Any reticle that has MOA or Mil hashes will work, it's just a matter of shooting it enough to know your holdover.Good advice, Im sure that has to do with the objective lens size as well.
i get a nice discount on the vortex scopes. I’ll have to look to see if their higher quality scopes have a bdc
BUT I'm also a big proponent of the mpb zero. In my 350L, which has similar ballistics to a 450BM, and a similar max effective range of 200ish yards; has a mpb zero of 25 & 172 yards with a +/- 3 inches out to 200 yards. So i don't even need a ballistic hold over until past 200 yards.
