Ar2213 got changed to ar2213sc the sc is shorter cut...they made the length of granual logs shorter...that's it.no other change. Weird that you suggest it got slower burning as normally making something smaller means it burns faster.its great powder

These were both slower than AR2213, based on the ADI November 2000 Guide, to match the older H4831. I suspect that ADI stopped making AR2213 at the same time but it took a few years to run down their stocks prior to releasing AR2213SC on their local market. AR2213 was already a SC powder same as all the other ADI powders but ADI used the SC to indicate a lower speed same as AR 2206H being slower than AR2206. AR2206 was closer to early IMR8208XBR in speed from my chronographing although this may have changed. I really should test that.

Loaded up 25gr with the 65gr after an anonymous member said it was too slow. Harvey has maxi at 26.5gr.Quote:

Shortening the grains allows more surface area for the retardant that’s applied to the outside of the grainsQuote:

Technically any configuration change of a powder may alter burn rates but in practical application may not ( always ) be apparent. I use AR2213 ( agree with MD, it is a fantastic powder ) and did a bit of a test of batches with 243W handloads a few years ago. Had some old, old stuff in tin cans ( Mulwex label ), some early 2213sc and some very recent 2213sc. Just compared one adopted load using exaclty the same charge of each powder shot through a chronograph. At 100 yds all MVs and POIs were the same. There may be others but it's the only powder I use giving such consistency from batch to batch. I don't bother comparing loads when opening new bottles / batches of AR2213sc.Quote:
