Thread: 18 inch 308 powder

Greetings Niceandfar,
Agree with the bulk of the above BM8208, AR2206H and AR2208 will all do the job as long as you can fit enough AR2208 in the case.
Regarding AR2206 and AR2206H. AR2206 appeared about 1980 as an improved version of the earlier AR2201. AR2206 was the first of the commercial powders offered by Mulwex, now ADI, and was the first of the temperature stable powders called extreme powders by Hodgdon. ADI started making powders for Hodgdon in the early 1990's and AR2206 was slowed a bit to match H4895 and given the H suffix. AR2206 appears to have been discontinued some time after 2000. Similarly AR2213 was slowed to become H4831SC for Hodgdon in the mid 1990's and replaced AR2213 as AR2213SC in the Australian market about 2000. ADI also makes the old chunky H4831 only for Hodgdon but not for sale under the ADI brand.
Hope this is clear Grandpamac.
