JSP versus JHP

[55larry]

Can someone explain the usage difference between JSP and JHP ammo?

In other words, I understand the physical difference in the actual round, but what I am asking is why you would choose one over the other. Under what situations or scenarios might you pick each one?

A lot depends on the caliber you are asking about.

In general, HP ammo is loaded more for varmint type use in the small fast calibers. SP opens a little slower and might offer deeper penetration on larger game.

HP is also often used for Match bullets, because the bullets can be made more precisely then SP, and also offer better sectional density.

In larger caliber hunting bullets, SP has long been the standard due to it's excellent performance on big game. HP's might open too fast and not penetrate as deeply, or even enough.

But today, the difference is blurred by modern bullet technology like the Barnes X-bullet HP and others. So now, there is no dividing line in performance or use based solely on whether it is a HP or SP.
It now depends much more on the bullet technology & construction then type.

Thanks for the info. I was interested in the difference for small caliber, specifically 223.

Would you use JSP for large varmints like coyotes, and JHP for home defense?

In .223, I use Hornady V-Max / Nosler Ballistic-Tip for everything.

The plastic tip bullets have all the explosive performance of a HP, with exceptional accuracy and down-range performance.

Are the remanufactured ones reliable? For example, cabelas has these 50gr Hornady V-Max bullets for $140/250.

Midway seems to be out of stock on a lot of stuff right now.

AFAIK the Army uses "remanufactured" match ammo. There's nothing wrong with it.

I haven't used HSM, but I think it's good. Black Hills is known to be good, and Cabela's has that, too.

The Black Hills with 50 grain V-Max works out to $180/250.

That said, unless you're going varmint hunting, I'm not sure why you'd want to pay extra for those V-Max bullets.

 

[55larry]

The benefit of the V-max over a normal hollow point is simply better long range accuracy, right?

 

[rcmodel]

Right.

They have a higher BC, which translates to a flatter trajectory at long range.

They are also among the most accurate bullets made, until you get into the very expensive Berger match bullets and such.

HSM is good stuff. I have a bunch in .223 and 10mm as well.
