by Hodgdon
Product Overview
Midsouth is proud to offer the Hodgdon H4350 Smokeless Powder 8 Lbs. Hodgdon H4350 Smokeless Powder is an extruded stick type powder that works exceptionally well in any environment, hot or cold. Hodgdon has done extensive testing to ensure that the Hodgdon H4350 8 Lbs has as little deviation as possible.
The H4350 Reloading Powder is quickly ignited and a very fast burning, clean powder. Hodgdon H4350 Smokeless Powder ensures better accuracy on the range a good clean kill in the field. Hodgdon H4350 8 Lbs is the best choice for many WSM calibers, especially .270, 7mm, 30, 325 and standard power cartridges such as .243, 6mm Rem, 270 Win, 338 Win Magnum and others. The 8lbs size makes using H4350 Reloading Powder not only the most accurate choice, but also economical.
Hodgdon H4350 Extreme Extruded propellant is a burning speed that has been known to shooters for decades. During that time, Hodgdon has modernized H4350 by shortening the grains for improved metering and making it insensitive to hot/cold temperatures. H4350 is ideal in the WSM family of calibers (270, 7mm, 30, 325). H4350 is 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!
United States powder manufacturers resumed powder sales of one-pound (454 gram) canisters after observing Hodgdon’s successful sales to handloaders. DuPont resumed retail distribution of their pre-war nitrocellulose Improved Military Rifle (IMR) series; and Hercules Powder Company resumed production of six of their pre-war double-base powders. Hodgdon Powder Company began using an H-prefix to differentiate powders distributed by Hodgdon from competitors. Surplus Vulcan cannon spherical powder was distributed as H870 beginning in 1959.8
All of the surplus BL type C had been sold by 1961. Olin Corporation had manufactured the powder as 846, and continued production for loading 7.62×51mm NATO cartridges.3 Hodgdon began marketing post-war production as spherical BL-C lot no. 2, or BL-C(2). Olin began retail distribution of Winchester-Western ball powders for pistol and shotgun loading in 1960; and Winchester-Western rifle ball powders followed in 1968.6 Hodgdon distributed spherical powders HS-5 and HS-6 for shotguns and H110, H335, H380, H414, and H450 for rifles.9
DuPont added IMR 4895 to their retail distribution line in 1962, and added IMR 4831 in 1973 when supplies of surplus H4831 were exhausted.10 Hodgdon then acquired newly manufactured H4831 from Nobel Enterprises in Scotland. The Nobel formulations offer similar ballistic performance, but substitute centralite deterrent coatings for dinitrotoluene used in United States formulations.6 Handloaders were advised H-prefix powders were not the same as IMR-prefix powders of the same number.4 Hodgdon distributed H4198 and H4227 similar to IMR powders distributed by DuPont.9
Hodgdon’s product line includes Pyrodex and Triple Seven, which are modern substitutes for black powder and intended for use in muzzleloaders and certain antique firearms. Consequences of black powder’s easy ignition by sparks or static electricity make manufacture and storage hazardous. The sole factory of the United States’ largest 20th-century black powder manufacturer was closed by an accidental explosion as 1970 legislation established new regulations discouraging merchants from stocking black powder for sale. Future historical re-enactments with replica firearms appeared doubtful until Hodgdon introduced black powder substitute Pyrodex in 1975 with black powder combustion characteristics and smokeless powder safety.
United States powder manufacturers had discontinued production of sporting ammunition during World War II; and after the war attempted to exercise greater product safety control by emphasizing sales of loaded ammunition rather than resuming production of handloading components.5 A common approach to product safety involved offering ammunition safe for use in the oldest or weakest firearm chambered for that cartridge. Owners of stronger firearms found and experimented with Hodgdon’s previously unknown powders to achieve ballistics superior to available factory ammunition for older cartridges like the 7.92×57mm Mauser.6 Long-range shooters found 4831 was superior to previously available powders for high-capacity bottle-necked cases.

In reference to the other post on temperature sensitivity with this powder, I too have seen more than advertised velocity variation with H-4350. My load for a Tikka 243 Win was 100 gr Nosler partition, Win LR primer, H-4350. Using the same cases, powder, primers etc. I left the gun and shells outside over night. At 30 degrees it gave an average velocity of 2940 fps. Leaving gun and shells inside at 70 degrees gave an average of 2980 fps. Leaving gun and shells at 110 degrees for several hours still gave an average of 2980 fps. This is good, better than other brands of powders, mainly at 110 degrees. The fired primers looked about the same in all tests, ie the ones at 110 degrees were flattened the same as at 30 degrees. I called Hodgdon and asked Mike a tech. Interestingly enough he admitted that their tests are not done to represent the real world. They only cool or heat the loaded shell, not the gun. He said this truly tested the powder. My opinion is that may not be true. Having a gun at room temperature and the shells at 10 degrees or 100 degrees could give misleading results. The difference in the gun’s temperature may compensate for variation in the powder. What hunters and target shooters are interested in are real world results. In this regard they may have failed a bit (especially in their advertising.) Another similar test that I ran in a 7mm WSM with H-1000 powder showed almost no variation from 110 degrees down to 10 degrees. It was a compressed load with 160 gr Nosler Partition. I still maintain the Extreme powders are the best for velocity/pressure variation, especially at the high end of usable temperatures.

My first time using this powder, I just looked at the load data for a 120gr TTSX and picked 42.1 gr of H4350. I put three shots into .271 inch. I think I found a new deer load for my Creedmoor. About 2800fps out of the barrel of my Savage Axis 2 with the heavy barrel. Mild recoil and it just seems so easy to shoot. Lookout whitetails. Thanks for having it in stock Midway
