I have moulds for the REALs. A .45 in 250 grains and a .50 in 320 grains. In fact, that .50 mould is the only one I have for that caliber. Results with a given bullet are going to (or make that "can") vary widely from rifle to rifle. I think you might want to stretch your distances a little before taking a bigger leap. How they hold up out at 100 yards will really tell if they are stablizing properly and weathering the storm. Some rifles do very well with the REALs and I'm hoping my little G2 will like those 250 grainers. Very easy and inexpensive to make and a couple of hours will get you a season's worth of bullets.
