I shoot Cowboy Rifle Silhouette using a Rossi 92 in 357 mag with a RCBS 180gr sil cast bullet. My load is 10 gr of AA9 with a CCI Small Pistol Primer and the RCBS sail bullet which weighes 190 gar from my mold. I use a 38sap case for this load because OAL is to long using a 357 mag case when the crimp is in the cannelure. I get right at 1300fps with this load with no signs of pressure. According to my calculations, I get a .83 foot pounds per second at the 200 meter ram, which seems to be enough because it knocks them down every time I can hit them.
My buddy wants to try my load in his Marlin Cowboy in 38 Special, for the same purpose. I figure that his action is probably just as strong as the action on a regular 1894 Marlin and it should handle the load fine.
Any opinions on this? Let me know what you think!
