      I’d like to get a tread started, that would be a great help to me and I’m sure to other reloaders out there.

      Mainly with Hodgdon’s buying up other companies and renaming powders it’s causing a lot of confusion, it would be nice to have a list of powders that have changed names or have been rebranded. It would be nice if the final list where made into a sticky for future reference, the only problem is that the list would have to be a definite “I know for a fact that this powder is the same as that powder” other wise we would be giving bad information.

      I know for a fact that H110 and Win 296 are the same.
      Win 231 and HP 38 are the same.

      I’m trying to load with Hodgdon Hi skor 800x now and as far as I can work out it is now the same as IMR Hi Skor 800x. Is this correct?

      I’m also working with IMR 4227 and as far as I can find out, it is now the same as Hodgdon 4227. Is this correct?

      Don’t know about the 800x, but according to what I’ve been able to find out, both 4227 powders are the same. Also, according to Hodgdon H414 and Winchester 760 are the same.

      IMR 4227 made in Canada(OLD STOCK) is different than the IMR 4227 that is curently up for sale

      IMR 4227 that is currently up for sale is the same as H4227 (Not made in Canada) and load data is different

      I found this on the S&W forum, does anyone agree with it?

      My experience with Hodgdon powders is that they are approximately one grain slower than the IMR powders of the same designation. Occasionally one can go two grains more with the Hodgdon, but not normally.

      And if you look at load data for a particular projectile/cartridge and both 296 and H110 are listed, you will see virtually no difference in velocity OR pressure for the same charge weight. This to me indicates that if they are not one and the same they are so close as to be indistinguishable from each other.

      I hope this helps…

      H4227 and IMR4227 are not the same powders but W296/H110 are identical.

      From everything I’ve read H4227 was switched over to IMR4227 and even though the name IMR4227 is still alive the original IMR4227 powder is no more. The current IMR4227 is really H4227 relabeled.

      The two 4198 powders are not the same either although very close.

      Just for future reference:
      W231 = HP-38
      W296 = H110
      W540 = HS-6
      W571 = HS-7 (both discontinued)
      W760 = H414
      WAP = Silhouette
