I told my nephew I would load for his .32 Winchester Special because he can't find any factory ammo. He gave me two types of brass. The brass from recently purchased Hornady FTX ammo measures just under 2.040 (which is the spec max length). Brass that had been loaded with flat point bullets measure just under 2.000". I believe these were handloads prepared by my FIL's brother. The sources I can find state trim length is 2.030". He has much more of the short brass than the newer hornady brass.
What problems might I have using the shorter brass?
