Not early but the model 7 predator came in 223. They are camo. 1/9 if not mistaken.
The first ones made were 1-12 ROT, later versions were 1-9. I have one that's a 1-12 and it is very accurate with bullets in the 40-55 grain range. I had a later one in 1-9 that I sold to a member on here. It also was a good shooter, and I really couldn't tell any difference in the two rates of twist with the bullets I was shooting.
I have a 223 Model 7 stainless that's a 1-9 ROT and I've shot bullet weights up to 64 grains, and it's a good shooter as well. Personally, the ROT's in a 223 don't really bother me, as I don't shoot bullets heavier than 64 grains in my bolt rifles.
