I'm about to cast some 287308 for my .280 rem. This bullet ive seen described as designed for the 280 rem. I cant find any load data for it specifically in 280 rem . (168g round nose gas check)
First round of casting im going to try clip on wheel weights, after they are gas checked and powdercoated ill weigh them. (ill size to .285 as well) Assuming they are in the neighborhood of 165 im planning on giving them 37ish grains of win 748 for a targeted 1900-ish fps
Id like to talk about any 7mm cast sucess ???
Anyone with interest in trying a few of these boolits im happy to share or swap a few.
Thanks !!!
Ben
