Was looking at some 357 Mag. JHP +P. What does the +P stand for?

They are high pressure loads. Check with the ammo manufacturer since sometimes these loads are only recommended for use in certain models of guns.

I have been shooting them out of the Trooper. They seemed to be fine with a little punch. Just was trying to find out some load info on them. I got these for free. Came from a Gunshow and "Deer Stopper" is on there package. I see they are a Gold Dot bullet. I think I am just going to stick with the XTP. I am not trying to hot load anything!!

The trooper is probably rated for the +P but you may want to find out for sure before you shoot any more of them so you don't damage your gun

Thanks Rod! The Colt has a pretty stout frame and barrel, but I am checking to be sure. Going to start from scratch until I find out some more. Got some new brass on the way with some 158gr. XTP. Thinking about 15. of H110. Any thoughts?

Just got an email back from Geogia Arms and they said the DeerStopper Round was below and of course, I could buy some more!

+p = pressures above standard accepted



you don't just arbitrarily select a load to go with, especially if it is a max listing. you work up in increments and see which powder/bullet/charge is the most accurate in your gun.

This is not Max.

you made me go look

....and you are correct.

15.0gr is a starting charge and max is listed at 16.7 with the 158. so....load at 15.0, 15.5, 16.0....n maybe 16.5....n see what load is the most accurate, or if there is a preference.

Thanks for your concern Kyode. I am very cautious about loading the bullets. I guess I should have just started this post out asking what people thought of the H110 with 158 XTP for 357 Mag. I was trying to compare it to what I had already shot. On the "Deer Stopper" package it was saying Velocity of 1475, H110 was starting out 1418. I haven't used H110 much except in the my 629. And I like it!!

Kyode is first rate… he also knows a thing or two about reloading. But the truth be told the reason he said something is because he truly cares. A lot of times we are overly cautious on the forum just because we don’t want to be misunderstood. Lets face it, I just mentioned that I was shooting hot loads (what I would consider max loads) and someone (in good form) was cautioning about not pushing a cartridge beyond its limits. What a great group of people as far as I am concerned!

TC, you are right on there! This site is loaded with a great bunch. Including Kyode!! It is good to have people to go the extra and make sure nobody is munking up their guns or fingers. I appreciate his comment and outlook on the situation. I am still a newbie at the reloading so I may catch myself with uncertainty driven by curiousity. Hell, until I got on Handgun Hunter, I had never even considered reloading. And now, well, I am a junky for it! Thanks guys!

I like to reload almost as much as shooting and hunting. And all the neat gadgets that you don't really need, and the different bullets, and powder and.......... sure is a great way to have fun.
