I was reading up on the Hodgdon website on 357 magnum loads. I noticed that all data on H110 and Win. 296 is exactly the same. Are these two powders the same,just packaged different?

Yes. It's like that with several other powders, HP-38/Win231 being one of them.

St Marks Powder (Gen'l Dynamics) makes the same ball powder -- which Hodgdon labels H110, and Winchester Powder (which Hodgdon now owns) labels it W296

Exact same powder out of the exact same barrel.
The only difference is standard lot-to-lot variation.

Currently:
H-110 is the same as W-296
HP-38 is the same as W-231
HS-6 is the same as W-540 (discontinued)
H-414 is the same as W-760

However this has not always been the case.
Winchester powder was made by Winchester at thier St. Marks FL facility beginning in 1969.

In 1998, Winchester got out of the powder manufacturing business all together, and St. Marks Powder, Inc. became a seperate company.

In 2006 Winchester divested itself of powder packaging & distrubution.
And Hodgdon took over the packaging & distrubution.

From that point foreward, it all comes out of the same shipping containers and is packaged by Hodgdon.
The powder magazine, packaging, and manufacturing facilities are located in Herington, Kansas. Additional magazine space is located at a closed military air base, (Forbes Field) leased from the City of Topeka, Kansas.

So, if you have older powder, or older data, they were not the same prior to 2006.

RCModel is right. The old H110 was dirty as heck and the 296 was cleaner. they also gave slightly different results in my .44 mag and .44 Auto Mag. H110 always was slightly more accurate in my loads. 296 produced higher velocities for me.
I bought several large containers of 296 just before WW went out of the powder business.

H-110 started out as surplus .30 Carbine powder left over from WWII.

Bruce Hodgdon got his start in business selling surplus military powder like 4895, 4831, H-110, etc. following WWII.

He started out selling 150-pound kegs of 4895 powder for $30.00 each plus freight through little adds in the American Rifleman!
