I have a browning bar with boss in 270. I printed the boss settings off the net and they only mention 3 different grains and 2 brands. Federal 130 and 150 and remington in 140. I will set my gun to the 130 grain setting. So my question is: Can I use any brand bullet in a 130 grain and go by these settings. I know the rifle will shoot diff with diff grain but does brand matter. I have some federal 130's on order but I won't get them till monday so can I buy winchester 130's for the time being?
Thanks a lot.[]
