Hi guys. I'm looking at .40 again. Also peeping at 10mm and .45. I reload mostly and I know there's a big difference in availability. Availability locally and price. Help me settle on one. I shoot high volume but thoroughly enjoy load development and accuracy. I tried an older gentleman's m&p full size .45 last weekend and it was dead on at 25 and grouped very well with box ammo. I love the .40 though. Its cheap to load and conventional now. What to get????
