Just wondering if the magazine from a 10/22 and a 77/22 are the same mag?

Cheers.

NOTE: The Ruger 10/22 magazine (BX-1) will fit in the model 77/22 rifle, but the bottom section of the 10/22 magazine will not be
flush with the trigger guard assembly of the 77/22. The 9-shot 77/22 Magnum and .17 HMR magazine is not interchangeable with
any other magazine, nor is the 6-shot 77/22 Hornet magazine.

Above note copied from the 77/22 Parts list from Rugers website. The 77/22 magazine is JX-1, the 10/22 is BX-1. Hope this helps

Cheers Sam - much appreciated.
