It's a 1 in 8 twist.
The 28" barrel was said in error. It is actually a 26" barrel. 26" from the bolt head to the crown NOT 28". I will edit my ad.
Good catch-Geedubya.
Just happen to be a Cooper-nut
IHMO, a pre-enjoyed Cooper such as the one you posted at the price you are asking is one of the best values out there.
BTT for a fine rifle.
Best,
