A alloy can with out steel blast baffles will wear out even quicker .
BT in europe use steel and SS in their 338LM cans , Canadians use a large TI welded can , anything less will not last very long , I have a ATEC strippable can , its 1st 2 baffles are SS and then aluminium , and even at the 3rd baffle spacing on a 308win cal rifle , its getting gas cut in less than 300rds .
All will wear , BUT some materails much quicker than others , ME I like my stuff to last more than a couple hundred rds , I like thousands of rds before replacement .
