I just stumbled across this post. Interesting topic since most people don't ever talk about blacktail hunting. I have lived in the NW most my life and have been hunting blacktails for 29 years and am still no expert. I feel they are one of the most underrated game animals for their elusiveness and intelligence, and one of the most prized trophy's the NW has to offer.
I think there are many key's to success to put together a successful hunt. First developing areas with high deer population by scouting pre season. I use spring/fall bear season to find areas that have a lot of deer as they are usually out in the open more when less people are in the woods.
Taylor your day of hunting based on the weather, if it is a mild day with no or light rain probably focus on clear cuts, as there probably isn't enough sound cover to hunt the timber. On heavy rain or stormy days focus on the timber and still hunt. I like to find timber patches that have at least 1 clear cut if not timber that is sandwiched between cuts.
If you are going to hunt clear cuts don't be afraid to walk down into them. Often times deer are at the bottom where you cant see them from the landing or ridge top. I have taken some nice bucks by starting just in the timber line and hunting out into the cut, since the deer are almost always going to try and make for the timber, they will often run by you on the opposing side of the canyon offering a nice opportunity at a shot.
Always play the wind. If the wind is at your back your going to lose. Period.
If you haven't read Scott Haugen's book " Trophy Blacktail, the science of the hunt" get it, read it, then read it again. Its the best single source I have found for strategies of hunting and behavior patterns of blacktail deer. You can probably buy it at Bi-Mart.
Don't rule out stand hunting blacktail either. I have a piece of property that the landowner lets me keep a ladder stand on, and I use it sometimes as a close in after work hunting area. I have taken 2 good bucks from it and my daughter harvested her first buck from it. I will use deer blocks and whole corn with a trail cam.
I have never hunted southern Oregon, I hunt the coast range. From what I have seen southern Oregon bucks get a lot bigger racks than the brush country bucks I hunt. You should have some great opportunity to bag a monster if you play your cards right. Hope this helps.
