Well......... As far as I know, a 209 primer isn't a paint primer at all. It is an ignition source for the powder in a bullet. There are a few different types, 209 being one of the most common. They're most commonly used in shotgun shells, and black powder rifles.

Yes, you can if you are sure you need to.
Primer can sometimes be sticky if it does not dry well or is put on too thick. In most cases where there is low humidity a primer should not be sticky.
A 209 is a 209 regardless of what it is used for.
There are none produced that I know of, a 209 primer would be over kill in a revolver due to the small chamber and lower amounts of powder.
Among muzzle loaders, caplocks and flintlocks do not use 209 primers.
To install a 209 Remington primer kit, first ensure that your reloading press is compatible with the kit. Begin by removing the existing primer system from your press, if applicable. Then, follow the manufacturer's instructions to securely attach the 209 primer kit to the press, ensuring it is properly aligned and tightened. Finally, load the primers into the primer tray and test the mechanism to ensure smooth operation before reloading.
Federal 209A primers are hotter than Federal 209 primers and are hotter than Winchester or Remmington or CCI 209 primers. To duplicate your load when substituting Federal 209A primers in place of any other 209 primer, use 1 grain less powder for like performance.
Question can never be answered as currently written.
Depends on what caliber you are comparing it to.
Both would work, however a standard 209 should be plenty, and a magnum primer runs the risk of blow-back that could damage you and or the gun.
209. Double check with a gunsmith.
By 870 I assume you mean the Model 870 shotgun? If so, there would be no purpose for that type of conversion. Shotshell primers are of the 209 size. The 209 "conversion" is done with muzzle loaders. The idea is to replace the muzzle loader nipple (that holds the cap) with a conversion unit that uses the 209 shotshell primer to get more positive ignition of the black powder.
Depending on manufacturer and model of gun it would be a 209 shotgun primer for inline guns or a #11 for sidelock guns.
Yes, a Federal 209A shotshell primer can generally be used in place of a Federal 209 primer, as both are designed for similar applications in shotshell reloading. However, the 209A primer is hotter and may produce higher pressures, so it's important to consult your load data and adjust accordingly to ensure safe performance. Always follow safe reloading practices and check with reputable sources before making substitutions.
