In part 1, here, I described the Winchester 670 and a little bit of its history along with some of the unique features I found:

  • Completely unbedded action.
  • Original ‘Tip Off’ scope ring mounts.
  • A 3X9 X 40 once inch ‘tee vee’ screen scope.
  • Factory iron sights.
  • 19 inch carbine barrel.
  • Exceptional trigger for an ‘economy’ rifle.

This past weekend, on 26 October 2018, I took it to my KDR (known distance range) to check out it’s accuracy potential on a bench.  I took two different brands of ammo with me that had some common characteristics (besides being .30-06).  Both had a 165gr Sierra HPBT Game King mounted on very nicely polished brass.  Brands:  Omega Ammo & Fiocchi; and both loaded to, or close to, match specs.  Temps were in the mid 40’s and it was raining most of the time I was there.  So, good weather to check how it’d perform during a hunt.

Generally, the Omega had better (tighter) groups and the Fiocchi was a bit hotter, as it’s point of impact with the same aiming point was about 2 inches higher than the Omega.

I was pretty pleased with both brands, but the Omega edged out the Fiocchi.  You can find out more about Omega ammo, here, if you wish.

The first target, below, was a fresh one once I got the rifle on paper at 25 yards.  Basically, I took for shots.  The first is the flyer.  It was the first shot for accuracy.  When I checked it out in the spotting scope I made a sight correction and fired the other 3 consecutively, with only the time it takes to leisurely bolt the rifle and repeat the firing process.  The other 3 shots are pretty much in one hole at 25 yards, so the accuracy potential is there.


The next image is of the iron sight check out at 25 AFTER the scope was sighted in.  I did this so that when I went to 100 yards, the scope would have been taken off its original zero, and would be prone, if the mounts/rings weren’t solid, of having a different point of impact.

To continue, the upper holes outside of the ‘X’ indicate what I did to bring it center and down on the ‘X’.  The very tight group in the ‘X’ is how it fired at 25 yards with semi-quickly bolted rounds, simulating rapid fire on say, a bear, or something, coming at the shooter.

Now, remembering that both these targets were shot at 25 yards, I was still pretty happy.  I don’t have the eyesight anymore to shoot iron accurately beyond that, so that’s where it’ll stay for anytime I need to flip the scope out of the way.  And, yes, the scope was tipped off to the left, and re-secured before I went to 100 yards.

Stealing my own thunder, I was amazed at how it kept its zero at 100 after being tipped over.  Very solid mounts, and great performance from a scope that’s about as old as the rifle.

The first target is two groups of 3.  You might find the points of impact as interesting as I did.  The second target with blue lines indicating the group was the first 3 rounds; the second target with the yellow lines was the second string of 3 rounds.

The red dot is about 1 1/4 inches or so in diameter, so all in all, I find this rifle to be a keeper.  One thing I always look for to confirm inherent accuracy potential is the ‘triangle’ shaped group.  It means the barrel harmonics are consistent with the cone of fire; the closer the group, the more consistent the harmonics.  For an economy rifle, this one has superb harmonics, especially when taking into account the lack of bedding and stock features.


All in all, I fired 40 rounds of both Omega and Fiocchi through this neat little rifle.  Its performance, with no custom work on it at all, convinced me that back in the ’60’s, even an economy rifle could perform to match levels.

This one will be making a trip this November…
