Sometimes the "buck fawns" get killed before they figure things out haha!
I've sold 2 rifles the past couple weeks and dropped them off at USPS myself, shipped to an FFL. In general I believe only long guns can be shipped and only through USPS by unlicensed folks sending to an FFL or themselves.
I can attest to the accuracy of the above mentioned 444s. This gun traveled across the US to my door, sighted in, and killed a deer within an hour of it's first hunt. She's deadly.
Like always when you shoot an animal, I didn't even think of the recoil. When sighting it in, it had enough punch to make you remember it. But shooting the deer, that was a distant memory. I tried to slow down and focus on squeezing the shot. It worked like a charm.
I wasn't using the FTX, I found a couple boxes of Superperformance soft point 265s. Those shot accurately and so I stuck with those. Ask the old gal on the receiving end of it if it was effective :D
