Take it
If I remember correctly the Remington has a 1-9 twist which will stabilize the long and heavy 105gr. A-Max bullets. I have one in a BDL varmint and really like it. As mentioned before you can pickup bullets for them cheap at gun shows as not many people show much interest. I think I have something like 15-20 boxes of bullets at present.
Mild recoil, accurate, easy to load and readily available components are the best attributes of the 243.
