    Reloader 17 was the first powder I tried in the 6.5-284 but it is way too fast for bullets over 100 grs in the WSM. It will not fill to 75% with 130 gr bullets. I consider that dangerous. I would think that Reloader 17 would be outstanding in the Creedmore or 260 Remington with the mid range bullets.

    I have tried Superperformance in both the 6.5-284 and 6.5 WSM. I will say I like the powder in the 6mm Remington with 90 gr Accubonds. I have not found another niche for Superperformance where I was rewarded with either velocity or consistency. The local Cabela's salesman at the reloading counter swears he has gotten the amazing velocity listed on the container for Superperfomance in the 300 WSM with 150 gr bullets. I have tried several primers with it. I like 210Ms in the 6mm Rem.

    Reloader 17 is a great powder for 100 and 107 gr bullets in the 6.5WSM but it will not fill the case with heavier bullets. If I was interested in shooting the 107 Lapua at 3800 or more fps, R-17 would be great. VV N-550 was just as good but I did not wind out either powder with these bullets.

    I figured RL17 would be a bit fast in the WSM, thanks

    Re: New 6.5 Idea

    Well guys I finally found time to do some more velocity testing today. The weather was tolerable for a change so GoodGrouper and I hit the range for another session with the 6.5 BPX.

    WE started out with IMR 4831-- Temp in the mid 40's and a right to left breeze @ 2 mph

    47.5gr---2954 and 2958 fps --- ( 1 fouler )
    48gr-----2994 fps
    48.5gr---3028 fps
    49gr-----3061 fps

    The first two went into .120 then the third, fourth and fifth moved up and right about 1/4" but the next three went into a .101 . The last shot was starting to show a bit of pressure so I didn't shoot the rest of the string. This powder appears to be another good candidate!!

    Next up--- H 4831

    48.5gr---2895fps
    49gr-----2916 fps

    49.5gr---2929 fps
    50gr-----2949 fps
    50.5gr---2985 fps
    51gr-----3024 fps

    This was a disaster!! I shot the string with a loose Brake !! STUPID !! Old Age, LOL
    I don't think this would be the powder anyway, with the way others have shot, but it deserved a better chance than I gave it!!

    Next up --- RL19

    48gr-----2937 fps
    49gr-----2972 fps
    49.5gr---3013 fps
    50gr-----3037 fps
    50.5gr---3070 fps
    51gr-----3090 fps

    Rl 19 showed some decent shot clusters but not like some of the others accuracy wise but the velocity was amazing!! The last shot was showing a little pressure but not bad. 51gr was 100% filled.

    Next up --- RL22

    49gr----- 2997 fps
    49.5gr---3012 fps
    50gr----- 3059 fps
    50.5gr---3071 fps
    51gr----- 3101 fps

    Good old RL22!! First three shots went into .214 !! This load window will be hard to beat. Never found pressure but no matter since I couldn't get another tenth of a grain in there anyway.

    We learned today, that this bbl with this cartridge does not want to be shot at velocities exceeding 3060 or so. You can see it in the higher velocity groups.

    I thought that a couple of these powders would be too slow for my little case but I found out different today. I think shortened cases with less taper have a tendency to alter burn rates. I believe it's due to less powder kernels in contact with the brass case making a more efficient burn!!

    I'll see if I can get Steve to post some pictures of the groups tomorrow. Thanks for taking another look at our Thread. Hope you are enjoying our efforts. ---- RHB

    Roland....I will admit that I am really surprised at the velocity you are getting! I never thought it would happen even though , as you know, I am doing something similar. This is amazing and very good accuracy potential too. CONGRATULATIONS! I guess this may bode well for my new case......Rich

    Thanks Rich, I suspect your case is at least 10 grs larger in capacity and proportioned similarly so I'm betting it will be plenty fast!!! RHB
