I still have some left of a 10 oz. container I purchased a couple years ago.
I admit I am a cheapskate and that is probably the main reason I didn't shoot it more. The rifle I shot it out of was my disc elite. I was using the red jackets at the time and I spend a lot of time trying to get the breech area of that rifle spotless after shooting. I know the Lehigh breech plug solves that issue.
The powder was consistent, I had no problems with ignition and accuracy was great. As far as swabbing goes, I wait a while between shots when target shooting so I might as well be swabbing as standing there with my finger up my rear.
I sold my disc elite so all I have left are my Whites and my mk-85's and I prefer not to use it in them.
Overall, its a good powder for those who are set up to use it but it is just not for me.
