Yep me too. I've posted here before having seen a Smith M15 with 5 bullets stuck in the bore, military hard ball too; and suffered no discernible damage. No bulges, or rings in the bore whatsoever.Wondering how you could possibly have bulged the barrel with a round that didn't have enough pressure to get the bullet out of the barrel...
We surmised that the first round fired was a squib, and the rest stacked up behind it. Later that day, we fired it again, after gunsmith inspection and shot a sub 3" group at 25 yds with it. Rod
