I read in prior posts that a "H & R Blackpowder Handi-Rifle" was shot & tested. I did a search engine on this rifle, but could only find a "H & R Huntsman" on their website. Is this the same rifle that was tested? Also... the Huntsman offers 209 ignition, but the manufacturer does not state whether 150 grain loads are acceptable. Anybody here with some "know-how" on this subject???
