hodgdon superperformance powder

Has anybody used this powder yet? I was interested in using it in my 22-250 and my 6x284.

Re: hodgdon superperformance powder

I bought 8lbs. of it not too long ago. I worked up some loads with 55g Accu-tips. I loaded only 2 rounds per charge weight except for my start load.

Savage 12bvss 26" CM 12 tw PRVI case,55g Accu-tip 2.410" oal.
40.0=3427 41.5=3623 43.4=3851
40.0=3367 41.5=3613 43.4=3875
40.0=3418 42.0=3642 44.0=3975
40.0=3427 42.0=3663 44.0=3968
40.0=3418 42.6=3724 44.4=4065
40.6=3467 42.6=3755 44.4=4052
40.6=3454 43.1=3798
41.0=3527 43.1=3756
41.0=3454

The 44.0 loads just started to show a tiny bit of flow around the firing pin,they didn't look flattened out yet just raised ever so slightly around the pin mark. the 44.4g loads were a little worse yet but didn't look too bad. At 44.4g the case was filled to about .060" below the mouth,not much room left at all and really compressed.

Only data I found was for a 60g V-Max so I just backed off the max load for that and worked it back up. I loaded up some 50g dogtowns too but have not shot them yet,also got some 69g match coming to try as well. I also loaded up some .308 with 155 A-maxes but need to go higher on charge weight to get velocity up more still had room in case for more powder and wasn't getting close to having pressure signs yet. Odds are it will be compressed pretty good to get the velocity up.

As Always start low and work it up.

Re: hodgdon superperformance powder

I was of the impression from a lot of the Hornady Superformance Ammo hype that they had a "special blend" for each cartridge family e.g. small rifle, large rifle, magnum...

But, it looks like just one powder to select from and little or no load data published.

I'd be curious to see comparisons of H4831sc and Superformance for the 6.5x284.

I hate to waste what's left of my current my barrel life. So, I think I'll stick with H4831sc for now.

Let us know how it turns out.

Thanks
Richard

Shane G:

What cartridge were you loading? Any update? I am interested in shooting 77 and 80 gr VLDs in my .224 wildcat which is close to a .22/250 in volume but has a small rifle primer. Is Superperformance going to be the powder. It sure is in my 6mm Remington with 87 V-Max and 90 gr ABs.

Re: hodgdon superperformance powder

I use it in my 22-250 AI and love it getting close to 3800 fps and .3moa with a 60gn berger, A little spread in velocity but have shot it on paper out to 600 and holds .3 moa so very pleased, getting a 22-243 build and am going to try, a buddy of mine uese it in his 243 AI with same results, very underated powder in my opinon and being a sperical it meters fantastic

Re: hodgdon superperformance powder

Thanks for your prompt response. I like velocity so 3800 with a 60 gr from a 22/250 AI (I gave mine away) seems impressive. Do you coat your bullets?

What primers have you tried? What have you learned about primers with Superperformance? Does the ES and SD lessen with maximum loads or with less? How about seating the bullets? Does pressure spike with bullets into the lands as opposed to seating with a jump to the lands?

Re: hodgdon superperformance powder

I have about 8000 WLR primers so i don't switch primers i make them work, and that might help some for sure, I also keep my bullet into the case because it is my coyote rifle so haven't pushed the limits to much found and accurate load and stuck with it
