Long Range load for Coyotes/AR-15

[zr600]

Earlier they were comparing 22cal 55g bullets and 6mm 55g bullets.

Earlier as in 14 years ago.

according to hornady load data 147 gr from a 260 rem gets around 2650 fps. A 150 gr from a 308 Win gets a out 2750-2800 fps roughly same size case same bullet weight much diff. bore size.
The man has a point albeit a small one

 

[Shawn Carverelli]

When I look at my .260 and it's ballistics and compare it to the .308 which is the parent case I don't see it.

Maybe if you're running a very light for caliber bullet in the .308>?

even if MV in a bigger bore is slightly more the BC of the narrower bullet negates any advantage in under 300 yards...making it a mute point

 

[Shawn Carverelli]

Same case with a larger bore will push the same size bullet little faster generally.

I stand corrected...doesn't make sense to me but I checked it out. Dang, that's the 3rd time in as many years I've benn wrong

It only holds true though with heavy for caliber bullets in the smaller hole and heavy for caliber bullets in the larger bore.

Guess which wins in the energy equation?

true enough

Are you saying your .223 case necked UP to 6mm shoots 55gr bullets faster than a .223 55 gr bullet in basically the same case?
To me, that theory is emperically unsound. The 6mm 55 gr bullet is ballistically inferior to the same weight/ shape .223 bullet.
Something doesn't add.
Unless you meant. 223- 6mm

that 6x45 is a real ball buster for otes my favs are 55 and 65 6mm

You guys shooting varmints with AR's amaze me. I shot the M-16 in '67 and if we hit a target the size of a half sheet of plywood we would get an expert badge.

You were shooting in the Army for an Expert Badge?
Semper Fi!
Big difference since "67". My Coyote & PD AR shoots down to 1/4" MOA with .224 - 65 gr SGK

Thanks for you service!
I thought that only the USMC got worn out M-16 rifles like all our other gear.

6mm arc ar, 200y, 3 shot group. 87gr Vmax handload.

I don't know why anyone would shoot anything but an ar for varmints. I also shot a bunch of m16 rifles with burned out barrels in my years in the army, but the platform is capable of amazing accuracy.

An A R 's accuracy depends on a lot of things the same as a bolt-action rifles does . They like all other things have evolved over the years and improvements have been made , a lot depends on who puts them together on the civilian side of it as to how well they shoot groups . As for my coyote hunting I still like a good bolt action rifle mostly because that is what I grew up with . A223 running 55 grain Sierra boat tail hollow points for normal calling and a 6.5x284 running 120 grain Nosler ballistic tips for things at a little more distance . You guys might try an M14 there were a few of them still in use in the brown water taxi service till around 4/29/1975 . I don't really care what branch you were in you are still in the original 1 percent club good and bad in all of them, people are people some of them are upstanding and some not so much .
