Not all bulged cases are the same. Here are some bulged cases shot in looser chambers. Most of these will fully resize in regular sizing dies.
They can be resized flat like this (If they don't fully resize on first attempt, I rotate the case 90 degrees and resize a second time. If they won't drop in tight Lone Wolf chambers freely after being resized twice, they get recycled). BTW, I used regular Lee carbide sizing die. If your cases are bulging and you are not comfortable about reloading bulged cases, reduce your charge, change powder or use an aftermarket barrel that has tighter chamber that won't bulge the case. All of my spent cases from Lone Wolf barrels show no bulge.
