Home Forums Hunting & Shooting Hunting Rifles Talk to me about cartridge conversions

And then......?

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx






I got one !
M 98, 21" blll., Timney, Boyd's Hardwood stock
60 grs Surplus 4831, 139 HBT, 3000 FPS



AND it works. I have a few more pix of deer it has stopped.

I like it. It's a keeper.

EDIT: In 2014 it was very difficult to find 284 Brass but one of OUR members here ... was gracious enuff to sell me
a sufficient # to supplement my supply. THANKS to our participant !!

Tikka feeds 7RM from the mags you'd be using.

I have to agree with others here that if your going to go .280 it might as well be .280 AI. Especially since you are never going to use factory ammo anyway.

If I ever succumb to loonyism again and set up a reloading bench, a .280 AI would be at the top of the list. I even agonized on the .280 AI vs. 30-06 as my one rifle.

Nice thing about the 280AI is that the SAAMI pressure is 65K for the AI versus 60K for the 280.

Not that you can't run a 280 at 65K, but you won't find pressure tested load data published for a 280 at 65K. You're left to guess.

Rethinking my original plan. I have a great load with 150 Eldx out of my 7mm-08 (2780 fps) and another great load with 162 Eldx out of my 7mm Rem Mag (2980 fps). A 280 really doesn’t get me anything I don’t already have.

Glad you WOKE, Bro.



Yes on your 7 RM......the 280 AI doesn't get you more ! EXCEPT expense.


Jerry

If I had a 7-08 that I liked, and a 7RM that I liked, there's no way I would build a 280 or 280AI.

But I don't, and the 280AI easily replaces both.

The 284 Win is a greatly under appreciated cartridge.

Common sense prevails......... The loonyism was getting out of hand in this one.

Not at same pressures

Jerry

Perhaps you missed this?




Not saying it's fully the equal of the 7RM, but it's so close it doesn't matter to me.

Couldn't a 25.06 be used and have it rebored to .280 a lot cheaper than rebarreling?

It's almost a letdown when a guy backs away from a Loony decision. Sometimes I feel like I come here to enable the Loony in others.

The 7mm-08 isn't a good comparison to the .280 AI since it is short action vs. long action and only has ~60% of the case capacity of the .280 AI). It is a great round, but is an apples to oranges comparison to the .280 AI in my opinion.

But the .280 AI and the 7mm RM are very similar in performance. The 7mm RM has more case capacity, but is less efficient than the .280 AI. But, as has been said, there is nothing the .280 AI will do that the 7mm RM won't also do. If you didn't already have a 7mm RM I would say get the .280 AI. Since you already have a 7mm RM, I don't think you are gaining anything by getting a .280 AI other than more load data to obsess over and a "new" rifle to play with.

.358/.366/.375 is calling....

My -06 is going begging in the classifieds, so how about a .338-06?

You could send your 06 to JES for a rebore to 338-06 for less than the cost of a new barrel as long as there's enough metal at the muzzle. Dies for the 338 A-square are likely to be cheaper than custom dies. I screwed a new 25" 338 barrel onto an 06 Stainless Stalker a few years ago. Since I was buying 1/2 the reamer it turned into an Ackley. Just started working with it again this year. With an older lot of WW nickle 280 brass, WLR, & a case full of H4350 it does 3000fps with the CT 200gr Ballistic Tip or the 210 Partition. Groups are at an inch or under with a 5x scope, so I'm sure it could do better with more scope or younger eyes. RL17 is also promising, & I wonder what Power Pro 2000 might do. It's Whelen with sleeker bullets.

Question in my mind the sensibility in doing a 280 AI in any action that does not have a 3.6" box. Having to load long slinky bullets short to work in a 3.34" box reduces your powder capacity gain that you AI for in the 1st place.. Figure the exact bullet you want to use, throat for it utilizing the 3.6" mag and keeping that bullet from intruding into the cases powder capacity.. std action at 3.34" doesn't seem to be the logical choice. Food for thought, somebody defend the idea of using the 3.34 action with rational please. MB

If you're going to rebore, I'd jump straight to 9.3X62. If you're gonna rebarrel, I'd give the 6.5 RPM a hard look.
