You should find out what your choke constriction is before shooting steel. Although the Remington barrel is probably sturdy enough to stand up to steel shot without "ring buldging" (and I said "probably"), there is little need for a full choke constriction (calibrated for lead) when shooting steel. As a general rule, steel will pattern full with a modified (calibrated for lead) choke constriction, and over constricting will damage the pattern and possibly the barrel....measure your bore, measure your choke, and determine the difference in those diameters; this will give you your choke constriction.
