Home Forums Hunting & Shooting Custom Rifles & Wildcats .280 Ackley Improved,,your thoughts please….

Might build a custom rifle, Talking to the builder about calibers and he mentioned the popularity of the .280 AI

I’ve never really looked at that cartridge before but I see where it has several benefits to it,

Decent amount of reloading data available.
Good factory brass available,
Good selection of bullets from several manufacturers,
Uses moderate amounts of common powders, H4350. IMR 4350. Etc…

Looks like we could hit about 3000 fps with a 24 inch barrel and a 150 grain bullet?

I believe 1-8 twist barrel is what we talked about

Any other cartridge I might be looking at?

If you own/owned one, tell about it’s like and dislikes.

I am selling my Kenny Jarrett 280ai bean field rifle if you are interested : Real nice rifle with Swarovski 6x24 scope. Loads of brass, bullets , Jarrett loaded ammo that they developed for the rifle and dies

Read up on his writing on his 280ai in the link below. It is pretty interesting

I’m left handed, and looking for a left handed rifle.

A 280AI with handloaded 150's,can't hang with a 264 Kreed and Factory Fodder. Hint.

Give bullets a farrrrrrr greater thunk,than you have thus far and simply connect dots by default. Hint.................

Fantastic cartridge. I have had 4 LH bolts in this, and have one now. Best '06 based cartridge, and high on the list of best 7mm as well.


Or, use a 7mm-08 on a 416 Rigby length action with 195 grain bullets, if chasing BC, BS, and smoochies is your fantasy.

In the real world, the 280 AI will serve you very well.

KenBitchagain,

What were the "odds",that besides being a Drooling CLUELESS Fhuqktard,that you just "happen" to be a Lying Piece Of Fhuqking Schit to boot...you "lucky" kchunt. Hint. Congratulations?!?



Fortunately for you,Imagination and Pretend are free,so even you can "afford" to "contribute". Hint.

Fhuqking LAUGHING!....................

I built one on a pre 64 M70 action/MCM stock and am very happy with how it turned out. I shoot 145 LRX at 3050 FPS. use it for deer/elk.

I have a 264 Kreed, And now I’m thinking I might like a .280 AI

I thought you used to be a big fan of the 7s?

Love love love my Jarrett 280AI. I’ve had two of them. I get 3213 fps with 140 grain Ballistic Tips and right at 3000 fps with 150’s in my current Jarrett. She just shoots little bugholes. Last years final sight in before hunting season my four shot group went 0.081”. RL-23 is it’s preferred powder.

I lusted after one hard in the 90's. Never built one. Later, wiser lol - I have no interest.

If I was married to a 7mm (I'm not) - I don't know why I'd go 150 grain. I'd be 162 Amax or if needing/wanting some other construction or speed 120 TTSX and it would be 7-08. Modest even more on powder and great Lapua brass available. When/should I shoot out the barrel on my Montana - it's going to be duped but 6.5 Creed to replace it though.

Unless you are planning to shoot regularly over 400 yards?

Just seems like a lota fuss, when the .270 Win. will do the same inside of that.

And a 1:8 twist .270 Win. might even give it a run w/ the newer bullet offerings.

I believe his hint regards bullets, not caliber or cartridge.

Thinking BC:

6.5 143 eldx is .625
6.5 147 eldm is .697

7mm 150 eldx is .574
7mm 175 eldx is .689
7mm 180 eldm is .796


Changing the bullet changes the comparison. Of course factor in speed, powder wieght, etc...whatever factors are important to you. 175 7mm from a 280AI is going to be ~ the same speed as a 147 6.5 from a CM.....and things are getting on a more even comparison flight wise.

The 145LRX has a BC of .486 and is fhuqking dismal. Hint.

The 140 and 150 NBT's,are shy of that. Hint.

The 8" RPM .277" has NOTHING going for it and the 170gr Berger's BC is .662. Again shy of Factory Kreed. Hint.

'CUBIC connects dots and at like pressure,the 280AI will arrange the 175gr .689 BC,at Kreed 147 .697 BC speeds. If duping same,warrants a transition to a long action and horns you up...simply have your way. The increase in recoil,cost,loudness,weight and the like,do not "bolster" results. Hint.

Now the .284" 180 and their .796 BC,are simply fhuqking splendid and 190's at .838 even more so. Hint.



Bullets matter MOST ladies. Hint..................

To a hunting rifle and marksman... BC's are so much barbie doll clothes.

Enjoy them, if that's your thing.


The game will taste the same, regardless.

Even w/ good ole flat-based PSP bullets.




GR

Given where Stick hunts - literally 1/2 the time/days during hunting season, they see winds greater than 17mph. BC and wind drift are a concern. Over 20 days a month with wind speeds over 12 mph. At range - it matters.

It is a Crying CLUELESS Karen constant,that ballistic coefficient is a "Dirty Word!",despite EVERY projectile having a form of said designator. Hint.

BC factors drop,drift,impact velocity and certainly terminal effects,to the perpetual chagrin of Melting Snowflakes the World over. Starting velocity,isn't impact velocity and it's never not HILARIOUS,to grant Clueless Drooltards the opportunity to quantify their Fhuqktardation. Hint.

Pardon my being afforded the luxuries of not being forced to guess,due the simplistic fact that I shoot it all. Hint.

Fhuqking LAUGHING!................

So, aiming 16" into the wind at 400 yards is a problem?

Already aiming 2' high as it is.

The game will taste the same.




GR

I’ll take all the cheat I can within reason.

Assumes you can correctly call the wind - EVERY time. BC helps make mistakes smaller at the other end.

BC - doesn't replace marksmanship.

The game will taste the same.
