- Description
- Contractor Question: We know from your description that the cartridge bodies are made of brass. What are the projectile bodies made of? Metals, plastics or composites? Are the surfaces of the projectile bare, painted or coated? -Government Answer: The projectile is made of steel. The surface of the projectile where the sealant is applied is bare. Contractor Question: Are there drawings that indicate how a sealant is to be applied and any requirements that material must have? -Government Answer: This notice is a market survey; therefore, we are just looking for general information on contractor capabilities at this time. If a solicitation is issued a drawing will be provided at that time. Contractor Question: What cure speed requirements do you have for the sealant material? Are they minutes or hours? -Government Answer: The sealant shall cure in hours. Contractor Question: How is the sealant material applied? -Government Answer: The sealant is applied to the projectile crimp groove by spinning the projectile against a sponge that contains the sealant. Contractor Question: How does the projectile fit into the cartridge body? Is it threaded or a compression/press type fit? -Government Answer: The projectile fits into the cartridge case by compression/press. After the sealant is applied 360 degrees to the projectile crimp groove, the projectile is inserted into the cartridge case. Then the cartridge case is crimped 360 degrees around the projectile crimp groove. Contractor Question: What is the tolerance between where the projectile fits into the cartridge body (i.e. what is the gap fill requirement)? -Government Answer: This notice is a market survey; therefore, we are just looking for general information on contractor capabilities at this time. If a solicitation is issued a drawing will be provided at that time which will contain the tolerance requirement. Contractor Question: Is the propellant component and the primer of the 20mm round corrosive? Are either reactive in any way? -Government Answer: The propellant and primer are not corrosive and reactive. The propellant contains mostly nitrocellulose and nitroglycerin. The primer contains mostly barium nitrate and lead styphnate.
