While browsing the Ruger website I noticed that the Ruger M77 Mark II Frontier rifle has been discontinued.
The Frontier rifle featured a forward scout-style scope mount and a very short 16.5″ barrel. Sixteen inches in barrel length may be considered normal for rimfire or intermediate cartridges, but the Frontier was chambered in full power cartridge such as .308 Winchester and .300 Winchester Short Magnum.
The short barrel would certainty have had quite an impact on performance. These cartridges are usually fired in 20+ inches of barrel length, and this may have contributed to its demise.
The advantage of a short barrel is less weight and easier maneuverability in a tight space, such as shooting varmints from a vehicle, or when traversing heavy bush.
I was really hoping this concept would take off and am saddened that it did not catch on. Once you have fired, or owned, a short barrel (SBR) rifle, everything over 14″ seems much too long!
Does anyone own one of these rifles? I would really like to get my hands on the ballistic data for the cartridges the rifle fired. Ruger have not responded to my requests.
