Hello all, first post here, this forum seems like the best place on the 'net to barrage with stupid questions, so here goes:
I have been reloading for a year now but am still a newb. For my last batch of .380 (fed to a S&W ppk/s) I opted to reduce the charge, from 4.0 gr Unique to 3.8. I had no problems with 4.0 other than that the recoil seemed excessive compared to factory ammo (rws, wwb, and various SD rounds). Here is the recipe:
3.8 gr Unique
Rainier 100gr plated RN
Mixed brass, mostly winchester
Federal primers
OALs between .960 and .985 (I tested in .005 increments)
When I fired these rounds I had terrible accuracy and noticed some unignited powder. On the occasions that I could see the bullets progress (very bright sun that day) I could definitely tell it was not heading towards the point of aim. My first thought was that 3.8 is too low, although I have seen loads online go as low as 3.2gr of Unique for the same bullet. Is this indeed the most likely cause, or could I have screwed something else up? Too much/little crimp? Bad primers? Light primer strikes? It's driving me nuts!
