Hey there nice work on your rifle,looks very cool , I want one in 577 LN , but I don,t have any skills

Say I think jeffeosso on AR has info on the 45/120 , it has to be a better idea !
Oh and on Hodgdon,s site under Cowboy Action theres loads , I uesed the 50-140 loads in 500 3 1/4 NE single shot I had made up , still has plently of power !
