6.5-284 Norma Load using imr-7828ssc

[bigmo101]

I have a question about a max load using imr-7828ssc.

I'm using 140 amax, COL is 3.056 and that puts it in the lands of the barrel.
Federal 210m primers 6.5-284 Norma.

I'm currently shooting 49.5 gr of IMR-7828ssc and getting great accuracy and about 2775 fps. The goal is 3000 fps if possible, the current load is just kind of slowl. I'm also going to try some Ramshot Magnum. Just have a lot of IMR-7828ssc.

Any info will be much appreciated

I am not aware of anyone who uses that powder for the 6.5 x 284. 3000fps is not a smart thing to do because pressure will get you before you get there. You can get close but be prepared to have a stuck bolt on a hot day.

Depends on who built your rifle however most folks I know who compete including myself use H4350 I get 2960fps.

Boss Hoss,

I do understand that there are powders better suited, but I have 8 lbs of the 7828ssc and would like for the powdwer to be used in the calibers I shoot. I also have a 28" barrel and I thought I saw somewhere that the max load was somewhere in the 53 gr range. I have no problems with my current load, but my wife shot three shots and I shot one shot... the stock was hotter from the sun than the barrel. Accuracy is absolutely awesome, three bullets almost touching at 300 yds. I was just hoping to speed things up a bit. As long is accuracy is good and I gain 125 fps... I'll be happy.

The fellow who built my rifle is a friend of mine by the name of Charlie Cano out of Scottsdale, AZ. The rifle is built on an actual pre 64 action. The way its set up right now, I'm confident out to almost 1000 yds. I just know the caliber can do more.

You should be able to do 51g easily and work up slowly from there. Another one recommended by John Barsness is H1000. Most of the F-class shooters use H4831 and 4350.

Thank you, that will work.

I'd think that in that cartridge with 7828ssc you would run out of capacity before getting into pressure problems. I loaded some in a 270 Win behind the Wildcat 169s and couldn't get enough in to make it worth it.

It would be well if you could get the extra velocity even if the group size increased to 1/2 MOA at your distance.
