In my opinion you are getting too caught up with "rapid expansion". Bullets expand on impact and travel through the. The difference you see is how much the expand or hold together.
A lot of people claim "penciling though" but this is very rarely the case. How many people with a naked eye...
Either one will work. Whichever your gun shoots better. The accubond would have higher BC but probably not much of a consideration unless shooting past 400 yards.
I've killed deer and elk with both. I think the partitions held together a bit better but didn't have any issues with either.
Have you tried looking at the blue book value.? It may give you a ball park at least. Then compare to Gun Broker. Yes chambering changes price but should give you an idea.
It being marked 7mm Express probably makes it worth a bit more to the right buyer. Depends how patient you want to be.
I've never had blown primers from factory ammo. Normally it would be worn primer pockets or too hot of a load. Not sure on the factory ammo.
Try some other ammo to make sure it's not something with the rifle. If other ammo is fine I would reach out to Federal to see if they had issues with...
I read it and chose to ignore it. It wasn't bad but not productive. I think you choosing to voluntarily removing it shows great character. Don't see that often on Internet forums.
Older thread but I'd say it is clearly working for them.
I bought some solid base component bullets to use in my 7x57 Mauser. It's a 95 Mauser so I keep pressures low. Like a simple bullet for it and this should work.
I see it as a good option for people to buy some practice ammo and have...
It sounds like other primers work just fine. Might be worth emailing Remington and providing the lot number. Just confirm they didn't have a bad batch or anything. If they did they should replace.
Probably not the case but for the time it takes to send one email worth it in my mind.
I guess I would say there is no need to switch from the 280 Rem if you are happy with it. Me personally though if I am rebarreling anyway I would do the 280 Ackley Improved. Pick whichever you like and be happy with it.
If you are rebarreling anyway I agree with JD338. You may as well get a 208 Ackley Improved. Get 100-200 fps more. You can fire form your 280 Rem brass and I think 280 AI factory ammo is just as available (though maybe more $).
I have a 270 win with a barrel almost shot out. I'm debating...
