I figured it was... that is all that I shoot T7 loose powder and I really like it. There is a new powder on the market BH-209 - it will probably be very hard to find locally. but it does not present the 'crud ring' problem

If you continue to shoot T7 make yourself some windex patches and run one of them after each shot and you will have no problem with the build up of the 'crud ring' + you can make up another set of them that are wetter and actually pre-clean the bore.

Here is how I make mine - just make sure these patches - the patches you might use at the range are moist - not wet...



When hunting I just toss 4 or 5 of them into a zip lock and drop them in my pocket. If you are hunting in freezing weather just switch to car windshield washer cleaner.
