How many shots do you think you'll need?

Magazines and their capacities should only be issues for people who can't hit their target with the first shot. I've hunted deer and pronghorns for years with a single-shot Ruger No. 1. Follow-up shots have never been an issue, even with a "puny" .243.

Although I recognize there's a loyal following of the "brush buster" theory regarding calibers, I've used my .30-06 in some pretty thick stuff and if I've ever considered it a liability, it's more because of the barrel length (22") and the FOV of the optic (4-12x) than the caliber itself. I've never been a fan of "see-thru" rings. Just my opinion, but I feel if the brush is that thick it's better to opt for a lower-powered optic (I lean 1.5-5x) with a wider FOV - or straight iron sights - than something that'll let you use your iron sights, but which mounts your optic high enough over the bore that you can't obtain a proper cheek weld.

Lastly - and probably most importantly - which of the two rifles here do you shoot better? Use it.
