I have a 358 JDJ and love it! So far it is as accurate as I ever could have imagined and with the muzzle break on it the recoil is not bad at all. One thing I do not know is its trajectory. I have it sighted in at 100 yards(1" high) but I do not know where it will hit at 150, 200, 250 or 300 yards? I do not have a range or anywhere where I can try it out at these ranges so if anyone knows or has a computer program they could put my data into I would appreciate it. Here is my info:

225 grain Nosler Partition bullet
51.5 grains of Accurate Arms 2520 Powder--Thanks for the load Graybeard! Last shot-3 shots .65" group @ 100 yards!!
OAL= 3.237"
Avg. Velocity: 2282 fps.
Primers: Winchester Standard Rifle Primers

I would like to see just basically where the bullets would go at those different ranges. I will not hold anyone to what they say because in the end I need to try to find a place to try them out at those ranges but I still want to know what you have to say about it.

Thanks,

Bob

You might want to consider sighting it about 3" high at 100yds. That will have you dead on at 200yds, and about 13" low at 300yds.
With a scope the trajectory is as follows;
Muzzle: -1.5"
50 Yards: +1.8"
100 Yards: +3.3"
200 Yards: 0 {dead on}
300 Yards -13.2"
This was for the 2300fps muzzle velocity you stated. Unless you plan on shooting small vermin at great distances with that set up, the +3" high at 100yds setting will put you just about dead on at 200yds. Bear in mind there may be slight differences in "ACTUAL" trajectory but it should not be more than .5" at.
This will basically let you point and shoot deer sized and larger game out to 225-250 yards with out any "hold over" and still be in the vitals.

Doesn't really matter,
All that is really necessary is the muzzle velocity, and the bullet weight/caliber, & it's ballistic coefficient.
These parameters will get you within a inch or less.
My biggest concern will be the velocity threshold for bullet expansion. Most spire-point rifle bullets need about 1800-2000fps minimum for reliable expansion. With your current load that bullet won't slow down to 1800fps until it reaches approximately 250yds.
Quite the reach for a handgun that is capable of downing a moose.
