Hi BB.
Sorry to hear about your rifle mate.
Before you go spending more money on a new barrel, have a go at straightening yours, it can be done.
First, remove the scope, and the stock from the rifle, trigger unit to if possible.
Lay the rifle mechanism on a table, use a towel for protection, and to help stop too much sliding.
Cock the rifle holding it as straight as you can, let the cocking lever go all the way untill it bottoms out, then apply further pressure, you will feel the barrel move, then it will offer resistance again, at this point you will know you have gone far enoug
