Thanks for the answers.
I was wondering if it was a variance in published vs actual BC ratings that caused the change in effective range values.
Agreed, the manufacturing industry changes too quickly to constantly publish new handbooks. "Insert cards" would be easier and less expensive for everybody. However, I was thinking more of a bolt action/single shot specific volume since volume 1 and 2 focus almost exclusively on the AR15.
Currently I'm using a 16" Howa at a location to hunt up to 275-300 yards, but am scouting a couple of new locations for next year. The last bear was 265 yards and it was a complete pass through. So your most recent numbers at least appear to be reflective of field experience. The new locations are up to 400 yards and I was thinking of using a 20" Howa for them. I use your data heavily along with my range finder when considering a new location and weapon choice. 300 yards with a 16" barrel looks to be well within effective range at 300 yards, but 400 yards with a 20" barrel may be pushing it. It could be time to "step it up" to a 308 or 6.5 CM.
Thanks again for all of your work and, more importantly, sharing the results with us.
