Definitive Guide to Hatsan Bullboss

Hatsan really put some thought into the ergonomics of the BullBoss. The stock is a great fit for just about any shooter, those with long arms may find the length of pull just a tad short but other than that it's spot on. The BullBoss also features an adjustable cheek riser to make sure that you get you eye lined up just right behind the scope. We mounted up our scope using medium height rings and found that just a few clicks up on the cheek pad got everything lined up perfectly. The stock is finished in a soft touch all-weather finish. It provides great durability in the field as well as an improved grip surface. We spent a warm afternoon on the range with the BullBoss and the non-slip soft touch finish really paid off as the day wore on and hands became sweaty. We also tested the BullBoss with gloves on and the generous trigger guard left no complaints for a gloved finger. The all-weather finish means the BullBoss is at home in any condition. As far as mounting optics, Hatsan uses a combination Weaver/Dovetail rail that lets you mount just about anything that you have. This is a great feature considering many airgunners already have a preferred scope and ring set up. Note that these aren?t standard weaver rails, but we have had no problem mounting on them. The BullBoss is also equipped with a lower accessory rail for mounting bipods or anything else that you would like. The Hatsan Bull Boss conveniently uses the same rotary magazines as the AT44 which means they are inexpensive as well as readily available. This, however, meant that the BullBoss is plagued by the same narrow magazine as the the AT44 making the use of longer pellets such as the standard Predator Polymag or the new JSB .22 cal Beasta no-go. However, we still love that the magazines are so quick and easy to load due to their open design and being that they are inexpensive; picking up a few extras for quick reloads is a must. The sidelever cocking mechanism of the BullBoss is silky smooth and its placement on the rifle makes it super easy to cycle while not having to come off the scope. We also found that left handed and right handed shooters both were able to cycle the gun easily and comfortably. We are big fans of Hatsan?s side lever actions and are happy that Hatsan chose the side lever for the BullBoss over their more standard bolt action that is found on the BT series airguns. The Hatsan BullBoss, just like every other Hatsan airgun uses the 2-Stage Quattro Trigger system. The Quattro Trigger is adjustable for both take up and pull length but out of the box they are excellent. Our test BullBoss pulled at about 1 lb 9 oz through the first stage and the second stage broke at about 4 lbs. The BullBoss, like all Hatsans, also features an auto safety located in front of the trigger that resets after each shot. The BullBoss is a powerful hunting air rifle, perfectly suitable for all types of small game. Available in .177, .22, and .25 calibers you should have no trouble fitting the BullBoss to your needs. For our tests we used a .25 caliber model and after chronograph testing we were thoroughly impressed. As far as accuracy is concerned the Hatsan BullBoss gets the job done. At 50 yards the BullBoss easily shot under 1.5 inch groups off the bipod and with some patience those group sizes could easily shrink. The BullBoss is perfectly capable of taking 50 yard shots on small game such as rats, squirrels, or similar game. The BullBoss features Hatsans Quiet Energy system that uses polymer baffles lined with cotton fabric to deaden the noise. It registered 81.4 dB on our sound meter. This is certainly not the quietest gun or even the quietest Hatsan that we have tested but we would still call it backyard safe. You can fill your BullBoss with a hand pump if you?d like, but we always recommend taking the plunge and making the one-time investment in a quality carbon fiber tank. Choose carbon fiber over more outdated and heavier aluminum or steel scuba tanks. Plus the carbon fiber tanks can be filled up to 4500 psi allowing more fills before needing to head down to your local scuba shop (or better yet fill at your local firehouse if you can sweet talk your way into hooking up to their compressors with the Air Venturi Firehouse adapters). The BullBoss uses a removable air cylinder that can be swapped out simply and without any tools. Hatsan BullBoss uses the same cylinder as the AT44 Long which means you can purchase extra hatsan air cylinders to carry out in the field if you plan on shooting more than the 30-40 shots one cylinder will typically give you. These extra cylinders are much more convenient to pack around than a 74 cubic ft carbon fiber tank. Extra magazines are a must for the Bull Boss, you?ll spend less time in the field loading and more time shooting, and they are much less expensive than competitors magazines. The BullBoss doesn?t have storage capacity for extra magazines like it?s older brother the Hatsan Gladius, but that?s what pockets are made for! We welcome your comments and questions.
