Preferred velocity range for 185 JHP long line loads?

Post by Taroman on 3/14/2018, 4:55 pm

First topic message reminder :

My club usually (always always) runs its pistol matches at 25 yards.
Now they're having an EIC-type match.
Reading that many prefer the Zero/Nosler 185s for long line, so I stocked up on them.
See many references here to powder charges here, but seldom related to velocity.
As we all know, a given load will produce different velocities in different guns.
Just chronographed my first test loads with 4.5 grains of Bullseye.
In my CZ97b, it gave me 747 FPS with a SD of 11.3.
Is this in the preferred range?
I am somewhat time and resource constrained as I have only a few hundred JHPs and it's an hour each way to the club for testing.
So, having a ballpark velocity may save a lot of wasted time and bullets.

thanks.

I do this.

To be completely honest, I often fully skip the second sentence.

I just crono'ed some Zero JHP's with 4.5gr Tight Group. My COL is 1.225. They averaged 744fps.

Let a Ransom Rest be your guide, no two barrels are the same. Doesn't matter how fast the bullet is going in this game, just the size of the group at 50 yards.
Try 5.0 WST, Winchester large pistol primer, 1.24 OAL.
