Home Forums Hunting & Shooting Long Range Hunting Loooonng Range 'Chuck' - cartridge choices? Help please!

I am really surprised nobody has mentioned the 6x47 Lapua. I am in the process of building a Long Range gun myself and after a lot of research, I decided on the 6x47 Lapua. It's a great cartridge and definitely worth looking into.

Tom-theres a lot of ways to skin a cat no doubt. But, a 14 twsit for a long range big 6 is one of the last things I'd do....?

I have two favorites for such work. It is really hard to beat a tight twist .22-250 or the AI version. I like them both a lot wtih the 75 grain AMAX. No finer bullet for that kind of work to 800 yards and change. I have shot some unbelievable groups with them at 1,000 yards. They still expand perfectly at that range as the previous pictures show.

My second choice is the .25-284 with either a 75 grain Vmax at over 3,700 fps or the 100 grain ballistic tip at a shade under 3,500. Both simply get there and tare stuff up on shots under a grand. For shots over a grand, then VLD's are in line, but for the ranges your are playing at, thes just work. It takes some good equipment and a good spotter for shots over 800 yards. The .243 isn't bad by any means and I used it for years, but I like the previous two much better. Flinch

TOM, nothing like driving around with the gear box stuck in reverse. I think your buddy hasn't shot much over 300 yards. I think he is simply stuck on speed and bragging about such things. A 60 grain bullet is like putting a 4 popper motor in an F350 truck. It might sound cool and run pretty fast, but when it comes to getting truck stuff done (true long range), it sucks!The guy that built it and is driving it might think it is cool, but nobody else does. I can't for the life of me see any logic in what your "gunny" friend is trying to accomplish. Flinch

Here u go--the "6mm Long Dasher"--

Thanks for the link, SSCoyote! Like I said, I am amazed more people aren't talking about this great little round.

I hate to sound like a rig stuck in first gear but... If the chuck hunter is not recoil or noise shy, a 300 Win or Wby or Ultra, shooting a 200 grain bullet, is just as flat as a 6 mm anything to 400 yards and flatter beyond, and is about 10 times as immune to wind drift. While I admit to missing as many as I hit beyond 600 yards, I still would use that combination if the big money was on the shooting bench.

Wayne

The 300 may be as flat shooting, but doesn't it seem like a bit overkill on a chuck? Also, such a set-up would use a lot more powder and therefore would be more expensive to shoot, so what's the point?

As for bucking the wind, most experts would agree that a bullets BC has as much to do with it's ability to do so as it's weight. Stating that a bullet is "10 times as immune to wind drift" just because it is bigger and heavier is simply not true. Sorry.

T O M hit the nail on the head, for a speedy 6mm, the 6mmx284 is the ticket. To keep things simple, the 243 AI would be the way to go.

Well, well. Ballistic coefficient does have a lot to do with wind drift, which I not only admit, but preach. That 200 grain 30 caliber has a B.C of .50 to .56, so + 1 in that category. In addition, the greater mass of the bullet resists deflection (wind drift) better than lighter bullets. To carry it further, a 50 caliber 750 grain spire point starting at about 3000 fps is flatter and less affected by wind than lesser bullets. As far as expense is concerned, if you can't afford to do it, use the time you would spend "chuckin'" and get a job as a box boy at Wally World so you can make ends meet.

Wayne

So you are saying bullets of the same B.C. but differing weight, differ in wind deflection given same starting velocities?

I"m reading it to say, same BC in a 224 bullet and a 338 bullet, at same velocity, net same wind drift. Which is the way I understand it.
BC relates to aerodynamic shape, and the shaplier they are the faster they get down range. Wind drift is simply a matter of time of flight.
Now what will vary, IMHO, is impact... the impact of a 338 vs a 224, will be much different when hitting the animal, though I have not shot small animals with big guns much.

"In addition, the greater mass of the bullet resists deflection (wind drift) better than lighter bullets."

In addition to what?

Who was the last guy to win the 1000 yard Wimbleton witha .22 or 6mm caliber rifle? Duh?

Wayne

It doesn't really fit what your after but I've been using my 260 with 140g MK's. It's consistant and does pretty well in the wind from my 26" barrel at 2850 fps. I think I'll try the 140g bergers this spring because of the higher BC. I'd go with a 260 over a 257 bob but that's just me, I'm a 6.5 fan.

I used to use my 6mm with 55g NBT's at 4050fps over Benchmark but I've had better luck past 500 with the 260.

Bb

Bb-now if you run 95 NBT's out of your 6 it'll do very well at range. I use the 55 NBT a bit out of my 6/06 but mainly for about 6 weeks a winter when I am trying to be pelt friendly on yotes.

The 95 Berger would be another excellent one to give a go.

Dober

You didn't answer the question. Do you think differing bullet weights with same B.C./launch velocity = differing wind deflection?

To move an object (bullet) out of it's path requires a force. Force (F) equals Mass (m) times acceleration (a) or F= m * a

So, yes, it takes a larger force (wind) to move a heavier bullet out of it's path than it does a lighter one. Happy now?

Wayne

True enough. Many a 'yote in the Horseshoe Hills has expired due to that exact combination.

Wayne

The answer is no.

Two bullets with the same BC and same muzzle velocity will drift the same regardless of bullet weight.
