243 handloading

The LoadData website doesn't show any data for a 130 grain bullet in .243 Winchester; highest I found there was a 115 grain Berger. Nosler makes a 115 grain bullet, too.

To fit into a standard chamber: A 130grn bullet made for 243win would likely have to be a short ogive, long shank design, else it won’t fit in the mag box or throat. It would eat up a lot of powder capacity, and assuredly set the bullet base below the shoulder/body junction. Being such a long bullet, it’d also likely fail to stabilize in standard twist barrels; consider the 105-115’s already struggle.

So it’d be possible, but it wouldn’t be great. A custom chamber and custom barrel twist would be required to use a proper long ogive, high BC bullet.
 
Given a custom throat, single shot loading, and a fast 7 twist, it LOOKS like it could work in 243win or 6 creed. I don’t think it would work in a standard chamber without seating the bullet considerably below the shoulder/body junction. Which is to say it could work, but wouldn’t be optimal.

Just doing some math, correcting a BC for a 130 based on scaled sectional density, estimating approximate velocity based on energy potential, using a bullet length from a custom bullet maker who made some 6mm 130grn bullets a few years ago on LRH forum (meant for a big case wildcat like the Allen or Gibbs mags), and using Berger’s stability calculator, it looks like a 7 twist in front of a 6 creed or 243win case should be able to stabilize it. Looks like...

Based on my experience with 105 ELD’s and 108 Hybrids, I don’t think a standard 6 creed barrel will chamber a 130grn bullet without being seated very deep in the case, which would steal some speed, but still might get to stability.

Now... if the objective is a high BC meant for long range hunting, then we’re talking about a slow enough speed, I don’t think it’ll be worth it. I ran numbers out, looks like it would fall subsonic at 1490yrds, with 979” drop. Whereas my 105 Hybrid load hangs on to 1520yrds, with only 828” of drop. .330 at 2600 vs .275 at 3035.
 
You’re going the wrong direction.
What you seek, is a Barnes Tripple Shock X monolithic bullet.
It can be pushed to high velocities, is potentially extremely accurate, doesn’t break up, and penetrates deeply, VERY destructive to soft tissue. But, needs 2,000+ impact velocity to reliably expand.

The 85gr TSX is very popular in W.Georgia in the .243. Just EXPENSIVE.

However, most “locked” core bullets (Interlocks, Coreloks), or bonded bullets (InterBond, AccuBond,) or Partition type bullets work quite well.

Shot placement X-3!

Yup, the 243win lives on speed. Plugging it with an overweight slug takes away that advantage. Punch a 95 VLD Hunting bullet into the pumphouse of a whitetail at 100yrds and in and you’ll watch a 20yrd wobble as if on stilts before it goes down. The TTSX will deliver as well, just costs a lot more than it should for a simple whitetail hunt.
 
100 gr prohunter, 95 gr fusions, 95 gr sst if you want to splode the soft bits are the top ones that come to mind for up close .243, and that's only cuz I'm not letting go of my round noses.

Also 100 gamekings Speer used to produce a 105 round nose that would work well also. The 105 was quite accurate in my 243.
 
I'm looking for accuracy at Max 80 yards...

I can't possibly see how a regular loading of this cartridge couldn't do this. Branch or no.
But a round nose may be better at it. Pointier bullets may deflect more.

Brush guns are for the "walking through it" part...
 
I think the OP has had the same kind of failures I’ve experienced and witnessed.
I’ve had numerous failures of the .243 with cup and core bullets at distances under 100yds with the .243.
He’s looking for something that hits hard, but won’t fail to penetrate sufficiently.

The monolithic bullets meet that criteria. The .243 is the poster child for either close in blow ups, and long range failure to expand.
Otherwise, excellent within the 75-250yd envelope.

We've been picky with bullet selection for this reason and have yet to experience failures one way or the other, we've exited the full length of a muley at 30 yds, and still had proper expansion at 500, with matching penetration. A mono generally is less dramatic than desired, (I run monos on yotes) the wound is less impressive, you DO get penetration with high speeds, but lose overall distance for velocity window. I use the exact bullets I listed plus a couple I didn't (need to enlarge sample size) for friends and family, not all cup and cores are created equal. If we truly want a magic bullet, it'll be either an a-frame or scirocco2. The window is more forgiving on them than their nosler counter parts.
To clarify, the sst if treated like what it is, is phenomenal at close range (detonation) with proper placement.....for this that means broadside behind the shoulder..... the pro hunter is plenty tougher, we launch it at 2920 from a 20" tube and don't get overly nervous about "the perfect shot". Would I do this with a speer? Nope. Hornady? Maybe, probably not. Bonded bullets? Yes. Partition types? Yes. But I prefer the damage inflicted by a lead base, as coppers either shed petals up close (early Barnes), don't impart enough shock, or don't open enough, fast enough, farther away to become an automatic standard.
