 is supposed to be the same exact powder as MRP except that the quality standards are higher with the MRP. This was told to me by a Norma rep. But regardless, I seem to get much better accuracey with the MRP then the RL22.

    Thanks again guys,
    Vic

    Vic,

    Black Hills Shooters Supply has Norma but you will need to get your FFL dealer to order them as they sell to dealers only. 10 lb minimum but free shipping.

    With my FFL, I arranged for a shipment to a buddy of mine in San Diego.

    Hope this helps.
