280 AI

R23 has been immune to temp in my experience, plus decopper agent.

I should keep this to myself so I have less competition finding it.

I know nothing about the powder so I don't doubt you.

I will pick some up next time I see it though!

I f I where you change to a L R Standard primer with the Hammer bullet and you will increase the powder charge several grains increasing velocity. I switched all my loads from mag too L R primers in non mag case capacity's with a substantial velocity increase before pressuring out ,especially with the absolute Hammers , but it will apply too all in the 280 ai.

I worked all those loads up with 210 GMM.

The 215GMM ended up being the most accurate with the 119. I tried rem 9 1/2, Win LR, 210GMM and ended up on the 215GMM because it had the best groups.

I'm only able to get .5-1.0 grains more of powder with a 210z

The downside to 7828sc (likely RL23 as well), is that they are not very temperature stable

23 is about as stable as powder there is, way better than 22.

And no doubt barrel life improves.

I Expect the brass to last much longer also. I noticed very little effort was needed to resize them. As I have not found a steady supply of the brand of brass that I want, I'll have to make due with what I have onhand and make them last.

Agreed, fills the gap between H4350 and H1000 quite nicely.

Peterson, Hands Down!!

Agree 1000%. Peterson brass is what you want. Nosler is good and Hornady is terrible

I am a very basic reloader and just about ready to start some loads for my weatherby backcountry 2.0 in 280ai. The two powders i have on hand to try are 7828ssc and rl23. I really anticipated the 7828ssc was the better choice but reading this thread it looks like there are a lot rl23 fans. If you were me, understanding that i am a basic reloader, which powder should i start with?

Go with RL23. You won't be disappointed

Eurooptic is where I have bought 280ai Peterson Brass. They seem to always have it in stock. They have in 50 and 500 quantity. Not cheap but nothing related to hand loading is these days.

I 'm getting 2890 for accuracy with 168 vld hunter Berger's ,24 inch proof barrel. Reloder #17 , best groups .320 4 shots

I prefer the Peterson brand of brass.

Likewise!

I have 400 pieces of 280 new Remington brass that I am fire forming sometimes you have to take what you can get

23" IBI CF 1-7.5" twist. With a 140 AH and H100V I get 3300 FPS. Worked up close to 3400 FPS but groups opened up.

Theres a 280 AI group on FB. They have pdf files of quickload for a lot of popular bullets including the hammers. Based on what I have seen there that is a pretty hot load.

Absolute hammers are a radically different bullet design. Due to the lack of a traditional 'ogive', engraving pressure is drastically reduced, and a 140gr bullet behaves more like a 'typical' 120gr bullet - where internal ballistics are concerned anyway...

This thread is a good resource for those interested in learning more;

Absolute Hammer load data

I think this will work. @GLTaylor has been compiling load data from folks working up loads with the new Absolute Hammer bullets. Thanks to him for his hard work. I figured I would post it in a place where guys can find it more easily. If my link doesn't work then George can put his link in here.
