Re: Hornady 180gr interbond and varget load data?
Just started working up a load for my Rem 700 Sendero in 300WM using the 180gr Interbond and some IMR4831. Got nice results using the OCW method.
Barrel is factory 26" with a 1/10 twist. Was able to keep them mag length but still seated .010 from lands.
Far be it for me to say but maybe 400 is a little too far off for a ladder test using this bullet out of 308 to not have other factors mess your resutls up. But I may end up corrected here before I know it.
