i would go for 300 , if its H&H, Win mag, o Wby doesn `t matter there fine, however i like the bullets a little bit over the 300s so i would also add, 358 norma magnum, and to next spring .323 PH , but the 338 and the 340 is super,but the best choice would be the 375 . Either H&H or WBY. but a 7mm is alright, like the rem mag or the wby. ill have to stop there .
