G,day from Down Under
I have a Marlin Cowboy, 24" barrel and would like to see if it is possible to knock down the 500 meter Rams as used in Metallic Rifle Silhouette. But I want to do it without crossing the transsonic speed range. I want to stay sub sonic.I want to try and do it at about 1050 ft/sec. If I can launch this 310 or so pill at about this velocity, and actually hit the Ram, the momentum calculations say that there is a good chance it will go down. But I dont know whether the twist of the Marlin Cowboy is suitable for this. Also is there a suitable vernier type sight that will work with this. Thank you for any advice you can give.
cheers
