So my daughter-in-law's sister decided she wanted to purchase a firearm for home defense. She went to Wally World and bought a bolt action rifle in 243 Rem. I just found out about this the other night when I saw her. I am not familiar with this chambering but I hear it is pretty common and would be good for a small woman. (She didn't even know the brand of the rifle or the scope) I wouldn't have recommended this. A 20 ga. shotty would have been my choice but too late now. I will have to take her to the range, sight it in and give her some lessons. Not looking forward to it. So, any comments on the 243?
