Over on Accuratereloading.com some guy says he ruined his Krieghoff barrels by using foam filler plugs....has anyone heard of such a thing? Doesn't foam "burn away before it even reaches the bullet? I shoot reduced loads all the time so I can have all the fun without the bruises and get similar accuracy to Hot Loads up to 80 yds. I think it was "pilot" error. Wrights book says there can be problems but doesn't says you'll blow your barrels apart...
