Powders for 9my 147gr coated

[muncie21]

If you like N320, try Prima V.  Shoots clean, load is similar to N320 and about half the price.  What's not to like...

I have been loading with w231 and will be chronographing next week hopefully. polycoated 124gr SWC , 1.050 oal, 3.4 gr W231. also loaded polycoated 147gr FP, 1.130 oal,  3.2gr W231.

hoping to see which groups better and meets minor PF for USPSA/Steel.

 

Both are loaded on mixed headstamp Blazer and Winchester brass

CCI small pistol Primers

hornady Die set(seperate expander die, Decap/resize, Seat/Crimp combo)

 

Soon as i get speeds ill let you know

I loaded up some test ammo using Campro 147 gn RNFP bullets, 3.2gn VV N320.  COL 1.091.  PF 124  Pretty much makes my Shadow 2 feel and sound like a .22.  Cases literally “tumble” out of the ejector, yet not one single stove pipe or jam and respectable groupings.  I loaded 600 rounds for practice and will up the powder to 3.3gn for comp to make Minor PF.  At 3.5gn I was at 139 PF and wanted to bring it down a tad from there.  I definitely prefer the N320 over the N340.  Next up is the elusive N330.  My COL is 1.091 as per bullet manufacturers recommendations, my Shadow 2 can take 1.177 according to the dummy fitting I did this morning, is there a significant difference between a longer and a shorter COL?  I’m thinking longer must be faster and therefore more accurate?

Longer = lower pressure = slower. Generally speaking the faster you push a bullet (within reason) the more accurate it will be. Depending on the powder you'll see a velocity difference of approximately 20-60 fps when changing the OAL.

 

P.S. Your OAL of 1.177 cannot be correct, I'd recheck that measurement.

 

P.P.S Here's an example of how the OAL might affect velocity.

Thank you for that explanation, I appreciate that!  You’re absolutely right that it wouldn’t take 1.177, it’ll chamber, but it failed the spin test.  I dropped it down to 1.10.  Reloading is turning out to be a lot more like cooking than I thought it would be and.here I am, right back in the kitchen.
