So my wife wanted to try her hand at trap. She's is petite and recoil sensitive, so I scored an autoloader for her. She loves the gun and actually broke about 8 birds her first time out (no doubt a result of amazing coaching). The gun I found was VERY lightly used....cannot tell it from new. I scored some one ounce loads for her and they would not cycle thru the gun. I tried my factory 1-1/8 1145 loads, and those cycled just fine. Is there a spring or something I can change out to allow her to use 1 oz loads, or should I have her stick with 1-1/8? Thanks!
