Hi, new member, first post.
To the OP..... don't do it!
I'm in a similar boat, in that I have a cz455 thumbhole in 17hmr and I had (til last Thursday) a T bolt synthetic in .22lr,
I had the 22 first and thought it was ok, the action is nice, but it is so light and dainty, far too light IMO, for a 6ft burly farmer anyway, I couldn't hold the thing steady for love nor money!
Then the cz 17 came up for sale from a friend of a friend, I probably wouldn't have gone the extra ££ if buying new from a RFD for a thumbhole stock and heavyweight barrel, but I love it, the only time the weight has been a issue has been lamping, trying to carry round sticks and gun kitted out with lamp.
The cz handles and shoulders so nicely compared to the T bolt and the safety works in the opposite way which was really the final nail for the T bolt.
So its gone back to be replaced with a cz452 synthetic when the variation is done.
If the op is set on a T Bolt, look at the wood stock sporter or the varimant heavy barrel, which isn't actually too heavy either.
