| Comment | for a .50 Spotting gun pulled powder you could not ask for better performance. No unburned powdr grains in the bore. Outstanding performance at long range. ( tested to 300 meters shooting 2" groups,open sights from the prone by four shooters) This is a very cost effective powder that will work in most centerfire rifle calibers. |
