New FTR shooter
I'm new to FTR and love it and have been learning all I can.
My mentor believes in heavy bullets, 175's for across the course shooting, as well as 1000 yds, as he states they buck the wind better than lighter weights.
Keeping one bullet weight on hand simplifies his loading, and of course he's got a load he's familiar, confident and experienced with, sure of his come ups.
Just the other day he commented that 190's were popular w/ some shooters to 600 yds as the are very wind resistant, but to slow at 1000 out of .308 to stay supersonic with the various combo's of powder and some bbl lengths, thus more vulnerable to wind at 1000 to suit him.
The appeal to me for 155's is that they are flatter shooting, ( I think he said by 6MOA or so) and can be driven fast enough to stay supersonic. In unknown distance shooting, as in the sniper/tactical steel matches, that could be a plus and make up for some range estimation errors.
I'd like to try that eventually, but I'm not ready yet.
