Thanx, that's where the upper came from. They are allowed to own 50dtc but can not own 50bmg. Go figure. The only difference between the two is the over all length and the swell are shortened a 1/10th of an inch. Same bullet same primer, maybe a little less powder. But almost the very same thing. The guy that I bought it from did not want to sell any brass or bullets to even reload. So I am on a search for ammo. Thanx again!
