Never have had any problems of any kind no matter what time of the year it is. I never do frequent areas where elk and deer congregate in the spring due to snow keeping them down so my shooting would never bother any animals.
I have had an officer or two stop to see what I was doing and why there was so much "stuff" but that has always led to a good discussion of guns and hunting. I think the only real things they are concerned about is safety, roads close to line of fire or things of that nature that are covered by state laws.
I suppose there could be the one sour apple out there that might want to make an issue of something but so far I haven't run into him yet.
