What do you want to know? My advice for starters, is you get what you pay for. I've run Aimpoint COMP series and T1, Burris Fastfire 2, EoTech, Trijicon RMR and recently a Bushnell TRS25. I hear good things about the Bushnell on centrefire guns but I've only run it on my rimfire so can't comment for sure. The Burris is the next most economical(not cheap, economical) reddot. It holds up well and is very compact. The Aimpoint COMP series is bombproof but larger in size, more akin to flattop rifles like an AR(naturally, its the market they were designed for). The T1 is tops but comes at a price. Eotech is decent, although they're quite large, expensive, and there have been QC issues in the past 5 years or so. The RMR I run is the dual illuminated and its awersome. No issues and no batteries required...Ever. I ran a buddies RMR with the battery powered reddot and it was just as nice. My only gripe about it was the auto adjust illumination, which was a pain at times when you wanted to turn down the dot. The newer model is available with a manual adjustable dot. Trijicon is tops and it too comes at a price.
For your 305 or the 300win I would start with a Burris fastfire or a Trijicon RMR. If you wanted to risk it you could go with the TRS25($120 give or take) but I suspect the recoil may destroy it.
Average prices below. If you shop around you can find some deals.
T1- $500-700
COMP series $500-700
EoTech $500-700
Trijicon RMR $480-600
Burris Fastfire $350ish
Bushnell TRS25 $120ish
