Fiocchi 357 Magnum 142 Grain FMJTC

Fiocchi 357 Magnum 142 Grain Full-Metal-Jacket Truncated-Cone (FMJTC)

👍 Low cost locally, cycles the action on a Coonan 357, with full-power recoil spring, and small-radius firing pin stop. (Update: not 100% actually.)

Lucky Gunner measured 1420 fps out of a 4″ Ruger GP100.

I measured 5 shots at 1216fps, with a high extreme spread of 115fps, out of a 5″ Coonan 357.

I expected my numbers would be closer to their numbers, so I should measure again.

I pulled one round: the bullet was 142.7grains with an exposed lead base, there were 8.3 grains of powder.

Alliant Power Pistol

Alliant Power Pistol “Designed for high performance in semi-automatic pistols”. Manufacturer’s Load DataChemistry and pictures.

Bottom Line: 👍 Lots of fun, good performance.

Pros:

  • Big bright muzzle flash and boom. Lots of fun at the range. Probably the biggest flash you can get in common automatic pistol calibers.
  • Easy to get good performance with this powder.
  • Meters well
  • Decent amount of load data, but mostly for jacketed bullets.

Cons:

  • Big bright muzzle flash and boom. Not as bad as H110, but definitely to levels where it can be distracting to new shooters, and compromise night vision.
  • Largest size it’s sold in is 4 pounds.

+P pressure, not for use in original 45 Colt firearms! Per hodgdonreloading.com this charge is below starting charge (7.5 Titegroup) for a 300 grain Spr JFP for “Ruger, Freedom Arms & T/C Only” level loads,  but above max charge for a 260 grain slug in the original 14kPSI loading.

The article “RCBS 45-270-SAA RCBS 45-270-SAA” from Handloader #246 claims 7.5 grains of titegroup was “maximum” in the 14k PSI range for a 285 grain casting of the 270-RCBS-SAA, and measured it 986 feet per second out of the same model of gun.

Alliant Blue Dot

Alliant Blue Dot is a handgun / shotgun powder designed for magnum loadings.

Bottom Line: 👎 I won’t buy again. But I need to find a substitute first, because I’ve come to like aspects of it.

Manufacturer’s load data.

Pros:

  • Cleans up very easily from powder measures.
  • Decent amount of load data out there, claiming good performance at the high-end loadings
  • Load data claiming very powerful loads in 45 ACP
  • Good performance with heavy bullets in 45ACP
  • Clean burning moderate to powerful 500 Linebaugh results.

Cons:

Notes:

Moderate flash. I’ve heard it’s supposed to have high flash, but in 45 Colt, or 357 Magnum flash is only moderate.
