I agree 100% with BKS1.
Hornady’s .30 caliber 150 grain round nose is probably a very good bullet in the .30-30 for average N. American deer, pronghorn, coyotes, etc., and fun for target practice.
Hornady bullets in all calibers I have tried are usually very accurate.
Admittedly, I have not shot any animal larger than a jack rabbit (very similar to the African hare) with the .30 caliber, 150 gr. Hornady RNSP.
However, I have examined a coyote (“North American Jackal”), taken while quartering toward the shooter, with this bullet, fired from a .30-30 at approximately 150 paces.
Judging by the fist size exit hole, I am convinced that the bullet deformed (“mushroomed”) properly.
Anyway, my opinion is based primarily on the following:
I have been reading as much as possible about bullets and I’ve been hand loading various caliber Hornady plus other brands of bullets into various cartridges since approximately 1967.
Several of my friends and myself have shot various calibers, weights and brands of bullets into various material, including live animals during hunting seasons.
Personally, I have shot approximately 200 hoofed animals, with various calibers,
from various brands of bullets in various weights.
I conclude that all bullets, made by all bullet companies, including Hornady, are not suitable for all tasks.
A hunter should match the caliber, velocity, bullet construction to the size of animals hunted and also consider the conditions of the chosen hunting area.
Again, the bullet in question is a very good one at relatively tame velocities and definitely not for larger animals, IMO.
