In all seriousness, a boattail and a nylon tip could combine to add 100 yards of effective range to a 375 H&H - using Barnes bullets recommendations for suggested impact velocities. Barnes recommends over 1900 fps.
By comparison, the 260 grain Nosler Accubond - maintains that velocity for more than an extra 100 yards.
I just wish Barnes would add a boattail option and a tip to their 375 offerings.
