FYI - W 296 & H110

[SuperstitionCoues]

I have been gathering information to work up 44 Mag and 357 Mag loads.  Something interesting that I just found out and had confirmed by Hodgdon/Winchester Powders is that H - 110 and W 296 are exactly the same powder, and always have been.  Therefore, the load data between the two are interchangeable. 

Makes things a little easier to find components around town.

They are indeed the same powders but when changing from one to another you should always reduce to starting loads and work up. I have found that it is pointless to weigh individual charges with this powder and it seems to respond better to volume charges than to charges that are individually weighed. I have used this powder exclusively in my 357mag and 357 maximum for over 30 years. It has given me loads that were accurate enough to compete in Hunter's Pistol, hunt white tail out to 50 yards, plink for practice at ranges from 10 to 75 yards and to carry for protection.

some people will argue about this till there blue in the face. Some of them very knowlegable reloaders. Me ive allways thought they were the same. One thing to keep in mind is ive noticed with 110/296 is that there is a little more lot to lot variations in burning speed then with alot of other powders and just because your gun shoots its best with say 20 grains of one lot doesnt mean it will with the next or that pressures safe with one lot will be with the next.

I wish I hadn't read that!!

Now I'm confused, is it ? or isn't it the same powder ?   I have found loads for my 460 with 296 that do not list H110 and visa-versa.  Today I asked a friend who I always considered  " up " on reloading, he says NO, they are not the same.....you can get different pressures form the same weight load.  How do we find out for sure ??

  Personally ,I do not argue with the guys that make the stuff! Almost (make that) ANY powder can and will give you different results from different lots.

I am of the same mind as jhalcott.  I spoke with Hodgdon/Winchester, and H110 and W296 are "...the same powder, always have been..." and "...you can use W296 load data for H110".

That being said, lot to lot variations will also occur.  You should always start conservative and work up..etc., etc., etc.  If you have loads developed for H110 and want to use W296 instead, you might want to work up conservatively again, just to be on the safe side.  It wouldn't hurt, while others may think it a waste of time.  You may find a different accuracy or power curve with the different brand that works better (or worse).  Your choice. 

My interest in the interchangeability between powders came from trying to locate powder in my town.  Load data is just that, data.  Your loads in your gun are something else -  they can hurt you if not done right.  Ultimately the responsibility rests with the loader and user of the ammo.

They are the same. You will get some argument about it though but the powder manufactures will say they are and I guess they know. What to keep in mind though is like was allready posted here. There can be big variations in burning speed between lots of the same powders. 110 has been more notorious then most in this reguard so if your running top end loads allways back off when changing to a jug with a different lot no. This is the main reason why i quit buying powders in one lb jugs for the most part years ago.

Having used both, I think that any minor difference in performance that I may have noted was in my head.  The charges and appearance are VERY similar, but I think that the above is the best advice given.  I would apply this to ANY powder.
