1coyoteslayer,
Hey, my state!!
Do you get any of those 75 V-max's to stay in at close range?
I got a good deal on the internet a while back and am loading 87 gr. speer TNT's ... have not drawed blood with them yet.
For my taste, the .25-06 is a long range stick and I liked the longer legs of the heavier slugs. (But then, I am in the east side sagebrush country)
Here, I went to the .25's for long range feral dog stoppage. The 75 Vmax stayed in big ones!!
But I don't have much coyote shots with them.
Just wondering
Best regards
Three 44s
I shot a coyote at 68 yards, he was on a steep downhill and i was above him so the shot hit the spine towards his lungs with no exit. It did look, upon impact, like it broke him in half lol. I zero the rounds at 250 so I can aim dead on to 300.
Thank you for the kind words!

These have almost identical case capacity and case design, hence my selection. Otherwise I'd choose the .243 or .25-06 for my personal cartridge preference.
What I'm looking at is with similar weight bullets (75 & 87gr), which cartridge performs the best. This means drop, windage, and damage to coyote on impact.
With all things being "equal", would a 87gr .25 do more damage than the 87gr .243?
I dont know how anybody got the .243 wsm to win anywhere. bcs and speed through jbm bcalc for comparison.
Keeping everything equal 243wsm and 25wsm the 25wsm is quicker but the 243 up on the BC a little, using 75 v max and 87 hornaday sp in both guns to keep it fair. there is not a lot in it about ten yards with the 75s roughly double that with the 87s but the 25 has it. Now in your post you say.. .243 or .25-06 for my personal cartridge preference. Now if you start to talk these two head to head things get a little more advantageous to the .2506. But the 25 wins, when you keep things as equal as you can.
243wsm/25wsm typical data obtained velocity from alliant and load data fastest for each weight of bullet in these chanberings. the 25 wins.

I have used the 243 and 25-06 for the majority of my coyote hunting since I started.
I've used most bullet weights and types from both, out to 600 yards with success.
In my opinion, the 243 is all you need to kill coyotes as far as most can hit them with about 80g on up.
With a 25-06, you can use most any 85g on up to kill dogs again as far as most can consistently kill them at.
The bad thing with the 25s is the lack of high BC (.500) or higher bullets. This really only comes into play around the 800+ yard mark.
All things said in my opinion, the 243 will kill dogs dead along ways off and do it with less recoil and powder, cost. You can use the 55s at 4000 for laser flat to 500, or shoot the 105 amax at 3000 to reach 1K. The 25 will zip a 75g vmax at 3800 and be just as flat or flatter to 500 as the 243/55g combo. Or you can use a 100-115g bullet at 3400-3200fps and have a waaaaaay better "dual purpose" coyote-deer getter. Thats where the 25 shines over the 243, deer size game. Coyotes only 243, coyotes-deer 25-06, I still use the 25 for dogs haha. I've always shot the 25-06 better and had more confidence in the rifle/load, and thats what it really comes down to. Coyotes are not big easy targets.
At the ranges your most likely going to be whopping coyotes, the 25-06 does hammer dogs more so then a 243 in my experience. The 25 simply has more power, plain and simple. I am not to worried if I make a bad shot on a dog with my 25-06 and 100g nbts at 3400fps or a 115g nbt at 3200fps out to 400-500 yards.

That's what i always look for when i plan a custom build is bullet first. Highpower has their place. Sniper-style matches theirs but i believe the long-range hunter has the most difficult problem in finding a bullet that gives the best balance for external as well as terminal ballistics to the longest range desirable in field conditions. That's why i've always liked the heavier for weight polymer tips as IMO they give the best long-range hunting "balance" overall.[For me] this means 22 cal. 75 and 80 A-Max, 243 87 V-Max, 105 A-Max, and 100 and 115 25 cal. Nosler B. Tips...but stay tuned they're supposed to have VLD Accubonds coming out soon that may change the game...slightly.

Nosler BTs:
6mm 95gr= .379 BC
25 cal 100gr: .393 BC
Nosler BTs (varmint):
6mm 80gr= .329 BC
25 Cal 85gr= .329 BC
Both the varmint bullets mentioned will make a nasty mess more times than not if you want the fur for selling.
Nosler partitions (what I would run in these chamberings for fur saving):
6mm 100gr= .384 BC
25 cal 100gr= .377 BC
I doubt you will be able to tell the difference between the two in the wind they are so close.
Both the 243 and the 25-06 are awesome. The 25-06 is just plain evil. My friend's Axis in 25-06 with 115gr NBTs will do some incredible things considering it's an entry grade rifle. my dad's old Marlin 25-06 with 75gr TNTs will make teeny groups at 200yds with not much thought put into it. I could only imagine what a custom 25-06 that is fined tuned to a good load would do.
Too mnay folks on too many predator hunting sights have sworn by their 25-06 rifles for excellent LR coyote kills. The problem with a 25-06 is the lack of match bullets which what was said on here before. And I too don't understand that.
Quote: Get a 260rem or a 6.5creedmore and stop waisting your time with turds.
To call two field proven, very easy reloading, extremely accurate, LR, hard hitting, deer/ coyote killing calibers "turds" is not too well thought out. The 260 Rem is sweet, but it's not the only piece of the pie that's sweet. Kind of like when a 308 die hard told me my 7/08 was a girl's rifle and sub par.

Gotta remember to that the 25-06 will run the 100g bullet some 300-400fps faster then the same 243/100g combo.
I can ring the 1K gong with my 25-06 and 100g NBTs at 3400 on a calm day no problem. The 115 NBT at 3200 is no different, and with a .453 BC, is as good as it will get for LR and the expansion you need to kill stuff from a quarterbore, the 115 vld is another valid option, but I'll take the NBT anyday with a similar BC over the VLD. I think 1K is about tops for the 115g nbt at 3200, and around 800 for the 100g nbt at 3400. You have to think about what your impact velocity is gonna be and what bullet is gonna be your best option. I dont like small target bullets at LR for varmints because they dont open up like polymer tips do and have the expansion and "pop" factor if a bad hit occurs.
The 243 with a 105 amax at 3000 with a .500 BC is basically the same as the 115 nbt at 3200 with a .453 BC out to 1K.
The 25-06 will get to 1K, just takes a bit more powder and blast, cost, etc to do so then the 243. So to those that say the 243 runs away from the 25-06 because the lack of high BC bullets are exaggerating a tad bit. 243 is just a little more efficient doing so.

This is what an 85grain NBT does at about 100 yards. I'm running these around 3550fps.
I'm not sure about the 243 just pick what you shoot well and go with it!

Ya know I just have a 243 and reload 85 grn speer. A 100 yds I put it on him at 200 I put it on him at 300 I put over his back a couple of inches and damned if I don't hit em and kill em. Just a good ole boy killing a few coyotes. My BC stands for better confidence. Just my two cents. I hope you all can hit them with whatever you shoot.

Go with a 6mm in a 1-8T barrel and a 105 A-Max and go have fun, if you want a bullet that will perform well.
The 105 Berger Hybrid will have abetter BC, but not sure on how it will do on yotes.

These have almost identical case capacity and case design, hence my selection. Otherwise I'd choose the .243 or .25-06 for my personal cartridge preference.
What I'm looking at is with similar weight bullets (75 & 87gr), which cartridge performs the best. This means drop, windage, and damage to coyote on impact.
With all things being "equal", would a 87gr .25 do more damage than the 87gr .243?

My choice would have been a 25 as i said, i have used .2506s for the past 30 years but not on coyotes. So zero expansion and fur saving have never been my priority. But on deer and TAHR in uk and New Zealand where i have family i have had good success with nozler accubond 110s the bc is 0.418 and they are a very accurate bullet in my tikka.
I think they could be worth a look, and they load at closer to 100grain speeds rather than 120 grain speeds if you understand what i mean.

This is the exact answer. Just shoot what you like and are good with.

Come on man, with about 100yds of thread and a needle, you could get premium price for that!!! LMAO, that is one dead Coyote.

I never haul those nasty things off. The buzzards won't even mess with em so why should I? I just see how big of a mess I can make of em.
That's the good side, the other side would probably get me kicked off of here.
