Anyone loaded for this caliber yet? Would appreciate your input.

If you have not bought it, don't. That is way too much case capacity for a 6.5 bullet at 99 grains. I have had two .264 WM which have a case capacity of 82 grains. Both barrel shot out in way under 1000 rounds. I am now replacing one with a 68 grain capacity 6.5 Remington Magnum. That is a much more useful powder capacity to bore, and I can get essentially the same velocities out of it as the .264. There are excellent bullets available in 6.5 mm. You just need to get the right size case behind them. The 6.5 RM is hard to find and get reloading components for. For someone considering a 6.5 I would suggest the 6.5-284 Winchester. Same case capacity, and brass is available. Some guns are now being chambered in it. Try to get a long action though as overall cartridge length with 140 grains will be too long for a short action.

If you already own the 6.5x300 then load'er up with a slow powder like H1000, or Retumbo, and put a new barrel on order right away!
 
It belongs to a friend. I would never buy an inefficient case as such.

Was thinking of 90 grains of US869 with 130 AB's. What do you think?

I also shot factory loads and it shoots horrible.

I don't understand this obsession with specialised chambering not lasting X amount of rounds before the barrel is pooched. If you can afford the rifle it is chambered in or if you can afford to build a custom one and litteraly put a couple tons of meat in the freezer with it before it is shot out, you can afford to have it rebarreled.
 
My 264's lasted way longer than a 1000 rounds. When I lose accuracy I take the copper out of the barrel and keep shooting. My old model 70 from 1959 with the factory stainless barrel has close to 3000 rounds through it and still shoots very well.

The barrel that is coming out of my Remington is factory stainless. It can't hold 3" at 100 yards anymore. Perhaps expectations of accuracy are different.

You probably need to get advice from someone with QuickLoad to get accurate reloading data. I gather this is an official offering from Weatherby, but I don't see any loads for it. Nosler have load data for their new Nosler 26 which comes in at about 6 less grains capacity of 93 compared to the Weatherby 99. Loads for the Nosler 26 are probably a safe starting point, and could be increased a little more based on pressure signs.

Based on the Nosler 26 data, I think 90 grains of US869 would be a safe starting load, and you could likely work up to 94 or so.

Oh ya, I forgot..........If you don't have anything positive to say don't say anything............this is how I get myself in sh!t all the time..........right?

So now that I have reminded myself of this...............Sir:
May I suggest you do a little more shooting and load testing before you post with such an authoritative aire............you make yourself look foolish !! I have built and shot many 264 WMs and the one I have now has more than 5000 rounds through it and it still shoots well under MOA. I played with a 6.5 and 7mm X300 Wby many years back but could not exceed the 264 WM because of the limited powders we had back then, but now a days, with the plethora of good slow powders for big cases, it's a whole new ballgame.
Also any barrels that you have removed because they are "shot out" with 1000 or so rounds through them, send them to me, I'll gladly pay the postage............

OP.........try US 869, H 50 BMG and Retumbo, or if you can find some new Alliant 50 something or other. My 7mm RUM and 300 RUM work best with Retumbo and you are in the same ballpark bore to case capacity. As for charge weights you can use loads for the 7 STW using the same bullet weight and start 10% below their starting charge and work up until you can read the pressure signs on your cases.

Not only. My pops has had his .264WM for over thirty years and has well over 3000 rounds down the pipe. Is it as accurate as it was in its prime? No, but it still shoots just a hair over MOA, which for a hunting rifle is still perfectly acceptable.
 
RonAKA; Me thinks you are spouting conjecture, not facts.

I have owned a number of 264 Win Mags over the years. None had the accuracy go south within 2000, let alone 1000 rounds.

I had a Lilja barrel put on a 700 Action, chambered in 264 Win Mag. When I changed that rifle over to a 308 Norma Mag,
it had 3500 rounds through it...still shot moa with the 140 Partition and 76 grains of old H5010. BTW, that load generated 3300 fps.

I have also owned 3 - 6.5 Remington mags, and there is no way on this earth that it will stay with the 264 Win Mag for velocity.
[See the above velocity for the 264.]

Weatherby magnums are race cars. Do not expect Prius mileage.

Sir;

My resume is well known on this site. I have posted many photos of chronograph print outs as well as many hunt outcomes, from over a lot of the planet. I have also posted pics of sub MOA groups I have shot as well as some that were not. I have just recently posted pics of my loading room and gun vault on another thread here.
Your "come back" is very poorly chosen, as many on this site know of the depth of my cartridge experimenting and design as well as my wildcatting and gunsmithing. Some have seen my set up and a few have shot with me. You have done none of these things and yet you have decided to blindly attempt to ridicule me in the most preposterous way. And yet again you only end up making yourself look foolish.
You sir, are the one posting ridiculous statements as though they are fact, when the facts, in reality do not support what you state. A 6.5 Rem Mag, or a 6.5-284 will NOT achieve the same velocity as a 264 Win Mag, from equal length barrels.........period. The 26 Nosler and the 6.5X300 Wby will exceed the 264 WM, by quite likely a significant margin using the newer powders we have.
I think it is becoming abundantly clear here who is in fact, the "internet" expert...........and given some of your other posts I have read of late, may even be the new "Sunray"

Strange, Douglas, I was thinking exactly the same thing, lol. Dave.

I was the first idiot now c-fbmi and Eagleye are. That Ron AKA sure knows a lot about 264's and like c-fbmi I would gladly take his copper fouled barrels. Maybe the he forgot to enter his whole user name? Ron Also Known As sunray
 
It would seem that possibly we have struck a nerve.................he's acting even more like sunray...........strike with inappropriate, or blatantly wrong comments, and then evaporate.........never to return and defend or rebut his position.
