I am currently testing some H4895 in my .22/250.
I see that IMR also make a 4895 powder, are these 2 powders the same or do they share the same ballistic properties ?
Is there any advantage over one or the other.
I ask this as IMR powders are hard to get in my part of the world.
Also has anyone had good results with H4895 in the .22/250 ?
Thanks for any replies in advance,
Cheers,
IMR and H 4895 are not the same, but, they do share ballistic properties. If you're using one and want to try the other, reduce the load by 5%, say, and work back up, same as you would when trying a new lot of any powder. You'll find max loads with one will be about the same as the other.
34 or 35 grains of either with 55 grain bullets shoots great in any 22-250 I've ever seen.

Now theoretically lot to lot can change on any powder, but I have not noticed this to be a fact. Apparantly some claim to have seen a change in lots to a degree of concern with certain powders.

The question is, is the IMR-4895 as "short grained" as the H4895?
Have you tried any of the surplus "Pulled-down 4895" and is it also short grained? I see some very reasonable prices on it at our Gun Shows.
Thanks.

Yep!! Shoots fine. Don't know short or long. Just know it is cheap. For Garand loading it works fine. Do work up your own loads. Do not just pick a "4895" load out of a book and go to it.
Hodgdon has used a number of suppliers over the years to manufacture powders to their specifications (or has adopted a manufacturer's powder as their own and then "spec-ed" it to match what was available). Anyway, the specs for H4895 have always matched the original military version, and therfore IMR 4895, very closely. I liked the Scottish H- version a bit better than IMR, but haven't used the current H- version which is probably Austrailian. At any rate, most any 4895 you come across will be within a percent or so of any other. So use the one which is most available/cheapest.
By the way, I've never found a powder I liked better in .22-250. 35.5 grains under a 55 grain bullet has been a good and reasonable load in my guns, but start lower to make sure about your gun.
Next C&E Gun Show in the Charlotte area is in early April, so hopefully I can get 8# of the Surplus "4895" then. I know one guy who sells 8# of WW-748 for $89 including the tax, so I guess I'll have a truck full of Powder.
Thanks again for the information.
