243 vs 6mm vs?

The 7mm's have the best bc available under .30 and
that 's alot of gun on a pd.,all things considered
I'd go withthe .243. if you are not a hand-loader
there is alot more facatory ammo out there for a .243
than anything else mentioned. If you are a hand loader
let your skills guide you. The 25-06 can be awesome
if loaded right, and not getting into a wildcat.
good luck.

I have both 243 and 6mm remington in remington 700.I roll my own and I personally like the 243 better. Now I didnt claim to know every thing but with a short action rifle in 6mm you cant seat the bullet next to lands as it will not fit in the magazine.Unlees you want a single shot bolt gun. I have experenced using varget powder that you can load both rounds the same and see high pressure signs in both with same powder charge. If I am doing something wrong with the 6mm that it is not out preforming the 243 please advise and I will do something different. I can seat the bullet on the 243 were ever I want and it still fits mag.Also you can buy 243 shells any were.
 
High BC is fine but an equally important part of the equation is you want a bullet that expands and puts a solid whomp on them and doesn't just pencil through. I'd be thinking A-Max in either a fast twist 22-250 AI or 243,243 AI. Retained velocity and whomp is king. The 25 06 with 75 gr. V-Max's or 85 gr. NBT's aint no slouch either.
 
I would prefer a 6mm AI, my uncle had one and it was pretty hot. The 223 WSSM should be just as hot, but you probably would not want a factory chrome lined barrel. A 25-06 would also be a great choice. Im not to hot on the 25 WSSM, to me the cartridge is alittle small but it is another option. I would also consider a 6.5 WSM with lee making dies for like $30. So get a savage in 270-300 WSM take the barrel off and get you a WSSM or WSM barrel and go to town, that way you do not have a restrictive magazine like any WSSM rifle. And you have a big game rifle also if needed. You will want a 26" heavy barrel, even in the factory barrel just in case and they sell for more also.
 
My 25-06 likes the 85 grain Nosler ballistic tips. I have heard very little about the 6.5-284, tell me more about it please. I reload every center fire I shoot so that is not a problem. I am open for other calibers if it will do the job better. I am not against recoil, I hunt elk with a 338, but I find myself liking the lower recoil rifles so that I can see the hit better. Thanks for all the responses, this is great!I always enjoy hearing from those that actually shoot the longer ranges as that is where I seem to be going.
 
IMHO, if it does the number on game, you ain't gonna see it happen in the scope.
I"ve killed a lot of deer with the 6mm Rem. and I've never shot a 243 Win.
I'm sure they are pretty much the same.

The 26/06 is above the both of them.

Mine shoots about anything well. With its selected loads, It shoots exceptional. It's a factory fluted sporter BDL.

Don't yell BS, I have the box it came in and it has that moniker right on the label.

I love it and I have not shot 10 rounds through it in the last couple of years.

25/06 is alot of fun, just make it happen.
PM me and I'll try to help you out.

All these suggestions r right on really. The real secret to making those kind of connections is getting a firm grip on internal, external, and terminal ballistics, understanding optics applications for intermediate to long-range shooting, and gathering and understanding the proper gear for this pursuit. What u need to become really for lack of another term is a "hunter-sniper." The application of "tactical-type" systems in the field that will allow u to put just about every round into a 6" diameter vital zone at the longest practical range under varying conditions is what it's all about.

Do u live someplace where they have sniper and practical shooting matches where u run a roving field course engaging silhouette tgts. at unknown ranges?? This is the best kind of practice for intermediate- long-range shooting. Log into longrangehunting.com, and precisionlongrangehunter.com for more info than u'll need.
 
Sidewinder,
The 6.5-.284 is nothing more than the .284 Winchester necked down to take .264 bullets. It's probably the most popular offspring of the ill fated .284. It is (last time I looked) the favorite 1000 yard bench rest cartridge. Until lately cases were necked down .284 but now you can buy correctly headstamped brass form Hornady, Lapua and Norma. The BR clan shoot the 139 to 142 grain bullets and load them to stay super sonic past 1K yards. It's also a great long range hunting round for deer sized critters with velocities approaching the .264 Win. mag. and better accuracy! I hope this helps. If you would like more info/load data shoot me a PM.

The problem with some of these choices, mostly the 6.5 x .284 or 6 x .284 is that you will need a very long barrel to burn that much powder. Here is the way I would go: the brand new Lapua 6.5 x 47 necked to 6mm. You can use a 24 inch 3 countour and if you twist it at 1 in 8 you can actually beat the 6.5 x .284 with 105 and 107 high B.C. bullets. The drop is less at 1000 yards and the windage (which is the real problem hitting past 600 yards) is much better. You will see a lot of guys trading in their 6.5 x .284 for this new round. It is VERY accurate and has little recoil. The brass quality is tremendous. Reamers are out there already and one guy has already won a match with one. Check it out at www.6mmbr.com

Good Luck
 
As I see it if the 6MM 284 has a fast twist you have no BC or LD advantage. The 6MM 284 has produced quiet a bit of respect in the 1000 yard BR ranks I think Mr. Shehane can attest to that.
 
The 6.5 X 47 is only a new cartridge to the U.S. It's been a popular round in Europe forever.

Since guys here started playing with the 6.5 X 284 (and 6.5-06) I've wondered why someone didn't start importing the caliber here. As you say, it matches or beats either of the American wildcats in a factory loading.

Very interesting article, thanks.

Mod,
You are confusing the Lapua round with the old Swiss Match. This is a brand new round. The 6mm x .284 is a barrel burner and ment for folks who compete and can afford it, i.e. Mr. Bill. It is not a practical round for varmint shooting and practice (which you will need to do a lot of) to shoot past 600 yards. Here is what she can do:

Wouldn't be the first time I've been confused Steve.

How is the Lapua 6.5 X 47 (not the 6mm) different than the old 6.5 X 47? I know the ballistics on the old round always made me wonder why we (Americans) were wildcatting rounds that were ballistically the same (or not quite as good) as already existing factory rounds. I assume the Lapua offering is even better?

At 600yds a 243 doesn't have enough energy to reliably anchor coyotes. Something like a 25-06, 7mm-08, or a 308 would likely be a better choice.

Don't forget that even hitting the coyote at that range will be much harder than you imagine in "field conditions" and you'll want to be packing a bunch of "whallop" to anchor him in case your shot placement is sloppy which it likely will be at that range.

My personal loooong range coyote rifle is a Remington Sendero in 300 Short Action Ultra Mag. I know it's a brute to shoot but I doubt the coyotes will escape it's nasty bite if I do my part.

Idhunter,
I kindly disagree with you on not enought energy. I shoot 87gr V-Max @3250 out of my 6mmREM. The 243win will be very close in velocity. Anyway 87gr V-Max,B.C. .400 @ 3250 has 719fpe @ 600, 590fpe @ 700, 482fpe @ 800. Which in my humble opinion is plenty of energy to hammer a yote.

I do very much agree that shot placement is a major factor in the equation. Although the thaught that "bigger" bullet is gonna cure all ills is a bit misleading. A 180gr 30cal in the guts is hardly gonna bring them down any faster than 6mm in the guts

Just my $.02
 
I was watching a hunting show where an antelope was a bang flop at over 500 yards with a 243. I have noticed that nobody is talking much about the 243 short mag, is it not performing well??
 
Here's 1 i'd like to play with some that'll come real close to that 243/6mm capacity/87 V-Max combination.

A D-Tech upper in 223 WSSM, and talk Steve Milholland of Swampworks into gearing up the 22 JLK Low Drags again. His 65 gr. LD has a BC of .395. That's the highest BC for it's weight of any 22 cal i've ever heard of. U could drive this bullet at around 3650 mv-- maybe a bit better. Here's the stats on it relative to the 3250 87 V-Max with a 250 yd. zero @ 5000 fps elev. 45 degrees--

65 JLK
