how short is the barrel, Trail Boss Blue Dot just to mention 2 there are a number of powders that will achieve what you are looking for I shoot a 308 win at 1050Fps and a 35 Remington reduced with PC pistol bullets real slow 10" to 15" barrels
if you want change you have to put in your 2 cents, you can't just sit on the sidelines and whine
