357 SWC at rifle velocity?

Post by Oldbrass » Sun Oct 11, 2020 12:36 pm

I've got quite a few (Lazercast) 158 hardcast SWC/hot dose of W296 loaded for a a ruger GP100. These are not gas checked and am concerned about bore leading. Anybody try these in a lever gun?

Lazer cast bullets are quite hard like 21+ Bhn and you should be good to 1500 FPS.

Shoot some and see. Take some jacketed with you to shoot after you have shot a bunch if you see any leading in the barrel after shooting them.
Don't let the old man in

Shall do just that big al, I've also got piles of 158 XTP. I just ordered some Sierra 158 JSP also (precision reloading) actually has them in stock. We'll see who the winner is. I really like playing with new toys!

Holy moly . my Sierra data for 158 JSP for handgun is 17.3 gr W296 max load.. rifle data is 20.4 gr W296 max load @ 2100 FPS 1224 ft lb. I'll be sure to label "RIFLE ONLY" sorry all I'm just typing to myself !

Oops this is 125 gr data, for to many things going at once, step away from the loading bench and take a brake
