I feel it has to be just improved some. Winchester, .45, .39, and the rest.
It is getting very difficult to go house to house for hours on end coast to coast looking for specific ammo., All military bases, all airfields all high rises, and all areas.
Winchester rounds are almost impossible to find, and also .45 i will not mention the mosin rounds, or the vss rounds they are becoming almost impossible on rust buckets, and smokers to locate. If your very lucky you get the ammo can.

I get you guys are trying to make it so hardcore, however the pistols are spawning 30 in houses in balota but we have no ammo whatsoever.
Even 9mm is not all the easy to find.

I believe very strongly it needs to be given a slight boost to locate. Could be 2 or 3 or even 4 boxes found in a home on the shelve. Farmer did not use these but has some stock piled. Its common in today's world to find a gun owner with ammo in the cupboard.
