All the talk about Lil Gun got me thinking about H-4227 in the 480.
I have NOT seen any signs of erosion in my 480 with the Lil Gun. H-110 was giving me erratic velocities in cool temps no matter what primers I tried.
I didn't have H-4227 on the shelf so I never tried it. Used to use it in other handguns with good results. Anyone using it with 400ish hardcast? How is velocity & consistency?
