[QUOTE="yobuck, post: 515139, member: 12443"] ive used a 30x378 weatherby on a custom action for about 25 years. there were very few powder choices at that time. the most popular was h570 which is a ww2 surplus powder. h870 also worked well as does wc872. the most popular bullet has been the 200 gr smk. with my 36" barrel it will produce about 3500 fps with 113 gr. h570. 118 gr. h870 will do likewise as will wc872. im of the opinion 869 is similar to h 870. there is no doubt the energy of the heavier bullets is superior to the 200gr. but for flatness out to about 1500yds its no contest. the 200 is better than the 220 and the 240. at least thats been my findings. from a 100 yd zero i need about 38 min. @ 1500. the accuracy factor could be better however and ive not tested them enough to determine that. back then the 30x378 was the ultimate long range cartridge. it no longer holds that distinction. the 300 ultramag is almost as good and the big 338s are superior. is there anything you dont have joel? do me a favor and go shake bruce. tell him some old guy would like his gun before he croaks.
