Home Forums Hunting & Shooting Hunting Rifles learn me about the 280 AI

Pretty much what I've gathered off these last two pages is that if we want a .284 of some flavor it better be 7mm Super Duper mag because a 7mm-08 isn't a .280 and a .280 will do everything/anthing that a .280ai will. And a .280ai just will never be a 7mm Rem mag, which in turn will never be a 7mm RUM, or a Mashburn or a or a STW. So there's really no point in all those lesser calibers because someone has taken more sh*ts in their life than the next person and they obviously know more about what you want to do than you do.


WHO CARES?? When someone tells me not to like something I like it even more.


When it comes down to it with todays scopes, ballistic aps, weather stations, etc. For shooting practical hunting ranges one isn't going to make a lick of difference over the other.

The only reason to build a .280AI instead of a 7RM..... is so you'll have a reason to talk with Friend Steve (Dogzapper) Timm. A man with more time behind the trigger of a .280AI cannot be found.... and you'd be hard pressed to find an all-around nicer guy. He will admit that the AI ain't the 7RM.... it's 'close' though.

I have had a couple of both.... and the 7RM is a better round as far as I'm concerned. I'd never trade a 7RM for a .280AI..... but I have done the converse.... twice.

Hello, my name is Troy and I am a loony. I know this because I read this stuff and keep coming back for more. What's troubling is I actually find it entertaining.

Okay, can we all just admit that the .280 A.I. is for dorky queers and the 7 Remington is the cat's azz? That's the only compromise I can think of to end this debate.

As far as 'pressure' is concerned.... here's how I see that... empirically. I currently shoot 63grains of RE 22 behind the 162Amax in my 24" 7RM. This load clocks 3000 and some change. Can you run a 24" .280AI to there? Probably..... BUT, how long will the brass last? I am on my 4th box of 162s with this lot of 50 brass.... and have not so much as bumped a shoulder... collet dies all the way.

The only pressure I know about is after eating college dining hall chili.... oh man.

Is this your coming out post?

Seems to me that boy is running a 7RM......

.280AI isn't for queers..... it's for overthinkers....

7 Rem here DT!

Hey tanner, gfy.

I joke, I joke...

Over compensating for something there son.....GFY

NICE!!!!!!!!!

If he were compensating.... He'd be shooting a RUM....

Yes. The .280 by a good margin.

In my .280 A.I. I run 60.5 of R22 under the 162 AMax and get a verified 3050fps from a 24" barrel. Book load that I assume was pressure tested as safe and shows zero signs of pressure in my gun. My data shows the brass has 7 loads on it and yet to find any issues with it.

Again not a 7RM but not as far off as some would think.

I have a load that will run a 162 at 3225 in my 7RM.... and show no pressure signs. Is that ok?

Depends on the gun of course. My 7RM hasnt fired 162 AMAX but its pet load is the 160 NAB right at 3200. book load 1.5grs under max. In your rifle it very well may be perfectly safe. My whole point is in the guessing that a guy is pushing a rifle too far that one has never personally handled.

When I developed my loads in my rifle I spoke to a Nosler ballistic technician, even sent pics of the fired brass and he said my loads were absolutely fine. During deer season this year I happened to stop into CCI/Blount as they are but 45 minutes from our hunting ground. Got talking rifles to one of their techs and he looked at my fired brass and said it looks fine.

7 loads into the brass with no bulging, thinning of the brass, primer pockets are right and no appreciable growth. So what If any indication do you have that I am over pressure?

Steve Timm who you admit probably has more trigger time then anyone on a .280 AI, Nosler tech, Barnes tech, CCI tech all say I'm NOT pushing the gun to the hairy edge but you claim I am? Interesting that the people who get paid to know this chit and likely have college degrees in it say its all good.

So yeah it's irritating that you propose folks like me are risking chit when actual ballistic techs who make their living doing this say I'm not pushing the Saami max very hard.

The thinly veiled claims and bkanket statements that those of us getting 3300 from a 140 or 3000 from a 162 are pushing the envelope of safety is plain asinine and your better then that.

Not all rifles or barrels are equal, I shoot 3 groove PacNors and tend to get 50-75 fps more then book speed with 1-1.5 grs less and work up and stop at the first even indication of pressure as I'm not dumb.
