Thanks everyone! I didn't grow up in a hunting family, so I'm kinda making this all up as I go. I really appreciate the advice. Sounds like investing in a more quality scope would be the better way to go. I try to get out and shoot as much as I can with both rifles.
Does anyone have any experience with Maven optics? I've been looking at the CRS.2 4-16x44 SFP
OP, there's lots of great points that have been made here, but a couple I haven't seen yet:
1) One of the biggest reasons for the smaller caliber trend on here is not just reduced recoil, but the key benefits that come from it: generally more accurate shooting because of reduced flinch/recoil anticipation, and especially with .223, vastly cheaper ammo and, because of the minimal recoil and minimal cost, the ability to train far more regularly at much higher volumes of shooting.
2) If you really want to maximize your capabilities, maybe consider selling one of your .30 cals, and get a .223 in the same model as a trainer gun. As an added benefit, with good ammo the .223s are absolutely proven deer slayers, and there's a whole thread here with proof of grizzly, moose, elk, and walrus kills as well.
Regarding optics, the Maven RS 1.2 2.5-15 is very highly regarded here, because of the reticle options, its ruggedness (it passed the drop tests others mentioned), and given the price is one of the best values you could get as well. I can't speak to the other scope you mentioned.
