WELCOME!!!
The thing to remember is consistency, its very important. Free floating the barrel is one thing that works for many owners, but nor all. Bedding the forend is not done much, but it too can help. Forend fit to the frame is another place adjusting can change and enhance the barrels accuracy. Shooting with out the forarm is one way to see where your problems lie. Proper shooting position and trigger control are another two places accuracy can be enhanced. I am just touching on these points, as the FAQ's will have links and in-depth information to explain them. Give them a thourough read and come back and ask any questions you still are stumbling over.
Good luck,
