Yes, since the 2013/2014 hunting season that we have chosen to put in almost all our hunting references, the colors of a rescue operation, yellow, orange and red. These colors allow better viewing and easier collection in the field.
Of course, the cartridges vary considerably in the range of 10°C, the more if we consider that in our country, during the hunting season, we can be 35°C at the end of August to 0°C in January, a cartridge that is loaded in a condition to be fired is different from the cartridge that is loaded into another, one contains less powder than the other, respectively. This allows, if they are thrown from a reverse, in the first case the shooter will feel much more shot while in the second case, the cartridge will not have the desired speed and it will be too soft.
The ideal of conservation of cartridges is recommended on the packaging , ie, 21°C +/-1°C and 60 % humidity, however, and considering that only can this environment if forced/air-conditioned, we advise you to, naturally, assure temperatures should not fluctuate by more than 10°C nor should they get wet, so the best conservation is an empty and clean glacier.
Yes, all our references are set for a type of gunpowder, however, certain customers have already asked us the other that occasionally experienced and enjoyed more, these cases and approved by us the matched performance of this cartridge, also because we've already used it in time, we do it but identify this difference in the cartridge itself and at the packaging. What we mean is, if the cartridge has not identified the powder in himself, has gunpowder defined in its catalog, belonging to the characteristics that define for that shot/ reference.
