When stunning with a captive bolt pistol, it is essential that you select the correct grade of cartridge for the animal's size. If the grain used is too low then a shorter tonic phase is more likely which, in turn, increases the risk of an animal regaining consciousness before sticking. This compromises both the animal's welfare and the operator's safety; the livestock is not insensitive at the point of despatch and there is a significantly increased threat of injury to the sticker from involuntary kicking. If the cartridge is too powerful there are also numerous drawbacks: - Heavier cartridges cost more; using the wrong one wastes money. - Excessive wear on the firing chamber increases maintenance requirements; increasing spare parts costs and delivering a less effective stun as performance tails off. - In either of the above cases, a processor is risking their 2009/1099/EC compliance by not following manufacturer’s recommendations for the most effective use of their equipment. - Cutting Edge supply all 3 grades of Matador cartridges (black, red and blue). They are sold by the thousand and then divided into boxes of 500 cartridges.
