Picked up a 2 lb canister to try in my 280AI but I cant find any load data. Anybody have a recipe?
Thanks is advance.

what weight bullets?

I would like to use 140gr.

Sierra lists starting load at 49.8gr at 2700 and max is 59.7 at 3000. I have no experience with this powder so I couldn't recommend anything about it prom personal experiences. good luck

There is a campfire load floating around that is considerably higher than that, and it is HOT!

The "Borden" load is 63.5gr with 140grNBT for 3200ish fps.

blew a primer in mine with that load.
be careful.

Nosler manual #4 has 280 AI loads.

It lists N 165 for the 150 gr. Partition: Starting load is 57.0 gr. and MAX Load is 61.0.

For the 160 gr. Partition,and Ni65, it lists a Starting Load of 55.0 and a MAX Load of 59.0

For 175 Partition, Starting Load of N165 is 52.0, and MAX Load is 56.0.

N160, rather than N165, was used for the 120 and 140 gr. weight bullets. For the loads listed, cases were Remington, and the Federal 210 Primer was used.

This is the place where I usually say:
You did it backwards; buy the manual with the 280AI loads first and then buy the powder.

P.S. Can you see why that fellow poster blew a primer?

Win a new Weatherby with the correct answer!

it was only 1 out of 5 rounds.

didn't notice it until later. which one it was ? weak case ?
dunno, but when i saw it missing, i didn't go back to that powder or load.
btw, 63.0 shot fine, it was that .5 grain more...

imr4350 shot way better in my rifle so i stuck with it.

I grabbed the powder because it was a great deal, I have the Nosler manual but just wanted to see if anyone was using it for 140 gr. weight bullets. I have been using H4831sc and I don't usually go outside of the Hogdon family because I haven't found anything that much better. I took a gamble, we'll see how it works.

Gee, if you already have the Nosler #4, why didn't you say so to start with, AND save a person like me from re-typing all that manual information you already have?!!

Do you think perhaps that was rude of you, or lazy, or discourteous....?

splattermatic:

Guess what: It wasn't a weak case, it was an overload!

If one is loading a wildcat cartridge for starters, and knowingly at the near maximum for that wildcat, the process is to inspect each case after firing.... One does not "notice it until later".

Not only do you NOT win a new Weatherby, please surrender your car keys to the range officer, and walk home carrying all your gear. You will have learned something by the time you reach your front door.

buckeye- My sincerest apologies in not being more forthcoming about my ownership of the manual. I should have been more specific that I was looking for 140 gr. load data.
I don't think I was being lazy rude or discourteous it was an oversight, but thanks for all your help, I didn't mean to make you re-type information when you could have been answering someone else's questions elsewhere.

I treat it like it's R22, but it's actually just maybe a wee touch slower IME. In my 280 (Not AI) I ran 61grs of N165 behind 140s.

Vv 165 is the powder of choice in my 6.5-284. Not sure about the .280AI. I find it clean burning and in my gun, very accurate with low S.D.'s.

Good stuff.

That's the hallmark of VV powders IME. Consistent velocity.

The Nosler #6 list a 150g Partition N165 max load as 63.0gr.

I have been using the Borden recommended load in my 280AI timberline for a while now. 63.5gr gets me 3160fps with a 140 AB. That's with CCI200's and Remington Brass. I'm on my 5th loading of the brass and still have tight primer pockets.

When working up loads for the 140AB I used Re19, Re22, H4381sc and VV N165. All the powders gave me really good groups but the N165 load was exceptional. Re22 gave me the best speed though.

Quite a few people I know use the Borden load. That doesn't mean it will be safe in your rifle so work the load up. Nosler #6 Has a bunch of really good data on the 280AI.

In my 6.5-284, RL-17 was faster than Vv 165, but couldn't match the accuracy. I have a turret scope, calibrated out to 600+ yds. I don't need velocity as much as I need pin point accuracy. In that gun, anyway, Vv 165 rules.

I understand that some of the serious long range competitors use Vv 165 in the 6.5-284.

The 280 AI has more case capacity than the 6.5-284, which is closer to the std. 280.

Ilhead 71:

Your apology is accepted.

I will try to NOT answer anyone's reloading questions, here or elsewhere, and I expect many will be pleased at that.....

[Exceptions will be made for those who are really close to blowing themselves/others up]

I wonder where Borden got that load......grin

I got that load from Tim in TN when I first put my 280AI together. 140 Nosler AB, CCI BR2, 63.5 gr VV 165= wonderfully accurate load in my rifle, average for 7 3 shot groups is .5". as with anything rifles vary work up carefully

Thanks, I am going to work up this load in my rifle starting at 60 grains and go 0.5 up to 63.5 and monitor pressure signs.

I shoot the Kenny Jarrett/Borden load just fine in mine but I use Win. Nickle brass that has the largest capacity of any 280 brass and my rifle is long throated for 168 Sierras. We borrowed the reamer from a Silhoutte shooter.

N165, R22, MRP have all been great in the 280AI but am now trying R26 so I can cut down my powder inventory. Looking good so far can equall or exceed velocity of the others and I think I will eventually get back to the same accuracy of the others. But can't go wrong with any of them.
