(A couple questions for the Winchester experts at end). I picked up the rifle in title today. Someone was selling some rifles from their uncles estate. Ad said pristine condition. They said they had the rifle in their possession for 12 years and never fired it. The uncle moved to Chicago many years ago and left his guns in Idaho. Based on the condition of the rifle, everything seems to add up. No wear except you can tell the bolt has been cycled some, but not much. I brought the gun home and cleaned it up. Ran some patches through it. Zero copper found in the barrel. I only had to run 4 patches through it before they came out clean. Just a little gun powder residue. Very smooth bore. I had one of these in 7mm STW a few years ago. It came with the BOSS. I never fired it. It seemed really cool at first but the barrel on the BOSS rifles are super short. About 23” plus the tunable BOSS system/brake. Luckily, I flipped it for a profit on gunbroker. Here’s some of what I know (think I know) about the rifles. Build for 2-3 years in the late 90’s Made in: 7mm, 300 Win, 7mm STW Pre 64 action design. “Classic” part Made in the custom shop Douglas barrels My Questions for the Winchester Experts: 1) Does adding a muzzle brake affect value? (I’m not a rifle collector but maybe this is the start of a new hobby) 2) I’m wanting 20 MOA base(s). Single piece or two piece. What options? Update: That wasn't too hard. I found what I needed. 3) There's a spacer in the mag box. Is there an “extended” mag box option, without the spacer? Currently mag box is about 3.39”. If I remember correctly, my 7mm STW had a larger mag box. I believe Winchester has/had a XL action. Just wondering for this offering, if they maybe used the same action for the three camberings (keep costs down). Update: I ordered the longer, Winchester Mag Box. About $30 delivered, I'm going to try running it with the original spring and follower first. 4) Should I even shoot it? Maybe I should just hide it away for a while? Update: I'm just going to shoot it. 5) skim bed or bed lug area? Update: I'm going to skim bed the rifle (DIY). I've bedded multiple rifles, in the recoil lug area. I think I'm going to step up my game a little bit and do a complete action bedding. I'll just keep the post going with my experiences. I'v had a heck of a time finding good, usable, info on these rifles. Maybe not that interesting but someone might come across one of these.
