someone recently posted a thread asking about this. I wasn't able to figure out attaching photos until recently.
This is a 1943 Remington barrel. They were made with only 2 grooves and lands as an economy measure, but they turned out to shoot just fine. Made as they were to fill a need until there were enough M1s, I suspect a fair number of these were shot very little. And I think the 2-groove design may not wear as quickly, and definitley cleans easier. Look down the bore: all you see are 2 very broad grooves, maybe 1/4" wide.
Any how, the groups are below. In the photo with the 168 gr match bullets, you can see part of another very good but bigger group on the lower left. That group was the same load, but made using standard full length dies, versus the show-off group loaded with bushing-type hand neck dies. All brass received the full treatment: sprted by weight, neck turned, primer pocket uniformed, flash hole reamed.
