Federal's newish .30 Super, aka a 'spicier' 7.65x20mm Longue

[the Schwartz]

I have to admit that I am kinda, sorta surprised to see this...



A 0.3125''-caliber 100-grain FMJ (AE30SCA) and a 115-grain HST JHP (P30HST1S) at 1,250 fps that expands to 0.53'' and penetrates to a depth of 15.5 inches in 10% ordnance gelatin. Looks to be loaded somewhat warmer than the old 7.65x20mm Longue. Not sure what 'need' it addresses though since it essentially duplicates what we already have in many of the service calibers.

It's not exactly ''compact'' either with an OAL of 1.169'', the same as the 9mm Luger.



The .30 Super 100-grain FMJ @ 1,250 fps promises to offer tremendous penetration in the 31 - 34 inch range unless it yaws and overturns.

What are the P-F collective's thoughts on this latest offering from Federal?

Is the benefit higher magazine capacity in a narrower package?

Seems smart if they can monopolize the market for something like that.

Discussing terminal ballistics here, not the platforms that fire the cartridge.

Ballistically it is not going to offer anything new or of significant difference. It will work a comp or ported barrel likely better and it may have minuscule better ballistic co efficiency with a longish bullet and smaller frontal area. Otherwise anything it does ballistically is already available.

However you can't discuss a cartridge without discussing the launching platform it is fired from and in this case that makes or breaks this cartridge when capacity/size efficiency is considered with performance.

What happens inside the firearm/platform is interior ballistics.

The topic of this thread is terminal ballistics of the .30 Super Carry; that is, what happens at the ''receiving end'' of things.

There is a difference.

Based upon my experience shooting hot loaded .32H&R Mags and .32-20s a flat-nosed FMJ with meplat greater than half of bullet diameter will not "flip" but should produce straight-through penetration if adequately stable. A twist of rifling of 20 inches per turn, as used in the .30 US Carbine and .32-20 rifles will be fine with 100-115 grain bullets at this velocity level.

Might be interesting to see how this cartridge would perform with 85-grain XTPs at about 1300-1350 fps, approximating .30 Mauser.

As discussed in the other thread, ballistically it's pretty much .32 H&R, so there isn't very much new to say about what happens once the bullet passes the crown. They're loading it with Gold Dots, including one that has been out of production for years. But not quite - they made it .313 instead of .312, so they can fail harder.

Always happy to defer to your greater knowledge on the matter!

I'd also wondered if something like this would have its center of pressure located aft of its center of gravity so that it would go ''straight line''.

Certainly, the shape of the projectile nose (meplat) may also act to reduce instability, particularly at higher impact velocities, where the projectile-target material interaction is mainly along the projectile nose.

Have they published any data on performance through barriers? I wonder if the sectional density can make up for the light weight when going through things like laminated glass and sheet metal.
