I recently tried 8208 my 204 for the first time and do not plan on shooting anything else. I'm getting 1/4 moa with 27.7 grains over a 31 grain hammer hunter at 4080 fps. this combination has yet to have a group exceeding 1/2 moa.
Exactly that load here as well in bog standard Tikka T3. It is made here as ADI BM 8208. We generally refer to it as Benchmark 8208. Often rebranded for sale in the US. I highly recommend this powder for this combination and for 32 grain pills as well.8208 is the only thing I've used in 204 for a long time. I run 27.3 with 39 Sierra and 40 Bergers at 3800-3900 depending on the barrel. I run 28-28.5 with 35 Bergers at 3950ish. Start around 28 and work up with 32's. Haven't seen a 204 shoot bad with 8208 yet
