Have any of you guys tried the new IMR-7828 sc powder. From what I've read it looks like it might help get a little more velocity than with the regular 7828.

I've loved it in my weatherbies. Very consistant. Now I'm wondering with the new short kernals how much of this we can cram in to the 30-06 based cartridges!!!!!

Will probably work real well!

270bdl, IMR7828sc should certainly be a worthwhile improvement and addition, as the improved loading density will certainly enable you to get more velocity in situations where the regular 7828 achieves 100% loading density at less than maximum pressure.

I have tried the regular IMR 7828 in a variety of cases and with the heavier bullets it usually gives the highest velocity. However, on the down side, I have found that it is temperature sensitive and very spikey around maximum pressure, and for this reason I don't use it in my field loads.

To complete their line of powders I would like to see them give IMR 4831 the sc treatment, and also add another short cut extruded powder which is slower than IMR 7828, and a little slower than Re 25, H1000, and Viht N170. Regards, Brian.
