Please explain what JSP bullets are and what is their intended use.
Thanks
Thanks
I think increased muzzle velocity could give the nod to the JSP, especially in larger game.
Yes, that's correct. I meant that by driving the JSP bullet to an increased velocity (over the JHP) it would perform better by penetrating deeper while still expanding. The JHP opens too quickly when driven at increasingly higher velocities. I was referring to "controlled expansion" of the JSP over the JHP.What increased velocity? A 158gr bullet is a 158gr bullet.
Here's a good example of the difference between JSP and JHP in Hornady's XTP bullet line for .357 caliber.
I've shot quite a few deer with Hornday XTP bullets in 357mag. The difference in performance between the XTP JSP and the XTP JHP is quite a bit at the same velocity.
The difference in performance between the XTP JSP and the XTP JHP is quite a bit at the same velocity. The JHP expands rapidly and the JSP penetrates deeper with a bit less expansion. .
That's my experience as well. That Flat Point XTP acts like a soft point on deer (deeper penetration at carbine speeds).Hornady does not offer a 158gr JSP in their XTP line in .357 caliber. They do offer a a 158gr XTP-FP, which still is a HP, but designed for higher velocities and deeper penetration than their standard XTP-HP. It differs from a true JSP because it has no exposed lead. It is my preferred bullet for hunting deer with my .357 carbine.
