Thanks. Put a Simmons 3 x 9 x 40 on last night. One that I had laying around, but should be ok for the rimfire. Medium Leupold rings just clear the hammer spur, but clearance is clearance. Took the hammer extension off my 25-06 and ordered a new one from H&R yesterday. Looking forward to tomorrow afternoon. When I have a bad day, it is normally my fault, not the gun's.
