Has anyone tries the campro plated bullets in full power 357 loads? Their sight says that it's ok but looking for advice before I load some of the 125gr in front of 19gr of w296
I've done it with H110 powder, when trying to figure a load for my Henry Big Boy Steel in .357mag (that's a 20" barrel). The results were... disappointing, to say the least.
Brass is Winchester fired once, Primer is CCI 550, Powder is
19.0gr of Hodgdon H110, bullet is
Campro 125gr FCP-TC, COAL is 1.590". 10 rounds from a bench rest at 100m:
I also tried with 20.0gr of powder, I was still getting >10MOA in spread, so the remaining bullets are left on the shelf unused.
Brass is Winchester fired once, Primer is CCI 550, Powder is
15.0gr of Hodgdon H110, bullet is
Campro 158gr FCP-TC, COAL is 1.590". 10 rounds from a bench rest at 100m:
I tried those bullets with different charges on another day, and there seemed to be a possible accuracy node for me around 16.2gr, down to about 3-4MOA for those 158gr bullets. Unfortunately I noticed I had a wobbly scope on that day so the results got discarded and I still have to re-do those tests.
For comparison:
Brass is Winchester fired once, Primer is CCI 550, Powder is
21.0gr of Hodgdon H110, bullet is
Hornady 125gr XTP, COAL is 1.590". 10 rounds from a bench rest at 100m:

15.0gr of Hodgdon H110, bullet is
Hornady 158gr XTP, COAL is 1.590". 10 rounds from a bench rest at 100m:
I've come to the conclusion that my carbine just doesn't like the 125gr weight bullets very much. I have a heap of free Hornady 110gr XTP I got from their "get reloaded" promotion, finding if they shoot straight will be one of the jobs for this spring.
