there is a link to all of my data from last month. should get you started anyways. all shot out of a 5" briley custom gun with a briley barrel.

 

the n320 is at the bottom and i didnt test much since i found major pf very easily. the GAT bullets are powder coated and the bbi's are hitek

Did you ever get it figured out?

Yes, had to put on little more powder. 5.3gr, pf 950 to 960.

I picked up N320 recently because it was on sale at sportsmans for $28 per pound. Going to use hornady 180gr bullets with it 

[pjb45]

Bullet=Zero, 200 gr

Powder=320 4.4-4.6

OAL=1.175

Nowlin barrel is the tightest and requires less powder, followed by the Kart.  The Schumann (SV also) requires more powder.

 

I chrono all my rounds.  My CED was upgraded but still reads low.  Easy to make 168-173 PF in all barrels.

 

Changing bullets and OAL will change velocity!

I think you just made my life easier.  I'm in process of switching to Zero bullets and have been searching for data for their 200gr bullets.
