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

Legit worthy of building a rifle around.

You fhuqking fhuqkers,are hard to fhuqking deal with. Hint.

I've only a trio of 243 Ark's and an (4) in Seex Kreed'. Hint.

None slower than 8"...........

I’ve got the Aero upper on one, a 1-7. I wouldn’t want less. I think the Howa is a 1-7 1/2 and that’s been about as easy as a guy could want.

Both of them make me look like I have a clue.

Sorry, I've been off the site for a while.
Twist is 1:8, 28" barrel. So 85-100gr bullets seem to make sense.

If it's a 1:9 twist you will be somewhat limited in bullets. Rare to see a custom with other than 7 or 7.5 these days. Mine have all been 7 twist which lets me shoot about anything.

With a 9 twist I would be looking at 70 grain Ballistic tips for starters. I will be stunned if you can shoot the 105s with that twist.

He said it’s a 1-8”. I wouldn’t be stunned if a 1-9” 243AI will stabilize a 105. My old 243 barrel would shot the 105 amax and so will my brothers 6mm Remington. Both factory barrels and I don’t think they were 1-9”? I could be wrong but think they’re something like 9 1/4 maybe? Anyway he said he has a1-8” with a 28” barrel so he should be fine with any 105/8’s I can think of.

A true 9" will certainly stabilize 105's,in said chambering. Big Green spouts were 9" and small change,which also stabilizes same. Hint..................

I would be more concerned with a my 28” barrel on a gun I’m hunting with. First thing I would do is have 5-6 inches cut off.

I take that back. I’d work up a load and record velocity as it was cut down. I don’t know if I’d really do it or not but it would be interesting to see first hand results on velocity loss per inch or two cut.

Agreed. This is out of my sons first rifle using the AMaxs about 10+ years ago. It is one of them youth M700 ADLs.



Not it’s finest showing but he cut his teeth shooting a pile of them at rocks and water jugs. Even with the crappy trigger and 2x7 Leupold he did fine.



I promised I wouldn’t make him suffer with it like that and will get it fixed up for him

Well you could replace the scope rings trigger barrel and stock. Heck it would even kill stuff just as good as it does now….grin.

It’ll catch an update. That little stock is a little short for us. Maybe a Trigger Tedh, along with a scope. He might as well have it well set up. He’s done a bunch of killing with that cheap little rifle.

That will be cool. My first and second rifles were a 700 and a 7. One became a 6creed and the other a 708. I like taking childhood things or sentimental rifles like that and fixing them up the way I want them now. I know some times it might make more sense to just get a custom action but I like my old hand me down stuff too. I’m sure your son will be excited to see what you come up with.

Not all 105s are created equal
Some of my boxes state 1-8 twist right on the box

denise,

Your sheer and utter fhuqking CLUELESSNESS,never disappoints. Hint.

Projectile Stability is a function of gross RPM,which is the melding of forward momentum,WITH twist rate. Boolit makers would help Dumbfhuqkers like you,if they stated a minimum gross RPM,in a given atmosphere,as a stability indicator. Until then,you get to guess,as you "shoot" your mouth and Imagination,while Pretending. Hint.

For clarity,the 243AI accelerates all 105's at a nice clip and now even you "know". Hint.

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

Thanks Kaleb. It’s a work in progress. Kids an active duty Marine so just getting him some hunt time yearly is a challenge. It’s cool to see him light up when he gets cool guns/gear when he ventures home.

Velocity only helps so much. Twist rate much more important than velocity.
Too bad your so single minded and simple

denise,

Describe "your" 1-9" 243AI,that "won't" stabilize 105's,as per the BEST of your Imagination and Pretend...you "lucky" kchunt. Hint. Congratulations?!?

Pardon 3rd from bottom,being one of said configuration and more than a touch happy with 105 Hornie's('Max/HPBT),108 RLD M's and 105 Booger(HighBirds). Hint.



Pardon my simply shooting it all,as you set astride your Couchbound Kchunt and guess aloud. Not that your Magnificent STUPIDITY,ain't funnier than fhuqk. Hint.

Gals who "know" and "do" as "much" as you,will ALWAYS be best served by asking questions,rather than giving "answers". Read that again. Now one more time. Hint.

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

Never seen a 9 twist that would not stabilize a 105 BTHP, and I've had plenty to experiment with.

Both muzzle velocity and twist rate are factors in determining gyroscopic stability, but stability depends quadratically on twist rate and on the cubed root of muzzle velocity. For example, a change in twist rate going from 1:9” to 1:10” is equivalent to going from 3000 fps MV to ~1600 fps.

That being said, according to the Miller stability model a true 9” twist will stabilize even a Berger 105 Hybrid at 3000 fps, at sea level, down to below freezing temps. I prefer to stay in the super-stable regime (7” twist) for BC reasons, but 9” will at least stabilize it in most air density conditions. The 105 HPBT and AM are shorter and easier to stabilize than the 105 Hybrid. The model shows that a 9” twist stabilizes the 105 HPBT at sea level down to below -40 F.

Most of my experience is above sea level, but a 9.125” twist has always stabilized the 105 HPBT/AM down to about -40 F for me.

In a modest length 243AI(22") shown,I tend to whistle 105's at 3250fps. However in FULL disclosure,the pic was BELOW sealevel,due the tide. My apologies for the confusion. Hint.
