One reason why I want to stay with the 270 is to prove some people wrong but that is just me.

To who?

I said this in another post that the 270 wasn't a LR target rifle due to lack of bullets.

I don't think anyone disagrees. With good bullets it is a match for the 30-06, which is clearly not the best, but a proven capable long range target round.

And by the way the lead time in barrels is probably because you want a .277 barrel. I bet you could get a 6.5mm barrel quicker ;)
 
emcon5, I think alot of problems happen when posters start comparing calibers like the 30-06 to the 270.

As to the lead time on rifle barrels. I waited just as long for the Rock 270 5r barrel as I did the Bartlein 5r I put on my 30-06. I have no problems waiting for a barrel always got something to shoot and when the gunsmith completes rifle with the Rock 270 barrel he has a Kreiger 1/8.5 twist SS barrel in 6.5 cal # 4 contour for my next project.
 
If you haven't bought the barrel, give strong consideration to the 6.5-06, throated for 140s. Does everything a 25-06 and a 270 will and much better bullets. In 24", I'm getting 2935 with 140s, 3070 with 129s, and 3150 with 120s. Then, there are the 100gr Noslers.........
 
The .270 isnt the best choice for your long range needs but why not if your going to build it custom. With the right load worked up for it getting softball groups at 800 should be achievable. Off the top of my head Im not sure whether you should try the 110gr bullets or 130s, the 150s will drop to much. The bullet I would try would be a Sierra for sure. I think that with some time and practice you prove these guys calling you crazy wrong.
 
Why would I choose a .277" bullet with a BC that maxes out at about 0.530, when I could shoot a 6.5-06 or .280 Remington (aka 7mm-06) from the same parent case with a BC that exceeds 0.61?

Here is an article from 6br on 7mm what's interesting they have a drop chart on some of the popular calibers

http://www.6mmbr.com/7mm284.html


If they made a target bullet for the 270 same BC as the hunting Berger 150gr VLD and ran it in a 270Wby 3250fps maybe more be interesting to see what happen. But we all know that's not going to happen.

Exactly what I was talking about when I said the .270 falls off the table out that far. These are the rounds I have the most experience with.

.270 Win 150 grain Nosler Partition
MV: 2830 fps
ME: 2667 ft-lbs
Velocity @ 500 yards: 1928 fps
Energy @ 500 yards: 1238 ft-lbs
Wind drift @ 500 yards: 19.7"
200 yard zero drop @ 500 yards: -44.1"

.270 Win 130 grain Nosler Partition
MV: 3060 fps
ME: 2703 ft-lbs
Velocity @ 500 yards: 2012 fps
Energy @ 500 yards: 1168 ft-lbs
Wind drift @ 500 yards: 20.2"
200 yard zero drop @ 500 yards: -38.8"

And what I meant by having to "lob them in" past 300yrds.
I'm not saying 1100yrd shots ain't doable. Just not what it was meant for.
 
Ok well a Partition is useless when shooting 1100 yards in my mind. First lets run the numbers with a 110 gr bullet and then try it with some handloaded sierras and 1100 becomes much more plausible

What do you mean "fall off the table"? At 500 yards pretty much every round "falls off the table". Once you get past MPBR you have to either adjust your scope or practice hold over. As long as you've worked out your adjustments and can judge the wind properly then you can work most rifles at long range.

Look at it this way, if you shoot an 8" diameter target for MPBR here are some numbers you can chew on.

6.5X284 142 grain SMK @ 3000 fps MPBR 341 yards.
.270 Win 140 grain NAB @ 2900 fps MPBR 324 yards.
.30-378 Wby Mag 200 grain NAB @ 3150 fps MPBR 356 yards.
.338 Lapua 300 grain SMK @ 2670 fps MPBR 310 yards.
.50 BMG 750 grain A-Max @ 2940 fps MPBR 346 yards.

So pretty much after 310-350 yards you are "lobbing" all these rounds because they fall out side the target diameter. Once you get past MPBR you are having to adjust for trajectory anyway. Just some cartridges are going to need more adjustment than others. The .270 really doesn't start to loose out until you get past 500 yards.

You have a strange way of disagreeing with me by telling me what I say is true.

We're not talking about any round but a .270.

So if I have a 200yrd zero with a 130 gr bullet it will drop -38" @ 500yrds and a 150 gr will drop -44" @ 500yrds?

So in case anyone is having trouble with the math, that is 3-4 feet @ 500yrds.

So what's it gonna do @ 1100yrds or in other words, 1/2 a mile?

So in order to hit a man sized target that far I have to "hold over" 6 feet? That is sounding like a Howitzer shot...or "lobbing". Like artillery.

The original poster was talking about target shooting. Unless his target is a semi trailer, I don't think the odds are good with a .270 at that distance to be cosidered a good precise shot every time.

I've shot a heck of a lot of 1000 yard matches with a 308. The 270 shoots flatter then the 308, so how is it that a 308 is good for 1000 yards and the 270 isn't.

I agree that there are more match bullets for the 308, but, there are a few out there for the 270, Berger makes some dern nice long range match bullets for in .277.

There is no such thing as a flat shooting bullet. We have this nasty old thing out there called gravity. You learn what gravity does to your bullet and adjust those little knobs on your scope/sights.

Go to a BPCR Creedmor match. Those 45-70 have a trajectory that requires notifying FAA. If they can do it, why not a 270.

The same thing for wind. I don't care what bullet you shoot, the wind is going to move it. Just learn to judge wind. If a 10 MPH full value wind pushes your bullet X inches at 1000 yards, then again, twist those little knobs into the wind.

If the OP wants a long range 270, by all means build one, I think it can be done.
 
Well, first of all, if you are shooting 1100 yards, you don't zero at 200. You zero at 1100 yards.

You get a 20 MOA Tapered base and a 30mm tube scope. You don't "hold over" you spin the knobs on the scope.

With a 1100 Yard Zero, a .277 150 gr Berger VLD at 2900 FPS climbs from the muzzle to around 600 yards, where it's apogee is ~11 feet high.

For comparison, a A .308 210gr Berger VLD @ 2500 FPS climbs from the muzzle to around 600 yards, where it's apogee is ~14 feet high.

(and the 140 gr 6.5 tops out just under 10 feet).

And as I mentioned way back in post 22, drop does not matter for a LR target gun. All that matters is wind.


Isn't this horse beaten enough? Yeah, you can do long range shooting with a .270. There are better options out there, but there are also worse. Hell, I shot a match last month with 7.62X54R out to 800 yards, and .270 runs lazy circles around that.

I never backed any of your statements up. I asked you to explain what you meant by "falling off the table"?

You need to spend a little time running the numbers because you still don't have a clue as to bullet drop. JBM Ballistics has a nice little trajectory calculator. If you run the numbers you will find that the .50 BMG will have like 20 feet of drop at 1100 yards and the .270 Win will drop a little over 32 feet. I doubt you'll be able to push a convetional projectile to 1100 yards with only 6 feet of drop.

So what's it gonna do @ 1100yrds or in other words, 1/2 a mile

Wrong again, there are 1760 yards in 1 mile and 880 yards is 1/2 mile.
 
Guess I don't posses the proper communication skills to properly defend my opinion.

1000yrds=0.568181818 mile

1100yrds=0.625 mile

Sorry. You're right .568 is over half a mile. If I knew I was debating math and science teachers I would have taylored my response and not used generalizations.

Yea I know about bullet drop and gravity. Thanks. Although I admit I don't keep a ballistics table taped up in the garage.

"lobbing in"- Adjusting your bore alignment (angle) to reach long distances. You are no longer aiming parallel with the ground.

"falling off the table"- Shooting parallel with the ground and Mr. gravity takes over.

Your are NEVER aiming parallel to the ground. If you were, you would never hit anything except the ground.

Everything "falls off the table" if you do that. Gravity starts effecting trajectory the millisecond the bullet clears the crown.

The 6.5-284, if you aim "level to the ground" (zero range of zero, and sight height to 0") drops 2.1" to 100 yards, 8.6" at 200 and 20" at 300.

Even a .220 Swift at 4000FPS drops over an inch to 100.
 
HUH?

:confused:

WOW! I must be doing something special. I usually hit what I'm aiming at and not the ground.

I can see we are getting nowhere. I will bid you good day gentlemen.

110gr bullets or 130s, the 150s will drop to much.

You do understand "ballistic coefficient", don't you? Or .....maybe not ...... even Hornady's 110 V-Max boat tailed bullets only have a BC of .370 ...... we are talking here of shooting 1/2 mile+ ......

"Muzzle velocities are a depreciating asset. Ballistic Coefficients, like diamonds, are forever."

You might be able to launch a 110 gr V-max @3300 f/sec, but by 500 yards it has slowed to 2080, and dropped 40 inches from a 100 yard zero ..... while a 150 gr SST launched @ 2900 will have about the same speed, and dropped slightly more, it will lose it's speed much slower than the shorter bullet..... and the flight path is not even 1/2 way done..... I don't have table to 1000 yards handy, but I'll bet the difference in drop, and more importantly, drift, are huge past 600.
