ok guys i have a question, i let a friend of mine use my remington 270 which got dropped and missed up the scope, dont have the money to buy a new one and neither does he. so my question is i have a bushnell doa 250 on my wolf black powder 50 cal. could i use that scope on my 270. if so do i need to sight it in the same way i did before at 100 yds. then use it the same way out to 300 yds. i know its for black powder but dont know if it will work on a center fire. thanks.
