I was wondering if anyone on here has tried the new 6.5-300 Weatherby that is out on the market. I have always wanted a 257 Roberts but this round seems to be a bit more than that and if it shoots as they say flat and long it may be an alternative to the 257 Roberts. it shoots a 127 Grain Barnes LXR bullet at 3,531 fps.
What are your thoughts and if you are a re-loader is there a better bullet to shoot out of this rifle
 
I have one and shoots that Barnes bullet well,Barnes is coming out soon with some reloading Data soon.
 
The 6.5-300 is a pretty big step up from the .257 Roberts. Its a fast cartridge for sure. It burns a lot of powder though (twice as much as the .257), which means more expense to reload, more muzzle blast, and more recoil. And if you shoot a lot, barrel life will come into play. If you decide to go with this cartridge I'd lean toward the heavier bullets to take advantage of all that powder. 127s would be good but also check out the 143 Hornadys, 140 Bergers, 140 Accubonds, or 142 ABLRs.

The .264" caliber (6.5mm) is better in my opinion than the .257 because of the much wider selection of bullets available. Other cartridges I'd consider in this caliber would be .260 Rem, 6.5-284, 6.5-06, 264 Win Mag, or 26 Nosler. If a custom rifle is a possibility and you don't mind custom dies as well...you have even more options: 260 AI, 6.5-06 AI or 6.5 Sherman (both "improved" versions of the regular 6.5-06), 6.5 WSM, 6.5 SS.

Personally I'd do a 6.5-284, 6.5-06, or 6.5-06 improved. To me those have about the right amount of power for a .264" bullet. They'll push the 140s at 2900-3100 fps which is great for hunting most big game within reasonable distances. The larger cartridges would be better for really long range but I'd rather have a .30 or .338 for the longer pokes anyway.

Love those "Knockdown Power" questions, LOL!
 
No matter how much powder you put behind a 6.5 bullet 140 grains isn't much weight.

The 264 mag was put on the back burner because the 7mm mag out performed it so well over 50 years ago. the same is true today , no matter how much powder you put behind it 140 isn't enough weight .



The 7mm magnums offer better ballistics , bullet selection and versatility. all the 7 mags are good but if you really need something different the 28 Nosler is probably the most interesting thing to come along in a while. if it were me I'd look very hard at it. there are other 7 mags that do the same thing but the gun industry is driven by reinventing the wheel.

I agree with most of what's been said (not that anyone cares. ha)

The 6.5 mags are light-years different than the 257 Bob. The 257 is a mild mannered deer round but the hot 6.5's are freakin' animals on deer and antelope.

The 26 Nosler would make a fine deer-type cartridge whereas the 28 Nosler would make a fine deer/elk round.

Both the 26 and 28 are unique and proprietary rounds so stock up on brass right off the bat so in 10-15 years you're still shooting it.

Neither will have the best barrel life in the world and both burn lots of powder but powder is cheap and a new barrel isn't that much money. Besides, you won't be shooting it like a varmint rifle, I suppose. Most guys should get a decade or two out of the barrel.

With all that said, I've never shot either one but hang with a couple guys who use them. (specifically the 6.5 RUM, not Nosler, and the 28 Nosler)

I love the 6.5 WSM but you've got to be willing to mild wildcat.

My best rifle ever is my HS Precision 300 ultra mag,its a tack driver and kills what I shoot,why I buy other Calibers? because I can.
 
it's kinda like hats you always can use one more. I guess the 257 Roberts is a gun I always wanted to own because it is a good deer gun for both muley's and blacktails which don't take big guns to take down.
Also we hunt wild pigs here and I have friends that use the 257 Roberts and it is a fine gun for the wild pigs as well. You just don't shoot the meat all up, smaller exit holes
 
If you like to complicate your life, get a proprietary cartridge like the 26 Nosler. There is nothing like having to rely on a single source for brass and ammo. Too often the flavor of the day, turns into the nightmare of tomorrow, when you can't source brass.

There is much to be said for a chambering that can easily be found. The novelty and newness of the latest whiz-bang cartridge wears off and if that cartridge doesn't take off and become popular, you run the risk of it being abandoned altogether or only having small, seasonal runs of brass produced.

+1 When I invest in such a caliber I always buy 7- 8 boxes of ammo,but others might shoot more than I do.
 
Life is complicated and firearm/cartridge selection is too but let's do some math.

100 rounds of brass x 5+ refills = 500+ shots (you'll get way more than 5 loads out of your brass if you don't over-charge/pressure which expands the primer pocket and you don't set the shoulder back too much when you resize)

Once the load is developed and the scope is sighted in, you MIGHT shoot 50 per year out of a BIG gun (I'm sure most guys shoot less than that)..That's a 10+ year supply of brass so what's the big deal with proprietary ammo? If it's your only rifle then re-think the cartridge and lean toward something more vanilla.

So buy or build what you want and get 200 rounds of brass and have a 20 year supply of shooting pleasure.

If you're just a "buy ammo and shoot" guy and you don't reload, stay away from proprietary cartridges unless a parent case is readily available for case forming.

Remember this isn't your only rifle so that opens up the selection for you to get a little crazy.
