Rifle scope mount input. Got some?

I need some input on what scope mounts to get for 3 rifles. Accelerator 17HMR with Nikon 3-9x40mm… /Remington 700 BDL 30-06 with Leupold VX-II 3-9x50mm… /Sub Moa.338 with Leupold VX-II 4-12x50mm. Anyone with any experience with these rifles or knows what their talking about I
appreciate the input. Not afraid to spend for reliability, but look for good bang for the buck.

I use Leupold mounts for centerfire rifles, and I like the dual dove tails that lock in place. You can get them in "High" mounts for the Rem and Weatherby for clearing the 50mm Ocular front. You could go with Weaver style, but I've always found the Leupold system to be rock solid.
The 22 isn't going to need to fight recoil, so you have more lee-way, and since the Accelerator has a Weaver style (near Picatinny looking) set-up Weaver rings will work great.

The answer to your question isn't a straight forward one. I think a lot of what will dictate what you need is riding on what type of applications you intend to use these rifles for. For example, a target rifle that is primarily going to live in a padded case until it gets to a firing range will do fine with aluminum rings and mounts, whereas a tactical rifle intended for hard field use or a hunting rifle that is going to be bouncing around in a Jeep or something off road would benefit from steel rings.

There's one general guideline that I can offer that will help you universally, regardless of the intended application. Choose whatever mount/ring combination that will allow you to get your scope's objective lens as close to the rifle's barrel as possible, but without actually touching it. This will help with accuracy…

Imagine an imaginary line from your muzzle to your target… This is known as "line of bore." Now imagine an imaginary line from your scope to your target… This is known as "line of sight."Obviously, when you sight in your rifle, you are setting a point at a given distance at which these two imaginary lines converge at a single point, and this inherently creates an angle between these two lines. The higher you mount your scope-(line of sight) above your rifle's barrel-(line of bore), the more extreme this angle becomes. As such, you shots taken either in front of or beyond your set zero range will deviate in error with a more extreme measure in correlation to how high above your bore line you mount your scope. It isn't as apparent at longer ranges, but a scope mounted high on a rifle will have a drastic impact shift when shooting at targets closer to the shooter than the set zero range.
