1st post and a new build
#9
Welcome aboard. We (many forum members) spent some time on a lot of the details of selecting a barrel length for hunting, taking into consideration whether the hunter is stalking, stand-hunting, or both, and what region they live in. Also covered are projectile selection for animal types and sizes.

We compiled this data into the 2nd Volume of the Reloading Handbooks.

There's a graph on page 13 with barrel lengths ranging from 10.5" to 24". There seems to be a sweet spot for effective hunting reach with the 16-20" pipes, all of which give you a point blank range of 250yds. This graph was made with the 123gr SST as the baseline, sea level, 59 * F.

10.5" expands out to ~260yds, 225yd point blank
14.5" expands out to between 350-400yds PBR 240yds
[COLOR="blue"]16" expands out to between 400-420yds PBR 250yds
18" expands out to between 410-440yds PBR 250yds
20" expands out to between 450-490yds PBR 250yds[/COLOR]
24" expands out to 500-520yds PBR 260yds
