In my recent pursuit of improving my long range shooting I’ve made up some dope cards and figured up my trajectories for my hunting rifles. I’ve noticed that most ballistics calculators do not take into consideration the barrel length. Does barrel length make a big enough difference with trajectory to figure out how to take that into account?
I’ve also noticed that companies advertise superior bullet designs etc, but when punching in ballistic calculations between say federal terminal ascent 308 cal 175gr “fancy hunting bullets” and 308cal 175gr m118lr smk loads the trajectories are very, very similar. Is it worth making up dope cards for similar weighted bullets in the same caliber? These charts show similar performance... is real world performance similar? I’m looking at shooting sub 750yd ranges.
