What bullet and cartridge expands past 800m? 1000m?

Best I’ve owned for providing those numbers was the .375 Chey-tac. 1800 fps to nearly 1400 yards with ho-hum 350 gr SMKs.
Dang; it would seem to be that way.
It actually has more energy at 1400 than a creed at the muzzle.For what it's worth my 28 Nosler with 195 EOLs will cling to 1800 fps at 1150 yards. 1398 fpe too. The same rifle with 168 ABLRs meets that criteria at 1050. The 300 Wins that I use 190 ABLRs in work out to 1000 even. STWs with 180 VLDs are also at the 1800 at a grand, as is my 7-300 Win.
.28 Nosler ain't no Peter Pan load. Forget about it..
190gr ATIP @ 3150fps is transitioning the speed barrier at 2400 yards.
Full transition.
Hittin' 1800 fps @ 1300 yards.
Could rattle targets all day behind one of those bad boys and not get tired.
How many rounds can you fire before the groups go past 1 or 2 moa?
40?
20?
I wonder if those long bearing surfaced 195 EOLs heat up the barrel faster then say a .338 Lapua?

I never thought about bearing surface as a heat factor before. Deep down we have to know that shoving about 90 grains down a .284 hole has got to be worse than pushing a similar amount down a .338 bore. My .28 has a carbon fiber barrel, and its hard to direct comparison to a truck axle stainless. I’d rather rotate through rifles than get them screamng hot. Long strings are for .308s.
Yeah. I always thought that bearing surface counts as friction.
A thick barrel and low bearing surface should be ideal.
147 gr M80 ball has a very low bearing surface. My brain thinks of bearing surface in terms of square millimeters.
Less bearing surface and less powder should create less heat and friction.
I wonder which bullet has the least bearing surface with the highest b.c.
and the longest transonic distance. That would technically give you the most consistent groups under heat.
Maybe...155 Grain Berger Hybrid in a .300 RUM bull barrel?
Trillions of combinations.
Anyone have a surface bearing reference chart or grid for all existing bullets?

Since your talking about expansion, I assume your also hunting.
Not one in 20 should be taking these long shots. It's a animal not paper. Burn through a barrel or two ....your probably going to join that few who could take the shot.
Long and sleek bullets in underpowered new calibers or super magnums pushing 100gr of powder and starting out with massive velocity and energy advantages.
Then there's projectile. Frangible, glorified target bullets would open at long distance. Suck at short range. Old school premium hunting bullets with poor bc and work awesome on game at typical ranges. Not really aware of a bullet capable of both.

I totally agree with you. I think that a 220 grain RN .308 going 2200 fps is amazing inside 0-300 yards on ALL North American game.
It's almost as if you cannot have both.
When shooting high volume "target shooting" with a precision platform, I think that certain formulas will resist heating up too badly.
WSSMs and WSMs. .308 based cartridges as well. Low velocity. High B.C.
Lowest weight of powder possible for the intended distance.
So if you want to use a .50 Cal...750 Amax.
Use a .375 Enblr instead.
I always wondered....why does an AK74 melt down faster then an AKM by around 20% +/- in terms of round count. 600-700 vs 900-1000.
Velocity difference? 500 fps? Bore width? Barrel thickness?
All of these things matter.
If barrels wore out from bullet friction, they'd wear out from the muzzle back since obviously the velocity is higher at the muzzle. We know that that simply isn't true; barrels wash out from the breech end where they got nailed with 60-70,000 PSI worth of super-heated gas and un-burnt solids.
Well; plenty of people have loaded down for increased barrel life; so there's that.
