This forum discusses some BIG calibers for long range duty. I don't think I want a .338-416, a 408 Cheyenne, or a .50 BMG.
I want to carry a 10# rifle on my back with a 26-28 inch barrel, and have some 1K capability.
I have heard passing discussion of the 6.5-284, and have wondered about the .260 Remington and the possibility of a 6.5 WSM for long-range duty. My question is this: What sub-.30 caliber cartridge is, in your opinion, the best for long-range duty, and why? What is the big deal about the 6.5-284? Why is it so good?
I assume you are also wanting a short action? If not the 7 STW, 7 Rem Mag, 7 Ultra, 7x300, 6.5x300, 6.5 Gibbs, 6.5/06 Imp are all very good, if you want to go to a long action.
The 6.5 x 284 is popular, imho, due to the fact that the 6.5 bullets generally offer a very good BC for a smaller diam bullet. It also doesn't hurt that Daivd Tubb uses this caliber.
There are a lot of sub 30 cal rounds that can be used for LR shooting. Check out the results page on Steve Shelp's page. It list the calibers used by all of the competitors, maybe this will give you more idea's.
The biggest handicapp is going to be rifle weight, if you are talking about a rifle that weighs 10# total (loaded, scope and sling). The initial rifle will have to weigh apporx 8#'s naked. With a 26-28" barrel, it will have to be a very small diam, and this is not condusive to accuracy (do to barrel heat/disepation, stifness etc.)
I am not saying it can't be done, just very difficult.
I hope this helps.
Learn from others mistakes, you won't live long enough to make them all yourself
There are a few of them out there.6.5-300.The 7-300.My carry gun is a 9 pound 7mm STW with a 27" 9 twist Douglas barrel.I have shot that gun out to 1250 yard's.(at rock's)And I can say that It would not have any trouble taking a deer at 1000 yard's.The 6.5-284 from what I here is probably one of the most accurate round's on earth.I just like to have a little more down range energy

Your profile says that you're from Utah. I'm assuming that you want this rifle as a carry around gun for medium to large game hunting (mulies and elk).....
I have a 30-378 Weatherby Mark V and consider it to be perfectly suited to the type of hunting that is encountered in the west.
I've had it for 3 years now and have shot it very little because it's a horrible throat burner but it's a HUNTING RIFLE and I only shoot it about 60 rounds per year. It's probably only good to about 600 rounds before throat erosion starts degrading accuracy.
I know that you were asking for sub 30 caliber recommendations but when you want to carry enough energy way out there.... 30 caliber is a great choice and IMO you'll have a hard time delivering enough accuracy with adequate energy with 6mm or 6.5mm at long ranges.
btw... These rifles come with a very good factory muzzle brake that tames the recoil to quite manageable levels but is horribly loud and you absolutely should never, ever, shoot it without very good hearing protection.
I compare the felt recoil with this rifle to my Remington Model 7 chambered in .308 (no brake)
If it's long it can't be wrong... LDHunter (Long Distance Hunter) from the Piney Woods of NW Florida. I hunt clearcuts for scrawny whitetails... ;)
This would be a rifle for game deer-sized and smaller, and for general target shooting out to 1K. I want a caliber that will give more barrel life than a .30-378 would. I have considered the big calibers with muzzlebrakes, but just don't want to go that route. I just had a muzzlebrake cut off of my .338 WM. I want this rifle to be compact, relatively lightweight, and VERY accurate, while giving me some good medium-long range capability.
Do any of you know anybody who has developed and used a 6.5 WSM? I would be interested to know how it has performed for them.
A good barrel about 1.200" to 1.175" at breach to .700" to .750" at the muzzle at 26" to 28" long, with a 2" to 2 1/4" wide forearm that is about 1 3/8" deep at the front end on a good action pillar bedded and a good light scope (B&L Elite, Leupold LR, etc) will come to about 12 lbs. I think Boyd Heaton and 338 Lapua are right-on about the calibers. The 7mm Wby and the much maligned 264 Win are also good with good chambers and no freebore. Also consider 8" twists for the 6.5s--the extra torque helps kill. The 6.5/300 WSM just might fill the bill, I don't know much about it.
Look into the 6.5/284.. will get you to 900+ yards with the 142 gr. SMK and lapua makes brass for it. Matter of fact I am SERIOUSLY considering it as we speak....
very accurate form what lots and lots have said... carries speed and ft. lbs. very well and not a BIG recoil!!!!
