Hmmmm,there can only be one answer to this question.fast follow up shots.hmmm,maybe two answers.fast auquisition and shots on multiple targets,gaaads,three now.more ammo in the fire arms,maybe a forth,most can not afford a quality semi or full auto firearm and choose to ditzz the autos...
I own a couple bolt rifles(and I think I can operate the bolt pretty fast),But when I really get after those filthy coyotes,I take two semi autos to the set with me.one rifle in .223 and a shotgun in 12 ga.both hold more then 5 rounds.and both can empty there high cap mags faster then most folks can get two shots off from a bolt gun.and this can be done accuratly.
It makes me wonder why an experienced coyote hunter would ask such a question.But I now know.
and I think it makes a difference were you are located and where you call,what yer preferance might be.around my parts.I have had upwards of 20 filthy coyotes running at me all at once from all points on the compass.
I have had herds of the critters racing at me neck and neck through the desert trying to get there 1st.Then there is the fact that not only coyotes answer the call.but bears,bob cats and mt lions.heck, I have had deer come charging in.so I want to shoot fast some times, and accurately.and have a lot of lead going out to stop a charge if I have to.
I saw one of you use an M-1 carbine..I have two of them..one is a highly gone over one.synthetic stocked, 11 degree crown,wolf springs through out.polished and honed moving parts.trigger crisp at 3 lbs.I have loaded bucoo ammo for it.my favorite is the norma 93gr soft lead nose with a buch of accurate powder under them.the bullets are silver in color.and very accurate at 50 yards.don't have a scope on them so I shoot open sights at 50yards at a 2"orange square.I took the rifle hunting one time.It was a cold winter day.was sleeting and raining.I went out to the city dump.and went a bout 500 yards from the land fill and with the wind in my face I started callin on top of a mesquite dune.I had a 30 round mag in the rifle.well several coyotes started coming in I could see one in front of me and one to my left and one coming from my right.the 1st one there was the one coming from the front.I fired at less then 20 yards and could see fur fly.the coyote turn to retreat.two more rounds fur flew then the one on my left broad side let two ripp at it then three at the one on my right.those bullets acted like icepicks on the coyotes.found blood and tracked for a while.I guess if they were hit in the spine are the brain pan they would have been mine.but they were not.I am sure two of the coyotes recieved fatal hits.but ran off to die else where.I have never taken it hunting again.just to competion matches were we shoot two guns(rifle and pistol) at close quarter ranges.I have read a lot about using # 2 shot for coyotes..interesting.I am sure it will do the job at close range.as that was my favorite in the jungles for shooting turkeys.but it was 2 3/4s loads.and was devestating on them.but I can tell you from a lot of experiance that #4 buck in 3" mag is a coyote killing load.I have shot many coyotes at 85 plus yards on the run with it and they have crumbled.
but then I have done the same with BBs.I don't believe two's have that power at that range.I might be wrong.
