[QUOTE="Bret GRAVELINE Graveline, post: 2118689, member: 108926"] Trying to establish the OAL from blue prints works if the lands and grooves are to exact diameters, years ago black star barrels were popular, they tapered the lands at the breech were all over the place, the OAL could vary as much as thirty thousands from barrels that were ordered and received at the same time, I found a difference of 3/16 when chambering a black star and a pacnor at the same time with the same teamed, you can have the mag box lengthened by a good smith, I converted a good number of rugers to true magnum length, 416 rem ultra mags 338 Lapua, having the mag box lengthened is likely to result in a longer turn around time which is always a down side [/QUOTE]
