Eddy, funny Rich at Sierra told me yesterday he is running a 6x47 and 22x47, latter 80/3600 and 1" on a good day at 600 yds, 2" any day, NOT bad. 3200/107 in the 6. No info given on Bbl length. For me I want no more than 24 on a hunting rifle for how I hunt so speeds may drop a little.



22 cal 40 grainers at 4300 are pretty cool too. There is a pretty large velocity drop stepping up to the 90s in 22 cal, but not so much stepping up to the 115s in 6mm. His experiance with the 22x47 and 6mmx 47 are very similar to my own. My hunting is always geared to long range so the longer barrels do not scare me any.
