BC - is a placebo for marksmanship.
GR You’re like a broken record; except the record isn’t what you think it is. Your feelings. Care to expand on them? GR Lacking. Like your understanding of “placebo.” I think the correct word should have been "panacea" rather than "placebo". No, placebo. ... something that you think cures something... but actually does nothing. BC - is a placebo for Marksmanship. Exactly correct. GR

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.................. This is the POT at the end of the Rainbow!!!! Buy up 10 boxes of the 180 eld-M when you get a chance, find a gunsmith with a unithroater, throat accordingly. Then you have a Leg up on a lot of JUNK! Even the lowly 280 with the 180 ELD-M walks off and leaves a lot of JUNK in the dust! Lapua 30/06 brass for the start, and you can not kill it! Learning curve is a bitch, took me a while, I used to shoot 139 Hornady and 140g Ballistic tips in the 280,AI, and 7 Mag. I throated them all out for the 180g ELDM.

A 9.5” twist 7WSM will stabilize the 180 ELD, but you’re giving up some BC. Go 8” or faster.

Might build a custom rifle, Talking to the builder about calibers and he mentioned the popularity of the .280 AI
If you own/owned one, tell about it’s like and dislikes. I like the cartridge. I didn't like the recoil. Next time around I'm going with a heavier rifle or a brake. Last was a Kimber Montana. 6-1/2 to 6-3/4 pounds with a Leupold 3.5-10X in Talleys aboard. That's too light for something that thinks it's a 7mm mag .. only falls 50 fps or so short. Tom

The Kimber's bane is itty-bitty COAL latitude,though they'd likely make a fine high RPM Six Twat-Six donor. Hint. Fhuqking LAUGHING!...............

I am at 500 ft elevation, all of mine are 9 Twists, also in a Rem 700 factory sporter in 7 Mag. I have 8.5 and 8.75 in reserve, waiting their turn.

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. Build a .280 Rem and go hunting.

Tom Agreed on the weight issue, There’s a balance beam effect here, I’m looking for a mid-weight hunting rifle,,,,7.5-7.75 lbs scoped, heavy enough to enjoy taking to the range,,I do shoot my rifles,,,, Light enough that I’ll call it my ‘mountain rifle’. I had mentioned 150ish grain bullets, I like Barnes monos, they kill, The conversation then went towards 180 grain target bullets, yes I know there’s ELD expanding bullets, Then to fully utilize these long range high BC bullets, I’d think you’d want a reliable turret twisting scope, Then the weight issue comes back into play,,, But all in all, appreciate everyone’s comments.

I like the 280, 280AI & the 7mm RM. there’s not enough difference with these to make a difference for me. I have multiple 280’s (7mm Express), one 280 AI and a couple 7mm RM’s. I tried to let go of one of the 7mm RM’s but for some reason people seem to think of the cartridge as the red-headed child.
I prefer classic. Semper Fi I used to run with the hare. Now I'm envious of the tortoise and I do my own stunts but rarely intentionally

I have a factory Kimber 280ai... shot deer with it I built a Sav 110 280ai with Bartlein...shot targets I built a 1949 Win M70 in 280ai with Bartlein...shot antelope I built a 1930 Braz Mauser 280ai with Pac Nor...have not shot it yet. I think the 280AI is a fine hunting cartridge.

I had my first ,280 AI built in 1986. M700 Douglas air gaged no4. 1-10. The load I ran was 140g ballistic tip over 64g of H4831. Figure 3140fps. This from a time when BTs we're bombs. I hunted deer all over North America and Canada for 15 years and never had a complaint. No clicken. No dicken. Nothing within 500 yards was safe. You can run all the gack stuff you want. For deer and similar sized animals. And now with factory cases and mono bullets. It's solid performer it's hard to beat. dave
Only accurate rifles are interesting.

A good 700 or a 70 with a 3.6” box is a wholly capable rig in my book for fillin the meat locker.
