I have never played around with much powder before. I used black pwd for years out of my tc hawken and when i bought my white rifle they recommended pyrodex p and thats all I have ever shot. I bought a can of RS that wally world had on sale the other day to try. I thought about trying the shockey or some T7, but I havnt bought any yet. Dont know if it would be a waste of money to try or not. I have a optmia elite and a rem 700 ML to. I see on here where lots of fellers play around with different loads and components. I have always been if i find a load that works I just stick to it, but i have been thinking of playing around a bit.
