Greetings-I’m new to the Hide and long range shooting so I’m looking for some credible advice. I just ordered a Vortex Viper PST 6-24x50 to put on my newly acquired Browning Left hand Grey laminate Long Range 6.5 Creed. Would you recommend I use a Picatinny Rail for the base set? And if so, do I go with the 20? I typically will only be shooting 300-600 yards so maybe it’s not needed at these “short” distances, but want to have the option if I can find a range to shoot longer. Your time and thoughts on this are appreciated.
