I was about to jump on a Fullfield 2-8 for a lightweight scope for my newest 30-30 so hopefully someone has some positive things to say. My Burris experience overall has been pretty good.
I used to use FF 2-7 as prizes for shoots I put on in the ear 2000's, never had a complaint about them. I've only owned two Burris scopes since a Sig. Select and a 4X(Euro Scope) both have been good scopes.
Never used the 2.5-10 but have a number of the 4.5 -14x42 w/ballistic plex for years. Outstanding for predators; found the E1 reticle to be even better, especially as eyesight diminished. E1 is a much bolder reticle, great for old eyes.
