If you meant to quote me i was saying the xbr8208 was touted by hodgdon to be a game changer in the benchrest game but i was saying its been out for 11years and hasnt yet. Before this shortage it was readily available at every store
I misread your post there. As far as I can see, the pre-production lots of 8208 XBR behaved rather differently (better) and the powder never fulfilled its promise after general release. If I have my facts right, this is Hodgdon / ADI's second unsuccessful attempt to knock Viht N133 off its BR perch as H. Benchmark was likewise promised to do this a few years earlier prior to its general release.
I used quite a bit of 8208 when we could get it in 308 for F/TR. I found it an excellent powder for 155s and it was my go-to for the 155.5gn Berger. Others here also tried it in 308 and rejected it as not giving high enough MVs in this application (as did US F/TR team members in the run-up to the 2013 F-Class World Championship fixture). It is certainly a bit over 'quick' for 185s and heavier bullets in the cartridge.
