280 ackley imp loads

[DCAN]

Looking for info on RL26 and 280 ack imp loads. Have been using H4350 and was thinking of trying something new.

 

[BEEMAN]

Tagging in. I would also like to try some R26. Currently I'm using H4831SC with 168 classic hunters.

I've never reloaded for my AI. I need to start. So any powders with ranges will be nice. I know start lower cuz all guns are different. But I have retumbo and h1000 and some 4350 and 483-sc

I think on the 7977 enduron Or IMR wich ever you want to call it they say works great in 280AI.

Most of the time I've had better luck w/ IMR4831 w/ the 150's-160+ grain bullets, and RL22. IMR7828 for the 175 NPT which I know a lot of people may think it's outdated, same might say for the 150 BT, but they still just plain work.

RL26 is basically RL25 which is/was a very slow powder, I'd assume you'd want a fast twist with a heavy for caliber bullet.

Oh, I have used H4350 to fire form loads, it's better suited to the 140-150 grain bullets IMO, but I have tried it w/the 162 ELD-X. So-so for me, but my rifle is only a 1:10". I didn't see a real need to burn up bullets, or the powder down my barrel anymore, been there done that years ago with this gun, and why I went to test all the newer stuff was beyond me!

Thanks for the info. I've been using Barnes bullets up till now. This is my spring bear gun and with the Barnes bullets it kills like Thor's hammer! But not being able to leave well enough alone, I just can't resist tinkering.

I have a load I developed years ago when the TSX's first came out I still use to this day w/RL22 and the 160 TSX FB in my 280 AI, works great.... nothing has ever walked away.

I am a big fan of the 7mm rounds

Love the 28 nosler and the 280ai, would like to get a Kimber but have read a lot about the accuracy in these super light guns??

 

[LittleMike]

I'm using the Nosler 140 & 160gr Accubonds with IMR4831, I'd be interested in comments and load data folks have using H4350, I don't find any load data in my books.

 

[Dmagna]

I use H4831sc and 140 accubond. I would never use rl22 in a hunting rifle in my state, way to much temp sensitivity with that stuff. I have the 140 going to 3200fps, it's only a whitetail/black bear gun so 140s are perfect.

Was just curious if anyone has any experience with Vihtavouri Powders, specifically the N540, when reloading their 280 AI. Im new to the 280 world and had really good luck using this powder in other calibers. Have a bunch on hand and didnt wanna get into having a bunch of differnt ones speciffically for different calibers. Dropped my action off today to get the custom barrel installed, have never even fired this caliber. just trying to get some general ideas for when its finished and start load development. Prob gonna be running something around a 150-160 gr bullet

Might be a little too fast of powder for the 150-160 gr bullets. Not sure what barrel length your shooting but may need to start with N555-560 for the 150-160 weight pills. With monos you might hit it with a faster powder like N540 with 150 monos depending on barrel length. Great cartridge!

They have an app but only the 280 is listed not the AI and the fastest powder listed is N550 for the 140s. I'm currently running a 140 mono with H4350 which is similar to N555. As stated i think N540 is too fast, I'm currently running that in a 22arc.
