To sustain heat absorption, getting a longer and larger diameter barrel will help. With this, the barrel is prone to bend or deformation. When you fire a round, the barrel length will get hot because of the high energy round and rates of fire. Heat AbsorptionĪs the length increases, the heat decreases. As a bullet exits the longer barrel, it can give maximum accuracy and an effective range of bullets. A longer barrel lengthens the time interval in the chamber the pressure acts on the bullet. The barrel length can also be a contributor to the accuracy of shots but only at a minimum. The gas will push the rounds inside the long barrel for a period enough to fully achieve the powder burn. You can achieve your desired velocity by using high ballistic coefficient bullets or adding the length to your barrel.

ACCURATE 5 OR 7 POWDER FOR 9MM MANUAL
I use a Dillon powder measure for progressive loading and a Lee Perfect Powder Measure for manual drop loads. I have been experimenting with four different pistol powders: Bullseye, Blue Dot, 231 & Unique for four different pistol calibers: 9MM, 10MM, 40 S&W & 45 ACP. 22 Jet, 40-45 grains - Alliant 2400, H110, IMR 4227, W296 The issue for me at this point is how accurately various powders meter. Other powders may work as well or better in your pistol, but these should be suitable to at least get started. For specific powder charges, consult an appropriate reloading manual. My reasoning being that if my experience and their recommendations agree, while the powders so chosen may not be optimum in a given situation or pistol, at least they are unlikely to be disastrous.īecause most retail stores that sell reloading supplied do not carry every brand of powder, I will try to list at least one powder from each of several major powder companies for each cartridge.
ACCURATE 5 OR 7 POWDER FOR 9MM MANUALS
(They may work with lead bullets, but that's not how I use them.) Besides my own 40 years or so as a reloader, I used as source material the major reloading manuals from both bullet and powder manufacturers. 38 Special Wadcutter loads, all of these powder recommendations are for use with jacketed, not lead, bullets. Here are some powders that I can recommend for handgun cartridges that normally give good results with the bullet weights specified.

Then I experiment with different powders (if necessary) to refine the load. I usually test bullets first in any new pistol to find a projectile that it prefers using a powder generally recognized as suitable for that cartridge and bullet weight.

All handguns are different, but normally bullets have a bigger impact on accuracy and performance than powders.
