Seeing how it was designed in part by LRBT, I don't think anyone else will for a very long time, if at all. It doesn't bother me though since I got one hole groups from my .30-378 using bullets by them.
Those were the 220 grain J40's. IU will use tha J36 for hunting this season though. I may be in Northern Minnesota (my cabin is anyway) but there are several power cuts by me which give some 400 yard shots.
