Magpro Powder

My 270 mk 5 shoots 75.5 grains very accurately with the 150 grain hornady sst.

I tried the 130 grain SST's, and they blew up going thru targets. Hornaday said I was going too fast for the design.

The 150 sst's do better than the 130's from what I have seen.

Got done trying Mag Pro in my 270 Wee. I was using 133 grain Shock Hammers and 67.5 gr. Charge. I was really surprised at the size group, 0.650 @ 100. Best group I have ever gotten out of my Wee. Bin loading hammer's lately and can say that they are the easiest and most accurate bullet i have ever loaded. They also shoot 1/2 inch groups in my Tika 270 win. Can't wait to shoot something and check the performance, cus i know they are accurate.
