The preceeding is my #1V in .22-250. Those are 3 consecutive five shot groups at 100 yards
.
Quick words on the #1:
1. the #1B and #1V seem to be the most consistently accurate. Something to do with those medium weight, straight tapered barrels. .243's and 6mm always seem to shoot very well in them.
2. The ones with bands on the barrels are often more tempremental, but also can shoot well.
3. If you find a used one, check to see if anyone has been whittling on the foreend. If so, expect a challenge getting it to shoot well.
4. Before whittling on gun, or trying to re-engineer Bill & Len's masterpiece, try handloading and different benchrest techniques, first. Like any gun with a pressure bedded barrel, they are sensitive to how they are held on the bench.
5. I too have heard the late models shoot well. I for one want a .45-70.
The above experience is based on owning four, and having loaded for three others. They are special rifles. Of my four, only the .375 H&H won't stay under an inch at 100 yards, and I think a better scope and a better shooter would solve that problem.
I still remember one that got away, a #1B .220 Swift that I saw in San Angelo, TX 12 or so years ago. Full figured buttstock and foreend, simply gorgeous, even better than the one above. If that owner happens to be reading this, I will give your Swift a good home, and make it dance
