Had her out today with these for the first time. A few observations:
1. I had two "fail to feeds". They would chamber 9/10th's of the way but I couldn't close the bolt. There's nothing obviously physically wrong with them though that I can see?
2. These shoot higher by about 3" and to the right a tad compared to the S&B 250gr ones I zeroed with. They are consistent.
3. They leave a dark ring of what looks like carbon around the part of the shell that the bullet seats into. Is this normal? It is different from the S&B shells which leave a tad but nowhere near as much as these.
Most of the shells chambered beautifully; easier than the S&B ones. I had a few that it was tough to get the bolt down with but ejected perfectly. I had no difficult extractions with these AT ALL, which is different from the S&B's where I have the odd one that I have to give the bolt a bit of a whack at the top of its stroke to eject. Nothing serious, just a bit of sticking. Back when I first got the rifle I had very difficult extractions with it all the time and it ended up needing the chamber polished. Apparently a very common problem with the 110BA.
I have the Lee Breech Lock single station press. It has a much smaller diameter ram and mine is sloppy at best. Do what Woodsoup says and go with the Classic if you choose a Lee.
