You can join Target Sport USA for $100 a year to get free shipping and 8% off their price to the general public. I've been buying 9mm New Republic, or Blazer Brass 115 and 124 gr for .21 cents per rd with no shipping cost and fast delivery. The cheapest .380 I've found is the TSUSA New Republic for .26 cents per rd. You can buy the New Republic 9mm for 6 cents a round more than the cost of reloading the .380. Additionally you can get lots of basically free training with the cost of the MantisX training system. The new Mantis Titian laser pistol is only $200 with their Mantis device built into the pistol.
Many highly required profession trainers will recommend dryfiring practice-lots of practice, but it has to be practiced correctly and a method for getting feed back-Mantis helps a lot. Additionally don't discount live fire practice with the .22lr. Stance, sight pic, trigger control, grip control etc. are the same as with center fire except for recoil control for fast, accurate follow-up shots. I've taken a number of classes from Karl Rehm-KRtraining Systems. He recommends 10 dry fire snaps for every live round shot. But each trigger pull has to be thoughtful, intentional with focused attention to what is happening and feed back as to the results. Thousands of rounds of just punching holes in paper or ringing a plate without intentional thoughtful practices, IMO, skill level will plateau soon without thoughtful training. You can also learn a lot from some of the better Youtube channels. I especially like Tactical Hyve channel.
