superformance

I have some 30-30 cartridges I want to reload with Hornady Interlock 170gr. JFP. However, the only powder I can find at my local store is the Hornady/Hodgdon Superformance, and I can't find ANY load data for this powder and cartridge. Does anyone have any data for this, or this particular...

Hi Folks, I have been searching to no avail for any load data [published or personal] for loading .300 Weatherby Magnum with Superformance powder. I would think that this powder would work well due to the .300 WBY's large case volume. I am looking specifically for a 180g jacketed ballistic tip...

Is supeformance ammo for bolt guns only. Had the first Three rounds out of a new box blow primers all the way out, while leaving the case in the chamber .removed next bullet in line ,closed bolt & case ejected without a lot of force exerted

I found this interesting and possibly dangerous. http://www.hornady.com/ammunition/superformance-in-gas-operated-firearms
