No I haven't as yet, my max coal is 72 mm with that bullet and I have them seated at 70 mm. I still think it is more to do with the barrel when it heats up. After I was on the target and I adjusted the sights the next two were pretty close but the next three started to open things up a bit more. As it is it's ok for hunting within its range capabilities but as Mickey Duck said most 243s are tack drivers, it would be nice to get it shooting better.
