.280 AI

[Drjones65]

Dumb question but one I can never geta a straight answer on...H4831 vs. H4831SC.
I load the H4831SC in my 300 WM with 180 GR HH bullets. It shoots amazing!
I'd like to develop some loads for both my 280 AI and my 28 Nosler but data usually only list the H4831.
People reference H4831. Several references in this thread.
I know the SC stands for short cut and I also know that the two powders are not interchangeable.
How much difference is there and can one develop loads around the H4831SC when only H4831 is listed?
I like 168 GR Berger bullets and if I could figure out he Hammer bullets I would use them too.
I have 8 lb jugs of the H4831SC and I'd like to use it.
I shoot Cooper of Montana rifles.

"Hodgdon's position has consistently been that H4831SC is the ballistic equivalent of H4831.
The SC version is simply manufactured with shorter kernels. Their published data is intended to apply to both powders."

I like H4831 I think I shoots a little better than sc because of a better case fill if you can get enough in case and I never had that problem. JMO

I'm curious, ( Dr Jones ) if I read your post right, why do you think would H4831 & H4831SC are not be interchangeable?

 

[johnmyers]

Case fill is different it would be small but still different

A few of my final loads in 24" proof
* 140 Abs Hammer / H4350 = 3330fps
* 168VLDH / RL23 = 2960fps
* 180VLDH / RL23 = 2930fps

Previously used H4831sc with 168s and works well but give up some velocity. Have several 160 AccuBonds but have never spent time working up a load.

I agree. But I use "SC" over standard H4831 only because I am shooting a compressed load.
Otherwise, I probably would not care

Need to reread the Hodgdon reloading manual. There no difference, just one flows better. I would think the Short Cut would be more accurate in scaling the powder out. That powder is very temp stable too. H4350 is very stable and a little quicker burning too.

Just put on my new barrel on my Rem 700 last week.
Need to order my At-One stock for it next week.
Have a big Vortex to sit on top of it.
Have everything to reload for it.
Can't wait!!!
