Re: ballistic comp vs range cards
I say having both is the way to go. I shoot 1 load from my .260 and several loads in the 308 300 WM 243 and 7 STW. Fo rhunting I just use cards cause no battery no rain worries all that good stuff. BUt I use a comp for making those to get me started. Use field data over everything. Not saying it's the best but it works for me. JBM link on this site works well for free. Good luck
