Like you I was new to LR shooting 5 months ago and did hours of research online. I have both a Barrett MRAD and used custom RWS Rem 700r 308 for shorter distances (800 or less yards) and for CHEAPER practice. What I concluded was you need the right cleaning equipment-appropriately sized bore guide, coated single piece cleaning rod, alloy jags (instead of brass), nylon brushes. I use Bore Tech Eliminator cleaner, Kano Kranoil, and Bore Tech grease (for the bolt).
After placing the rifle in a gun vise, I run a patch or 2 soaked with the Eliminator down the barrel and let it sit for a minute or two. Follow that with dry patches until carbon and copper show up only minimally on patches. Then run a patch through with a few drops of Kranoil followed by a chamber mop (20 gauge shotgun mop) to clear the chamber and lightly grease the bolt areas of wear. Rarely need to use the nylon brush and would avoid harshly brushing the crown area.
Don't clean again until accuracy starts to fade or if I need to store the weapon for a long period. May lube the bolt from time to time in the interim. I feel more barrels damaged from incorrect or over cleaning than shooting. Also avoid long strings of shooting without allowing the barrel to cool.
Remember just my opinion and you need to find what works for you. Good shooting. I hope this helps !!!
