You gotten a little farther in your quest . Is the rifle synthetic, laminate, or wood stock? If synthetic or laminate stock then your fine as it is. Is your rifle bought new or used? If its new, I personally wouldn't fool around with it as Browning already made the barrel free floating. If used then there are things you can do to the barrel/stock fitting. Other than that there's the trigger, and some other stuff like new barrel, new stock, etc. but then that's customizing. Like most of us, our guns will out shoot us anyday.

I'm not a gunsmith. Farfrom it. In my infrequent trips to the gun range - perfer to shoot in the field because of extreme cheapness, I met a guy whojust bought a new rifle, synthetic stock, and shot groupsthat looked like abunny at 100yards. He wasliterally shooting the same hole. The guy on the other side of me, was a custom gun maker shooting a new 5K gun for a client but was shooting 1" groups. A$600 rifle vs. a 5k custom rifle? It was the person shooting the rifle.So, your question should be "what can make me be a better shooter?"
