I'm fairly new to reloading (about 500 rounds so far) and I'm trying to figure out why Meister Bullets hard cast .40 cal 155 gr. work pretty well at 1000 FPS and spray all over the place at 1200 FPS. Is this normal with lead? I'm shooting these through a Glock 35 using a Storm Lake barrel. With a 5.3" barrel and a 155 gr. bullet, 1200 FPS can be achieved with standard cartridge pressures, so I'm wondering why accuracy is so bad. Is the friction melting the outer edges of the bullets as they leave the barrel or is the pressure behind them so high that the relatively soft lead gets deformed to the point that the bullets can't fly straight? I'm confused, thanks for your help.
