Reloading N320 for 45ACP wadcutter loads

I'm currently using 185g Zero LSWC bullets in front of 4.2 Bullseye.  They have been reliable loads for indoor and outdoor.

Does anyone have any recommended load data for the same bullet in front of Vihtavouri N310 or N320?  I have powder in both and am considering using them given the general unavailability of Bullseye.

Thanks,

Steve

I had some success with 4.5gn , I like VV310 and WST better for SWC. Very Very Temperature sensitive, if you are loading w231, pretty much the same charges -0.1 , maybe a little higher pressure than w231.

Try 3.8, 4.0, or 4.2 gr. N310.  One of those should group well.  N310 is much cleaner than BE.  In general, use 10% less of N310 than you would BE to get the same velocity.

You'll probably find that 320 will give you inconsistent recoil shot-to-shot at our reduced target velocities.  I definitely prefer 310 over all other powders.

Thanks, gentlemen, for the data....just what I was seeking.  The good news is I erred in thinking I had N320!
