True Blue

Ramshot True Blue is a modern pistol powder suitable for moderate to heavy loads in many calibers.

Bottom line: 👍 Meters superlatively, nearly universal application in handguns, low flash.

Pros:

  • Very fine spherical granules (.0083 to .0165 inches in diameter) meter well
  • Low spreads and standard deviations when fired
  • Can be used in many different cartridges.
  • Low flash. Even indoors with 454 Casull rounds going 1400fps

Cons:

  • Can be a bit messy, because the fine grains get everywhere.
  • Despite the fine spherical shape giving very repeatable throws, there is an occasional “hangup” feel in the Redding 3BR — as if granules sometimes get cut.

Density (per manufacturer) 15.046 grains/cc ±3.6%; But Lee dipper chart says 14.6 grains/cc

SAECO 58

The SAECO #58, is a .451 caliber 215gr SWC with a huge meaplate. It was made for bowling-pin shooting from a 1911. The huge meaplate was thought to grab pins better. It’s interesting to me, because it’s about the flattest thing that feeds well. In paper, it does not cut like a SWC. The nose cuts clean holes, but unfortunately they’re surrounded by a “torn” halo (like a round-nose leaves) from the more-rounded shoulder. Load data is surprisingly potent! The slug is only 7% lighter than the classic 230 grain ball, but it’s driven about 100fps faster.

I had great consistency with True Blue.

Montana Bullet Works sells high quality cast SAECO #58 bullets, nominal Brinell 15 hardness. Missouri Bullet Co. has a coated version called the .45 Express-Grooveless, nominal Brinell 20 hardness.

Lyman Cast Bullet Handbook 4th Ed. says 1.185″ OAL, Remington cases and #2 1/2 primer, bullets sized to 0.451″

START 6.6 grains PowerPistol 880fps @ 13,800 CUP

MAX 7.3 grains PowerPistol 966fps @ 17,600 CUP

START 6.9 grains True Blue 875fps @ 14,200 CUP

MAX 7.6 grains True Blue 955fps @ 18,000 CUP (most accurate load tested)

I did: Brass Guys (full length resized and mixed) brass, but fired were Winchester headstamp. Rem 2 1/2 primer. .45 Express bullet sized .452. #45.5≈6.6gr Power Pistol. Actual OAL varied from 1.1860 to 1.190″. 5″ Les Baer 1911, or 4.25″ 1911 (Ed Brown Kobra Carry).

LabRadar Series: S120 (5″ 1911), steel target at ~25 yards, except last 3 where the target was 100 yards.

Velocity: 901 feet per second

Spread: 46 = 923-877=46

StdDev: 12.88 (17x)

LabRadar Series: S207 (4.25″ 1911), 100 yard target. Very noticeable muzzle flash at night.

Velocity: 864 feet per second

Spread: 39 = 886 – 847

StdDev: 13.84 (10x)

Using the Montana Bullet Works slug, and totally unsorted “Brass Guys” brass I got: (NOTE loaded and shot on different day):

LabRadar Series: S38 (5″ 1911)

Velocity: 904

Spread: 47 = 934-887

StdDev: 15.64 (7x)

Using the same .45 Express bullet as above, Nickle plated Winchester brass (from Southern Belle Brass) and 7.0 grains of True Blue:

LabRadar Series: S129 (5″ 1911)

Velocity: 900 feet per second

Spread: 26 = 911-885

StdDev: 7.29 (10x)

LabRadar Series: S208 (4.25″ 1911)

Velocity: 880 avg (876, 890, 872, 883)

Spread: 18 = 890 – 872

StdDev: 8.13 (4x)

Some muzzle flash with the shorter 1911 at night.
