Roscoe Regulator Posted October 4, 2018 Share Posted October 4, 2018 I use 357 brass in my Lightning rifle. I use a trim length of 1.275, 3.2 gr Trailboss, and limit velocity with a 158 gr TCBB by Penn. COL is 1.577. Link to comment Share on other sites More sharing options...
Lead Friend, SASS #53635 Posted October 5, 2018 Share Posted October 5, 2018 I’ll play. I use 3.2 of Red Dot under a 125gr Hi-Tek coated TCFP with an OAL of about 1.58 for my Marlin and a Miroku 73. They eat ‘em up. Never trimmed a case in my life. Link to comment Share on other sites More sharing options...
