H335 vs. H380 difference?

Bill Hebert · January 18, 2000, 10:56 AM

I finished my H335 last night and all I had was H380. In checking the powder, they are both spherical and the load data is nearly identical. So the question is - what's the difference between the two? Thanks, Bill.

If you look at the relative burning rates listed in the Hodgdon No.27 Data Manual H335 is listed as number 55 and H380 is listed as number 72. Number 1 being the fastest and number 97 being the slowest burning. Also, in the same manual it describes the H335 powder as originally being a military powder used in the 5.56 NATO cartridge. The H380 powder was originally used to develop the 22-250 cartridge using 38.0grs. with a 52gr. bullet. Hope this helps!

Steve, thanks for the info. I don't have the Hodgen reloading manual. What does it recommend for a 180gr. FMJ in a 30.06 in both the H335 and H380? My manuals have almost the same load data for both powders (and one is so much faster than the other- Hummm??) Thanks for the help. Bill

Bill, the Hodgdon No.27 Data Manual lists the following information for the .30-06 using a 180gr. bullet with an overall cartridge length of 3.300".

H380 starting 48.0grs. 2490fps 39,900CUP
maximum 53.0grs. 2682fps 48,700CUP

H335 starting 42.0grs. 2455fps 41,900CUP
maximum 46.0grs. 2621fps 49,200CUP

Hope this helps!

Steve, thanks for the info. Six grains is a big difference. Looks like since I like Hogden powders above most others, it's time to get the Hogden manual. Thanks again. Bill

You can get the same load data from Hodgdon's website.
