be conservative
I had one and it never shot but I have built them and got good varmint results but I would never chamber the caliber for anything but hunting. I have however spun light bullets apart with a fast twist and warm load. I have a 223wssm now and have not had the time to test it I will be shooting 90 grain Berger bullets and have lengthened the throat so they can sit way out past the doughnut. looks funny but I hope it works well. if you would like to discuss more on this then feel free to PM me and I will send you my # or we can talk on here as far as a good load goes I went with heavy to beat the wind better and keep the velocity up since I could not go to full loads with many of the frangible bullets and do not have any advice in that area.
