Home Forums Hunting & Shooting Ask The Gunwriters What Does It Take - to Hunt Medium/Large Game at 600 Yards?

Not specifically, but have seen testing where they don't reach full BC potential from a 1:10 twist Bbl.



Also keeps the 165's on the table as well, although so far it looks like the added velocity at the expense of a few points of BC is a good trade for the 150's.


600 yards - would be 150 gr./2100 fps/1500 ft-lbs.

Put in the right place, that should be adequate.


As a custom Bbl. that doesn't cost extra for it, w/ an application dedicated to 140 gr. TSX on up... 1:8 seems right.




GR

Why it's been completely unexplored up 'till now.

Just have a candidate project rifle that might be nice to have rigged that way.

The re-Bbl. cost is reasonable for the project.

It's the other goodies that may put it in the realm of ridiculous.

Have an old 3-9x40 Leupold that should work ok, but no "dialing" w/ that.




GR

DC is a placebo.

AK

That's kinda what this is.

Even good field marksmanship starts to fall apart on an 8" target past ~ 350 yards... and can be problematic past 400.

600 yards - requires a < 1 MOA rifle, and a < 0.5 MOA shooter.


Accommodations - are probably necessary.

But won't really know for sure 'till the rifle is built and run at range.


Most of my 400+ shooting has been with service rifles w/ aperture sights.

The addition of a scope alone - may be enough.




GR

Only under ~ 400 yards.

... where 99.98% of hunting takes place.

A .400 BC controlled expansion .270/150 gr. will put almost any NA game in the freezer at 350 yds. if one has even basic marksmanship skills.

You are probably looking at Bryan Litz's numbers, which basically work but also don't take into account plastic-tipped bullets. The guy who devised the present twist-rate formula, the late Don Miller, eventually discovered that plastic tips don't count very much in overall bullet length, because of their light weight. When using plastic-tips, a more accurate formula is JBM Ballistics', which includes an input for tip length. It indicates that stability is more than enough to maximize BC at typical mule deer/elk temps and altitudes.

I also wonder why you would consider the same 150 ABLR load adequate to a lesser range than elk than deer. Are you one of those who believes in a certain minimum amount of foot-pounds at impact for various animals?

Came across this a while back the first time I started lookin' at this project:




Never hunted elk.

But they are bigger than mule deer and Minnesota white tails.

So, w/ relative SD and bullet construction, will plug 1500 ft-lbs for elk and 1250 ft-lbs for big deer and hogs, along w/ associate impact velocities.




GR

GR,

Sorry, but the more you post, the more I'm certain your knowledge of big game hunting is more theoretical than real.

What is theoretical, is hunting past 400 yards.

The formulas used to determine bullet selection and impact velocity, on game inside that range, have proven themselves over a lifetime of hunting.

Your opinion - is yours.

... and sounds kinda small at that.




GR

It’s almost a shame Burns isn’t around.

Does he use a lead-sled to shoot 100 yards, too?

Like a club member?




GR

Not exactly.


But his ego would give yours a run for the money.

You're the offended one.

What's your problem w/ facts and the truth?




GR

We must determine our definition of “long distance”! Here are my personal requirements….. An accurate rifle, using a fairly high BC bullet upwards of .30 caliber, that will give adequate expansion at the pre-determined distance limit involved, lots of trigger time with said rifle, and carefully choosing good atmospheric conditions! When you’ve satisfied all those parameters……having, as in my case, over 2000 ft/pounds of remaining energy at my personal limit of 600 yards is desirable! memtb

You have missed my point entirely.

And I will be the first to admit that Burns has forgotten more about long range shooting than I will ever know.

This thread - is an exploratory about a hunting rifle for > 400 yards... outside me hunting envelope.

Whatever your point was... it wasn't relevant.




GR

Wind-calls would be tricky.

Numbers say ~ 3.5 MOA at 600 yds. for a 10 mph full deflection wind.

Not a good setup for a game shot.




GR

#crutch

For > 350 yards on game?

Try it and let us know.

8"... not 80".




GR

Here's to ya.

2000 ft-lbs. at 600 yards, even for a heavy rifle, bumps me out of precision shooting.

1500 ft-lbs. at 600 yards, with a 9.5 lb rifle, is about it, and not all day long, either.

But the .270 Win. can do that, if one is careful.
