H&R Handi-Rifle
Depends on the sniper and the rifle. Add about 15-20 inches to the barrel length, same as any other rifle. The Remington 700 action used to be very common and probably still is. Barrel lengths are about the same as any varmit rifle, from 20-26 inches roughly. Contrary to popular belief, a longer barrel will not make your rifle more accurate, and people who shoot for a living should be aware of this fact. That is not to say that if you go and buy a Remington 700 from walmart and stick a powerful scope on it that you have a sniper rifle (actually, by military designation and modern rifles, you might). Usually special care is taken and the common varmit components are changed, the barrel is one upgrade that is helpful for making a rifle more accurate. Other things, like bedding the action and floating the barrel are almost requirements for a competition rifle, and a non-reflective coating on the objective lens is probably an essential for a sniper. In short, to answer your question though, 35-45 inches. The .50BMGs are probably the same length but I don't know too much about them. Same as a varmit rifle.
Gunsmith or maker.

It is a heavy barreled varmit rifle
The one issue with 5.56 in a handi rifle is the harder primers. You will almost absolutely have to install a heavier hammer spring. I have some Malaysian 5.56 and it often won't fire in the handi. I have heard the same about the Rossi single shots. As far as your concerns about pressures, the Handi handles all sorts of calibers on the same frame and barrel blank. Many of those push 65k or so. I don't worry about any difference in 223/556.
Well- sort of. Single shot top break rifles, such as the H&R Handi Rifle or the Thompson Center can change barrels, and can shoot several different cartridges- but not from one barrel.
