I use H110. I believe Win 296 and H110 are the same or very similar powder.

My load:

110 gr FMJ projectile (Magtech, Armscor, LC pulled)
15.0 gr H110
Prvi Partizan or Aguila case
Fed SR primer
OAL: 1.675"
1940 FPS @ 55F

Vastly superior accuracy can be found by climbing up from 14.3 gr during development. Some lighter loads will fail to cycle well. Start here and work up to 15.0 gr. This is most competitive shooter's load. Your carbine will likely be picky to one particular narrow velocity range. Go up in 0.2 gr increments until you find the sweet spot. Temperature will affect velocity with these powders so be mindful of that.

15 gr ww296 is the military load for the carbine. As HammonJE stated H110 is supposed to be identical.

Default Ww296

I load 15 grain sof 296 behind a 110 grain fmj using a CCI41 military primer. Equivalent to the military ball load. Accuracy is excellent. Meters well in apowder measure.

Ditto: H110, or Win. 296 either will work. (Follow Manual)

Ditto on WW296 with 110 gr FMJ or RNSP. What hammonje says about temperature affecting velocity is true and worth remembering. Can't speak to very low temperatures, but here in Phoenix, my WW296 load is significantly faster at 110 degrees than it is at 70. I was surprised at how much.

Default I would select a powder that you can use with other calibers

For instance if you load .357s, 2400 might be a good choice. Look into that aspect of it. I have used about 4 different powders and honestly there hasn't been a lot of difference in performance. The carbine is a very forgiving cartridge. The 30-06 is the polar opposite in this regard as the M1 is very powder sensitive.

The most important issue with the carbine is case length. Too short, OK; too long can be big trouble.

I love these kind of questions and discussions because there is so many facets to reloading.

First, I have seen listings for reloading for each of the powders you listed. The most common used seem to be either W296/H110 and 2400. There are pluses and minuses for each. Yes, W296 and H110 are the same powder. They are just different lots. Winchester subcontracts out their powder production to Hodgdon. In fact, Hodgdon also produces IMR powder.


As you mention you have loadbooks already, sounds like you have reloaded before. I would follow your load data and experiment as to what you want. I used 2400 for over 20 years for 30 carbine, but I am a recent convert to the W296/H110 crowd. Cleaner, hotter and meters better for measuring.

As far as different speeds at different temperatures, that is more a function of exterior ballistics (air density) than the chemical reaction of the powder.

Don't forget that CMP forum has a reloading section - lots of chatter on powders and carbine reloading there.

Hope that helps...

hmm I may be blind but I did not see a reloading section. Have to go look see. I reload for my Garand and have come to like Varget over all others I have tried.
I cant afford to shoot both unless I reload. I am buying enough for 500 rounds for now. That should keep me shooting for some time as the Carbine will see limitted use. I just cant put the garand down.

Reloading is a sub-section after "Ask Each Other."
