Need help with 40S&W Lead Bullet reloading
I need some help. I just started reloading and purchased some lead bullets in 40 S&W 180gr. TCFP that are .402 diameter from a auction on reloaderauction.com. I reloaded about 25 rounds with Hodgdon HP38 at 4 and 4.2 grains. My concerns are that there is a noticable bulge in the casing with the bullet seated. The company I bought the lead bullets from said they were pre-sized. Is this bulge common with a lead bullet, or do I need to resize them down to .401 or .400? Also, there is very little load data that I can find and do you think my load will be to hot or too little?
