All Model 1187 target barrels are stamped "FOR USE WITH TARGET LOADS ONLY". Target barrels are not pressure compensated. The gas orifice holes are over sized to allow the action to cycle with light loads. Firing heavier field loads will result in excessive wear on internal components. If you need to order a replacement barrel that will handle heavier loads, you can contact your local dealer, visit our online store at www.shopremingtoncountry.com, or call our parts department at 1-800-243-9700 M-F 9am-5pm EST.
