Home Forums Hunting & Shooting Custom Rifles & Wildcats 243 Ackley Improved Pet Loads

Just picked up a 243 Ackley Improved. Plans are to use it for Coyote hunting and target shoot with it. Anyone out there have any pet loads you can share? It looks like 6mm Remington is closer for load data than 243 Win in the manuals when comparing case capacities. Thanks!

What bullet you planning on ?

I've not bought any bullets yet but am looking at the 87gr V-Max and the 108gr ELD Hornadys for target. I'm not stuck on any bullet but have had a lot of success with Sierra Match Kings in 30 cal 308, 30-06, and 300 RUM and ELDs in 6.5 in my 264 WM.

105s with cases full of RL26.

Where's Stick when you need him?

This was one of his go-to's before he caught the gay (Kreedmire)

About time he contributes something useful around here. . . .

You better divulge the twist of said rifle so you can receive a proper tongue-lashing (you can thank me later)

What twist is your 243AI?

Not too "surprising",that Whiners will always find reason(s) to Whine. Hint.

I shoot a "few" chambering in said bore size and often on the same day. Hint.




The 243AI dupes 6mm Rem case capacity and is a vastly superior mechanical design. Like capacity,uses like data,arranges like performance,at like barrel length and like pressure. I want a Hornie 105 HPBT and '17,unless RPM and COAL grant opportunity for .6xx BC's. Hint..................

I summoned the Great Swami, yet no pet loads were revealed - I can feel the OP's disappointment . . .

Rifle particulars haven't been cited and not even I,can load for Imaginary Rifles...though others "can". Hint.

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

I've had several 243 Ackleys and love 'em.

In mine, with <90 gr. bullet weights and 10 twisted barrels, H414, WW760 (same/same powder, now) and Accurate 2700 gave best results. Primers were Fed 210s, either standard or match giving the same results even in sub zero weather.

If the back end of the teamer has been spec'd to work with Lapua 243 cases, life will really be good for you. F-forming with a top end charge of fast-ish powder for the standard 243W, the bullets firmly into the lands (.020 past the 'just touching' point) and cases very lightly oiled with 3-In-1 or something similar will give you great cases on the first firing.

For load data with a F-formed case, start with top end loads for the standard 243W or, as 'Stick mentioned, hop to the 6MM Remington standard case and go from there.

Good shootin'. -Al

Oh geez, THIS ding dong again.....Hint, hint.....haha
Rifle is a Hart 2A action, RW Hart rifle. It's due to arrive Thursday. Have to check twist on it, but I believe it's 1:9.

Thanks for the constructive advice!

Fhuqktard,

THAT was awesome and I appreciate you doing your fhuqking best! Hint.

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

Stick and Al both gave great advice if it will apply to your rifle.


I've had several 243 AIs and have a soft spot for the chambering.

I've had one 1 in 9 and 2 one in 8 twists. My favorite load in all was a 105 hornady, either amax or hpbt with 44 grains of h4350. RL 17 also is wonderful.

Mine were throated to fit the 105s in the mag box of a remington with room to spare, something to consider. If you have too long a throat going aics is the easiest route .

6mm rem data is a great starting point for formed cases

If you have the twist, and the powder, this is a really good combo.

48 grains in formed Lapua cases scoots at 3,128 fps in my 21" PacNor.

Never heard of it. IMR? Hint..............

[bleep]

I'm going to try Staball in mine when I knock the cobwebs off of it. Can't stop shooting the 6br and 6 creed long enough to mess with mine

Admittedly,I'm SWEET on the 270 and 6 PPC AFI both. Hint..............

It’s awesome isn’t it? Glad I bought what I did when I did.

It’s far too much fun.

The 6 ARC is an animal in an AR in my book. Been spreading the word as much as people will listen. As a straight up no horseshit deal it’s hard to go wrong.

The 6 creed ain’t a slouch either.
