Did you check the "Crown"? Try the Q-tip trick, take a Q-tip and insert it in the barrel and pull it out slowly and see if any strands of cotton come off the q-tip. If it does you have a burr which could be causing your problem.
Another trick I have tried is to take some paper shims and put them in the cut for the recoil lug, tighten the rear action screw first and then the front, this will lift the barrel out of the barrel channel a bit and free float it. Fire a group or two and see if it makes a difference, If it does you have some barrel contact some where.

I have a bone stock Weatherby Vanguard S2 which is the same rifle as the Howa 1500, 2nd generation like you have there. Mine is chambered in .308 and shoots less than an inch at 100 yards with every ammo I have tried, including wolf and military surplus.

Provided nothing is mechanically wrong with the rifle, I am guessing the erectors in your scope are no good. The reticle is bouncing around inside the tube of the scope with every shot and giving you that poor accuracy.

Try all the tips and tricks suggested here and then put a different scope on it. Also be aware that good scopes are not cheap. Unless you get something used or stolen, a good scope that you can rely on for good accuracy is going to cost at least $150. I like the Weaver brand of scope myself. Check out Natchez shooters supply, Natchezss.com for good deals on weaver and other scopes.

If it were mine, I would place another scope of known reliability on the rifle and shoot it again. If the accuracy improved, I would place a better grade of glass on the rifle.

Redfield used to make good scopes right here in the USA, and I have a few of them, but they were shut down by the EPA back in the nineties IIRC, and had to declare BK. The newer Redfield scopes are a division of Leupold, and just like the lower end Leupold's, are made in China or the Philippines. Not saying that they can't make decent scopes, but the construction and QC are not up to scratch with more expensive glass. Even the vaunted Vortex, which is also made in China, has problems, and the only thing that saves them is their lightning fast customer service and replacement policy.

Another thing that I would check is the distance off of the lands for your particular bullet. Hornady makes a good gauge to check this. It used to be Stony Point, but Hornady bought them awhile back. I have a Winchester M70 in 6.5x55, and it wouldn't shoot for beans. I glass bedded the stock, and that helped a little, but going from 6" groups to 4" groups isn't a great improvement. I bought one of these gauges, and found that the distance from the lands to the ogive on the Hornady 129 gr IL that I was using was almost a tenth of an inch. Yikes! I seated the 129 gr IL out to just off the lands and accuracy settled into 1.5" consistently.

Good luck figuring it out. Kinks with new rifles/cartridges is very frustrating, especially when they have reputations for accuracy, but it is what makes this hobby interesting.
