Its made by Ultimate Firearms. www.ultimatefirearms.com.
Mine is built on a Howe 1500 action, Lothar barrel 1/26 twist. It will shoot consistant MOA groups, Trying alot of different loads to see which will be best for distant. Its a toss up between the 285 Barnes Spit Fires and the T/C Shock waves(Hornady SST's with different sabot). 200 grains of Pyrodex pellets. They make it with a Rem 40x action and a aluminum bedding block. So far very impressed with the gun. Have close to 300 rounds through it already and its only 2 months old.
