Load up 2.5" new hulls using the loading data as a "guideline" for your "low pressure smokeless" damascus loads........

Work up your own loads....not rocket science...just keep pressures low and find what works best in the gun you have.....

I load 2.5" in 12,16 and 20....and shoot them in old and new guns.......once you get the proper pet load that you like, you're in business..........

Good Luck....
