With a 6.01 barrel you'll need to use the best BBS you can find, and make sure you keep the barrel really clean.
If you're using the stock length barrel you'll be short of cylinder volume to push really heavy BBs, but something like Geoffs 0.36g should give good results. Make sure your ammo is clean as you load it, and keep the mags clean while you're skirmishing.
There's no substitute for trying a few different brands and weights to see what gives the best results.
