I remember doing the daily jack-rabbit walk with either a .22LR, a .222 Rem, or a .243 Win. The latter two were all handloads. Later, after I plugged the barrel with a squib load, that .243 Win. became a .257 Roberts. I technically plugged the barrel, but in fairness I took it to a guy who knew how to get the bullet out. That resulted in the bullet being peened into the barrel necessitating a barrel change. My dad wasn't mad. He was glad I didn't kill myself by firing another round in the rifle. AND most importantly, he had an excuse to put a .257 barrel on that rifle.
