Ruger PCC load development

Recommended Posts

I am working on loading different weight bullets to see what my Pcc will like. I have several reloading Manuals but my Speer Manual has a note under the 147 gr. Bullet that the 147 grain is not recommend for barrels 10 in or longer, is this due to pressure or maybe velocity?

thanks in advance

I shot thousands of 147gr bullets through my 16" barrel without any problems.  The velocity will be higher on a 16" barrel.  

Here's one of my favorite loads for comparison.

Bullet Brand Everglades
Bullet Type Round Nose
Bullet Weight 147gr
Powder Name Titegroup
Powder Weight 3.0gr
Primer Federal
COL 1.130-1.135
Average Chronograph Speed 973.9
Standard Deviation 52.48
Chronograph Speed Low/High 890 1033
Power Factor 143

Is it for a particular powder or just a general note?

Just curious, if you only need 125Pf  maybe 130 PF to be safe, why do you run all the way up to 143?

The gun cycles better and the recoil is a push and not a flip.
