Charlie,
I like the the Leupold Firedot recital in the VX-R or the VX-6. The VX-R in a 3-9 runs $499 and the VX-6 in 2-12 runs $1,199. They both come in different recital types, my favorite is the Duplex but you may like something different. The Trijicon 3-9 with the Crosshair Dot would be another fine choice, it sells for around $872. I have a lighted triangles on my crossbow and they work great but after so many years of competitive shooting I prefer a dot. The Leupolds use a battery, so that may be a concern but they have an automatic shut off to conserve battery life. So their you have it the Chevy, Buick and Cadillac of the lighted recital world. If you plan on using your 416 Ruger (man that's a big gun for a 150lb cat) you my want to research if heavier recoil effects the Firedot, I assume because every DG rifle you see on "Track Across Africa" has a Trijicon scope mounted to it they don't have any issues with recoil but you know what they say about assume.
Let me know when your heading to the range or Cabela's, I can always use more practice or more hunting gear.
