Reloading .280 Ackley Improved: Testing 140gr Nosler BT and 160gr

[@ozark_trapper]

I have been told by several 280AI shooters. The Ramshot Grand works good in the 280AI. I done load development with IMR 7828ssc. You have me interested on the bulk powder on American Reloading. I enjoy your videos!!

I also have a Tikka barrelled in 280ai, 24inch. Having great luck with 168gr ABLR and 160gr Hornady CX with N560. The ABLR's seem to have the ballistic sweet spot for this cartridge. Both around 2925-2950fps.

Thanks for sharing the details.

Looks great! I really need to get a 280 AI

[@RON-m8c]

😁 Yes, But When? 🤷‍♂️

Some Great groups, my friend. Thank you for posting your findings with your 280-Rem-AI. You cant go wrong with Leopold optics. I absolutely love my 280-Rem-AI . My rifle is a 26in 1:9 twist heavy barrel 9.lb rifle without the scope. I mainly shoot Brass or copper monolithic bullets and I don't shoot anything over 162gr for hunting. I do not like Horndys garbage ammo it is more Hype than performance all marking. Hell Plain jane Remington core-lock ammo shoots better than Horndy ammo any day of the week . I also like the swift scirocco bullets their devastating. I shoot Hammer & Barnes bullets a lot. Maker-bullets and cutting-edge bullets are phenomenal. Nosler and Sierra bullets are great also . You know Horndy copied Nosler with their polymer tip or Ballistic-Tips bullets. I am that guy that likes longer barrels no less than 25in on bolt-guns unless it's a scout rifle or carbine , Lever-action or AR style rifles. I look at it like this if I can run it hot and it groups good under 1/2-inch or less I roll with it . If not I'll slow it down or speed it up until I find my best accuracy node and roll with it. I enjoy the efficiency longer brass life and extra horsepower so much I Ackley improved quite a few of my rifles. Like 22-250-AI , 220-swift-AI, 243-win-AI , 6mm-Rem-AI , 257-Roberts-AI , 25-06-AI , 25-SAUM , 6.5-SAUM, 6.5-Rem-mag-AI-short action 6.5-06-AI , 260-Rem-AI, 270-win-AI , 270-WSM imp 40° sholder, of course 280-Rem-AI , 7mm08-AI , 30-06-AI and 338-06-AI exc. The best part of Ackley improved I can still shoot factory ammo and it automatically fire forms for reloading with way less brass trimming and prep. Thanks again for posting you results. God bless you and your family.God bless America 🇺🇸🇨🇱 🇺🇲🇨🇱 🇨🇱🇺🇲🇨🇱🇺🇲🇨🇱.

@@jeremystyron9721 yea I’m a fan of longer barrels for bolt guns and you’re spot on about the fire forming ease of shooting the “parent” cartridge through the Ackley chambering. I think that’s an advantage that some people tend to forget.

Don’t hesitate to use those 140BT’s. I shot 2 nice Georgia bucks and 4 does this year with my .280AI. I quit using them in early nineties due to their “grenade “ like characteristics but they redesigned them some years ago and are a lot stronger. With my mono loads I have to neck shoot or hit shoulders or they have to be tracked at times. Thanks

[@18wheelsandadozen6shooters5]

Nice job as per usual!!

[@ozark_trapper]

Good results. I like looks of the Federal Terminal Ascent bullet. I have some Accubond LR 7mm 150 and 168gr bullets to try. Had to put everything on hold. Just had neck surgery. I will be down 9 weeks recovering. Before I can start physical therapy. All the 280AI load development on hold. The 175 gr tipped fusion bullets did good. I have been seeing on gunbroker. Pulled Fusion bullets in 7mm 120 gr 140 gr and 150 gr. There suppose to be a good bullet.

I have a Winchester classic stainless 30/06. Its missing its bolt. I have one but mot complete. Im waiting on some parts. IF it HS proper, Ill have 5 30/06 rifles. If it dont... Im HEAVY thinking I need a 280 AI My 7 Mag is twisted 1:10.25". So a 1:8 280 ai would be nice! I have 400+ 175g Nosler LR AccuBond

[@Accuracy1st]

So, how ya liking it so far? I bougth both of mine and the 708 down last night. Going for deer this afternoon

[@alabamareloader]

@@Accuracy1st loving it so far!

[@Michael-Edwards-308]

Please post a link for Heavy Precision. Looks great and I am looking to rebarrel my 270. I am about 1.25 hours from Huntsville.

[@alabamareloader]

@ they’re working on getting their website up and running. Call Mr. Big Guns in Huntsville and they can give you more information. Heavy Precision is located in the same building as them.

[@Accuracy1st]

@ May I ask what cartridge you plan to go with?

[@soldier-mh2gk]

What was your coal for the 140 gr nosler ballistic tip? My rifle also doesn't like the 162gr hornady. But my velocities weren't close on what the box said. My average for the 162gr hornady was 2956. So the 140 accubond should be around 31ish to 32ish in guessing. Also my dropped chart for both bullets. Seems the lighter bullets drops more then the heavy ones. Was this your results with drops.dope. heavy vs light

[@alabamareloader]

@@soldier-mh2gk I’m running it at 3.300”…the Nosler manual recommends 3.330” but that’s the touch point for that bullet in my rifle so I’m only jumping ~.030” loaded at 3.300”.

[@soldier-mh2gk]

What was your velocities with the 140gr nosler bud

[@alabamareloader]

@ 3130-3150 with the 59gr charge. Almost blew a primer at the 62gr charge and it was just one 3300

[@soldier-mh2gk]

I found a box of factory nosler 140gr 280 ackley. 3150 box says. The factory coal is 3.270. My 280 Ackley modified case for 140gr nosler is 3.35 touching the lands. So it's that 80 thou jump? I'm guessing
