[QUOTE="Sheldon Root, post: 2572199, member: 112458"] FWIW. I had a Wby 30.06 action so had a custom barrel made for it. 24" 1:7.5 gain twist. Chamber was machined to have .045 th. from the ogive of a 115 Barnes TSX FB to rifling. 70gr. H1000, 215 Federal primers. Set the scope with bore sighting done at 30yds. 2 shots to get to 0 at 100 yds. First set of 5 shot group came in at 3/8" at 100yds. Velocity over chrony avg. of 3296 fps. Settled for that load so not hard on barrel and cartridges are factory length. I am happy with that. [/QUOTE]
