What is a better gun in general a Mosin Nagant or a Remington 700 .243?

In terms of quality, the remington 700 is a much finer rifle. On the other hand, the Mosin Nagant can be cheaper, possibly just as accurate, and have more stopping power. In my opinion(That does not mean it is the best), I would get a Mosin Nagant because I have this fear of my weapons not having enough stopping power. A Word of advise would be to clean the Mosin Nagant thoroughly after shooting and to remove any of that excess junk inside the chamber that makes for a tough bolt to open. All in all, they both have their faults and it is up to you to decide which you deem is required.

Stay Safe

Hope this helps.
