If it is any thing like regular 7828 I have used no. I use this in my 7mm rem exclusively , and shoot from as high as 95 deg down to 5 deg with no prob. I think the only deferience is the length of the grain.
The load data and speeds didn't match for me. I worked up until I got some pressure signs... then backed off a bit. Need to do more testing but I was getting 3000fps 200gr Accubond 24" Vanguard S2 300wby... 83grs 7828ssc
