81g jsb 544 fps 53.2 fpe temple shot kill a coyote at 100 yards?

[militaryflip]

just installed my altoros regulator on my evanix max 9mm and and i adjusted the regulator up to 150 bar to get max 687 fps generating 84.9 fpe out the muzzle. i get about 14 shots from 679-687 es 8 av 682 sd 3 . 50 yards the pellets is going 615 fps generating 68 fpe and at 100 yards its going 544 fps 53.2 fpe. my groups are sub 2 inches at 100 yards every time and with 3 to 4 pellets hitting the same spot. set four very small apples out to 100 yards and i got 4 for 4. before i would have an average 3 to 4 inches groups and not so tight groups and its really hard to hit a regular size apple out to 100 yards. Is it worth to sacrifice the velocity and fpe for accuracy? i plan to take squirrel and up to a coyote with this gun.

Ballistics at 680 fps are going to be very loopy.  Your hunting success is going to depend on your ability to accurately range find. 

I suggest you look at the ChairGun program, free from Hawke Optics, input your data and look at the drop at various ranges and consider the effects of misjudging your range.  You may be surprised.

One more thing to consider when shooting long range at low velocity is the the muzzle report will reach the game before the pellet is halfway there.  Game may react before they get hit.

thanks for the input tom. i have this gun pretty much figured out and with the help of my range finder and aeon scope i know where to place the reticle at every yards 50 up to 100. i also practiced putting targets up to every ten yard increments until it get to 100 yards. im interested in the slayer .357 or 45 you got there look like the gun i been looking for.

I believe that precision is much more important than power; that said, more power is always better when going after 'yotes. As Tom said, your trajectory will be the deciding factor. I believe it can be done, but I would suggest shorter ranges under these circumstances.

I would also say that based on what I have seen, a Slayer would be my #1 choice for a dedicated 'yote gun (if you can justify it)

It sound like you've done your homework with the ranging.  I'd agree with plinker that 100 yards may be pushing the capability of your setup for yotes.

Not a coyote hunter or a long range shooter.....  So I apologize if this is a stupid question.

Since your pellet has an initial velocity of 680 FPS  (relatively slow) wouldn't there be a good possibility that the coyote would hear the shot and react (e.g. turn his head to look in the direction of the sound) before the pellet has a chance to travel 100 yards?  It seems like that would negate your ability to precisely place any particular shot.

That's a great point.  I saw a video from the UK where the guy was testing a sub 12 fpe 25 cal and hunting rats at night with a night vision setup.  His targets were under 25 yards and every rat he shot at reacted and dodged the pellet.

Yes it would most likely kill the Coyote if the shot was perfect, but with a 2" error margin as you mentioned at 100yds, it is very unlikely and I would not try it.

It depends on which way the 2" went.    I mean you could hit and break the shoulder, gut shot it, or skim it.  I would say though 2" is pretty accurate at 100 yards. A lot of powder burners barely shoot that accurately.  Of course they are going like mach one zillion when they hit it too!

Well this is just my 2 cents.
Hunting a coyote with a underpowered but regulated bigbore and taking a shot at it from 100 yards away is not a good idea.
My advice, if you absolutely must take a shot at a coyote at that distance, try to get the velocity up to the 800-900 fps range. If thats not an option, try to make it a 50-60 yard shot instead.

If the shot connects exactly where you need it to for a clean kill, then sure it can drop a dog. But at that velocity he's gonna bolt or at least move long before your lead reaches him.
And the last thing you want is a wounded yote or a yote thats aware its being shot at.

Yes.

I'll just try 60 yards that's should be challenging.

Just a point, the speed of sound is 1125 fps and sound doesn't slow down like a projectile.  At a constant 544 fps it will take .55 seconds for a projectile to travel 100 yards, (out your gun it will take less than that because your projectile slows to 544 fps at 100 yds.).  The sound will reach it in .27 seconds.  Granted a Yote can and will react to the report but it will have less than .28 seconds to move.  He is not moving that far in a 1/4 of a second.  According to studies done on humans our mean reaction time to sound stimulus is .26 seconds (couldn't find a number for Yotes).

A lot of critters have been killed through the years after hearing the report.

Just my 2 cents worth.

 valid point and it did cross my mind

its a lot of work i been tracking these coyote for a month now just waiting for the right moment
