    I have had trouble finding powder too. I have a savage 110 ba and I am using 81 grs of IMR 7828 ssc with a 300grs Nosler accubond. The grouping is a tad bit better with the 300. At first the groupings were so so. I seated my bullets at max with a 3" grouping at 100 yards, then I seated them .010 deeper for a 2 grouping. So I went .010 deeper again and it shot a 5 shot grouping 1 ragged hole at 100 yards. You could have covered all 5 shots with a quarter. I believe finding the right bullet seating is more important than worrying about powder you will never find.

    You will love it!! I load it in my 338 RUM with the 265 LRX bullet. Accurate as the day is long. I would not hesitate to use this powder at all. Is it 7828 ssc or plain 7828?

    ssc mean super short cut. It flows better in the powder dispencer, but it has the same burn rate as regular 7828. All load data is the same.

    -Ya Man- I'm sure ^^ doublezranch ^^ knows what ssc stands for. He was just simply asking what powder the -op- had found.
