What is Hodgdon H4350 good for?
H4350 is ideal in the WSM family of calibers (270, 7mm, 30, 325) and is also the standard in such cartridges as the 243 Winchester, 6mm Remington, 270 Winchester, 338 Winchester Magnum and many more. For magnums with light- to moderate-weight bullets, it can’t be beat!
What is the most temperature stable rifle powder?
Powder Heat Sensitivity Comparison Test The testers measured the velocity of the powders over a wide temperature range, from 25° F to 140° F. Hodgdon H4350 proved to be the most temp stable of the four powders tested.
What is temperature sensitivity factor?
Temperature Sensitivity Factor: Accounts for changes in muzzle velocity with changes in temperature. Temperature Sensitivity Coefficient is the slope of this line.
Is accurate powder temperature sensitive?
Most of our powders are not insensitive, and will show some effect at hot and cold temperatures. However, we test at -40F and +125F and the deviation in most cases are ca 3% to 5% at these extreme levels. Therefore most shooters do not notice much difference under normal practical hunting conditions.
Who makes Hodgdon H4350?
The ultra-popular H4198, H4895, Varget, H4350, and H4831 family of powders are produced by ADI in Australia**. So Hodgdon can’t ship more Varget or H4350 in the USA unless Hodgdon can get more from Australia.
Is Hodgdon benchmark an extreme powder?
As the name implies, this Extreme Extruded propellant was developed for precision cartridges. As such, it is ideally suited for benchrest and small varmint cartridges like the 6mm PPC, 22 PPC, 6mm BR, 223 Rem. and 222 Rem.
Are Alliant Powder temperature sensitivity?
Until recently, Alliant’s Reloder line has not provided competitive temperature stability characteristics. That’s changed with Reloder powders: 16, 23 and 26. They are advertised as stable across a vast spread of temperatures. Real-world extreme-temperature testing tells the true story.
How do you calculate temperature sensitivity?
More simply stated, we can calculate the sensitivity of a resistance thermometer by multiplying the resistance of the RTD at the reference temperature R0 (i.e. its calibration temperature) by the Temperature Coefficient of Resistance (TCR, or alpha value) as follows: Sensitivity = KRTD = R0 * α.
What powders are not temperature sensitive?
Hodgdon Varget was the second least temperature sensitive powder in this test, with 46 fps of variance in muzzle velocity between temperatures of 25° F and 140° F. IMR 4166 performed very similar to Varget, and proved to be fairly insensitive to large swings in temperature.
What reloading powders are not temperature sensitive?
Is accurate 2520 a ball powder?
Accurate 2520 is a medium burning, double-base, spherical rifle propellant designed around the 308 Winchester. 2520 is our “Camp Perry” powder and is extremely popular with many service shooters. 2520 also performs extremely well in 223 Remington with heavy match bullets (62 to 80 grain).
What is the difference between Hodgdon’s H4350 and IMR 4451?
IMR 4451 – IMR already had powder named “IMR 4350” with a similar burn rate to Hodgdon’s H4350, but it lacked temperature stability. So they designed IMR 4451 to burn in the same cartridges AND be more temperature stable. Some shooters have told me IMR 4451 allowed them to squeeze a little more velocity out of their rifles, compared to H4350.
What is H4350 powder used for?
H4350 H4350 is an extruded propellant in our Extreme series that has been one of our most popular powders with shooters for decades. During that time, Hodgdon has modernized H4350 by shortening the grains for improved metering and making it insensitive to hot and cold temperatures.
Why are Hodgdon’s extreme powders better at 125°?
That’s because the “Hodgdon’s Extreme powders perform just as well at 125° as they do at 0°. Using an exclusive extrusion process and exacting quality standards, Hodgdon has created a line of propellants that performs better at hot and cold temperatures than any other powder on the market.”
