It is a used gun, but looks to be in good shape, no dings or bad spots that I can find. It is chambered in .270 WSM and has a 28" octagonal barrel. My Wheeler trigger pull gauge says it has a 2 3/4 pound pull. It came with Conetrol Custum rings and bases. The barrel has some carbon fouling in it, but no sign of copper so far. I haven't bore-scoped it yet.

I don't have a scope or any ammo for it yet. - But I have a new Nikon Prostaff 3-9x40 that I keep around the shop, and put that on it so that I could play around with it a little. Some 130 grain Federal ammo has been ordered, but I won't see that for 4-5 business days.
My son has volunteered to act as my gun-bearer if I get a chance to hunt, so the 8.8 lb. un-scoped weight doesn't seem too bad. Any way you look at it though, it's a heavy firearm. It handles well though, and feels good on the shoulder.
Looking around on the internet, I could not find a reference to manufacture date by serial number. - You can find that data for the old original Winchesters, but I've had no luck looking for dates on the Miroku-made guns.
Anyway, I've wanted one of these for years, and I'm looking forward to shooting it. - I've already found recipes for low-recoil practice reloads, shooting 110 grain bullets at 2000 fps that are alleged to be accurate. With full-power hunting loads it should kick less than a 7mm Remington mag, especially in this heavy rifle. With the 28" barrel, it should perform well and maybe not be so muzzle-blasty.
It took me over a year to come up with it, but finally I have something good for hunting in west Texas. - Now all I have to do is get my son to romance some rancher's daughter so I'll have a few thousand acres to hunt on!
