>>1098815A Browning Cobra is a highly desirable vintage recurve, congrats anon. I have a Browning Wasp myself. They made some really good bows, perhaps under appreciated compared to the bigger names like Bear and Wing.
If you have 30' and a reliable backstop, you can always get some effective shooting practice done using half size targets. Just whatever you do, don't sell that Cobra! It it's too heavy for you, get a dinky Sage and work up to it. Vintage one-piece recurves are so nice to shoot.
