I took the B&C stock off my 6.5 and took it and two factory stocks to a local UPS store and had them weighed. Here are the results:
Tikka T3 factory wood stock: 28 oz.
Tikka T3 factory synthetic: 28 oz.
B&C Medalist stock: 35 oz.
Thanks for taking the time, and giving us a report. I'm surprised the factory wood weighs the same as the synthetic!
