Mossberg 100ATR in .270 aftermarket barrel

Hello all,
This is my first post so forgive me if I'm posting something already asked. I just bought my first bolt action rifle and am looking to upgrade it in certain ways and am curious what a good aftermarket barrel. I'd like to start doing some long distance competition shooting. I know its not the best of the best rifle but I would like to make the best of what I have. Thanks in advance

I would look at Columbia River arms. They have prefits. Second good luck getting the barrel and action apart. It took a 12 ton press and action wrench with 3ft cheater bar. I’m in the process in converting a mvp 224 valkyrie to 6.8 spc. I got everything a part with help from a friend from work. I’m still waiting on the barrel. Their lead times are 8-12 weeks.

Thanks for the advice. If anything I would take it to a gunsmith for the work. I would like to make the most out of my rifle.
