280 Ackley or 284 Win

My wife's 270 has seen a lot of rounds so we were thinking about a re-barrel to one of these chamberings. This is a long action gun. Any thoughts about either one?

Apparently, the 284 with RL17 can really make the 168 Bergers scream.

Thanks.

Re: 280 Ackley or 284 Win

I would go to 6mmbr.com. They have some really good info on the 284 Winchester. It is a very appealing cartridge.

.280 Ackley. Winchester admits there was no reason to chamber the model 70 in the .284 because it had no advantage over the .270, back in the day.
The other reason? Try to find .284Win brass right now.
.280 Ackley brass is available pre-formed nowadays, and just about everybody carries it.

They're both good cartridges, but... if it were me... I would go with a 7 WSM since you already have the bolt for it. to go with eithe of the others, you need a new bolt or new bolt face. If you're concerned about barrel life, you can load it down a little and still have the ballistics of the others. Of the two you mentioned, I would go withe the Ackley. RL17 should work well with it also.

Re: 280 Ackley or 284 Win

Actually, I'd have to get a different bolt for the 7 WSM since my bolt face is currently 0.473". For brass, I was going to use 6.5-284 Lapua brass and neck it up. It's cheaper than the 280 AI Nosler brass.

It looks like the 280 AI case gives about 7-8% more case capacity though. Recoil is a concern too since this is for my wife. She's only 105# and has to pack it AND shoot it so it has to be light.

Thanks for the discussion so far.

You have two options at this point. Put a break on it, or use low power loads. I think that the 6.5x284 is a good option. You can get it in either Norma or Lapua. Lapua would be my choice. You can load with a 140grn or 150grn bullet and it would still be a hammer.

My apology, I thought I had read 270 WSM instead of 270. I have never shot a 280 AI,but have read that their recoil isn't real bad, but I wouldn't attempt to promise you anything. The 284 Win might be the way to go. The 7-08 with RL17 should also be a good option. But... then again, i'm not sure that 280 AI is going to kick much more than the 270 and you could put a decelerator recoil pad on it. It would be nice if she could shoot one first.
