A caliber with more punch and weight that .25, better bc than .30, more fps than .30 and super accurate and energy keeper at long distance to assure killing power and accuracy.
N/A I think we need a new caliber among .25 and .30 for hunting and Target shooting
- Thread starter Emu
- Start date
Guns made for said caliber that would accept a super long slug. Maybe a 4-6 s nose shape with a rebated boat tail. Something not limited to short chunky slugs and have an emphasis on max bc

There are already 50-60g boattail .25 slugs and also a .257. It is already here, you just need to find a gun for it. Lol

I think y'all just described the characteristics of the Air Force guns.
You can get a .257 or .308. They are powder burner diameters and shoot longer slugs at higher BC's with high very high FPE. The only downfalls are they are not regulated and you have to single load. I really wish AF would update them...

One of my pet bores. In reality I think 257 is the real answer to most elr problems but 284 may have an advantage in 1 specific bc/trajectory application if a gun were built from a projectile up.

6.5mm (0.264). Since I got my first 6.5X55, I've loved that cal...which is why I went with .25cal.
I wonder if PCP power levels would support faster twist rates...like 1:10...

Good with what is available. We will get like powder burners with 100000000 choices that are basically the same thing.

For FX, building a Leopard for that caliber should be REALLY easy.
For NSA and AVS to make the appropriate slugs form that caliber should be cherry picking.
Leopard is superb in accuracy. It just need a perfect caliber to get to the pinnacle.

A few years back I was looking for this exact thing. I ended up on the .257 bandwagon. I built a converted disco with a TJ’s 1:14 liner to start but the shot count was low and was single load. I then moved into converting a Winchester 70-35 to the .257 caliber. This was and is much better, after modifying the magazines for the smaller cal. I’m able to fit the 257420 bullets. I get one full mag of 7 shots on a 230bar fill on high power 150 fpe and two full mags when tuned down to 120 fpe.
I’ve come to the conclusion that the .257 is about as close as we air gunners are going to get to the perfect balance of power and BC . If I were to go down this road again, I’d now start with a bulldog ( weren’t available at the time) tune it for the 257420 bullets and be happy.
