Many shooters prefer to use padded soft cases for their guns. These weigh less, take up less room in vehicles, and store more easily. Unfortunately most soft rifle cases on the market are too short (or not tall enough) to handle scoped rifles with 29″ or longer barrels, particularly if a muzzle brake or extended front site hanger is attached. You can find long soft cases designed for shotguns or long-barreled black powder rifles, but these typically do not have enough clearance (top to bottom) to handle bulky target scopes. Where can you find a quality soft case for a scoped F-Class or Palma rifle with 30″ or longer barrel, making the rifle at least 50-51″ in overall length? Here are some suggestions.

55″ Bald Eagle Match Rifle Case
A good combination of features and value is the 55″-long Bald Eagle soft case from Bullets.com. This case was designed for match competitors with long-barreled rifles (with barrels from 29″ to 32″). This case fits both scoped and iron-sight rifles, and has quality zippers and heavy-duty padding. Large, zippered storage compartments hold log books, chamber flags, and other gear. Available in two popular colors, red and black, this case measures 55″ long, 13″ tall on back end and 6″ tall on front end. It is currently on sale for $57.95. Bullets.com also sells 60″ soft cases, and 50″ soft cases to fit rifles with both longer and shorter OALs.

52″ Creedmoor Sports Soft Case
At the request of many High Power shooters, Creedmoor Sports has created a high-grade 52″x10″ softcase. That’s tall and long enough to fit a Tubb 2000, or AR-based spacegun with long barrel. The Creedmoor case is one quality offering, with nice 1″ thick close-cell foam padding plus tough Cordura nylon on the outside and nylon pack cloth on the inside. Both materials are urethane-coated for water proofing. Another nice feature are the integral backpack straps (see photo left). These free your hands to carry rests, spotting scopes or other gear.

The Creedmoor 52″x10″ case comes in Forest Green ($66.95, N152A), and Royal Blue ($76.95, N152C). Creedmoor also offers a similar, slightly smaller 48″x12″ case for Service Rifles in Green or Blue.

52″ Midsouth Gun Case
For those on a tight budget, Midsouth Shooters Supply offers an Extreme 52″ padded gun case for just $23.00 (item #208-BD240-52). This thickly-padded case is high enough in the center to fit most scoped rifles — even with big Nightforce scopes. Made by Bulldog Cases, the all-black Extreme 52″ case features a soft faux-fur inner lining, an external accessory pocket, and a removable shoulder strap.
