I recently purchased a Japanese made A5 Browning light twenty fitted with the Invector choke, not the Invector Plus, system. I have a Browning full choke tube that is stainless steel and is labeled for lead. Then I have an improved-cylinder choke tube, not stainless, labeled Browning, but without mention of lead.
So, are all Browning stainless Invector tubes for lead only? Are those not stainless compatible with "steel" shot or for steel shot, must one have a barrel with Invector Plus tubes?
Please help me understand this. Thanks.
