It's still early for people to have resources for other primary's. But getting a 280 to 295-300 is easy if you have been banking 295+ blues. 300 LL Gives you a really good level to start playing around with it. Then one or 2 raids later infuse it up with the shitty hand cannon you are bound to get. Hung jury is the top gun because it's easy, but the raid scout, treads upon stars, and last extremity, Are all very good base weapons. Get a good roll and use that.
