Re: 375 H&H for long range
Won't affect velocity, will stabilize the bullet. If you increase velocity you can get away with a lighter twits, ie a 378 Weatherby in 1-11 will stabilize the 350SMK. You are stuck with a 375 H&H velocity wise. Hence the need for a tighter twist such as 1-10. You may try the 300 grn Accubond. I have had great results with that bullet to 800 in H&H. Look at the charts and determine. Sometimes BC is not everything.
