I took a quick trip to the range
As I wanted to do a 50 shot group test out of my Sig 229 with cast bullets out of a loaner mold
Not bad , about normal
So I will cast up a bunch to try
But not what I was wondering about
One of the older members was shooting a 6" S&W 686 357 Mag
His loads sounded like a normal 357 Mag factory load
On the plastic ammo box the label read Hornady 158 gr HP , 16.6 gr H110 , CCI SP and 1.58" OAL
Nothing out of the norm
But the bullets were sticking WAY out of the brass
Also he was using Winchester 38 Special brass
I have heard of doing this before , never tried it
We talked and he said the OAL is what affects the pressure
Not the length of the brass
So if I understood him
Crimping a bullet in a case at the proper OAL for a 357 mag will give him the same pressure
As if he used the longer 357 Mag case and the same 1.58" OAL
Is he right ?
Or what
