What scope has the highest secondary magnification? I think Im asking that right. Can be a 1x or 2x. Example: I have a primary arms 1x6. Does anyone make a 1x12 or 2x20?

I'm not getting what you're saying. Did you mean a Primary arms 1-6X24? Are you referring to variable magnification scopes? 

He's asking what LPV has the highest magnification while still maintaining a 1x or 2x on the low end.

OP, I'm not aware of any scope with a 1x or 1.5x that has anything more than 8x on the high magnification range.

There are 2-10x scopes out there. Burris makes one. I'm sure there are more though.

Many companies with a 1-8

Vortex Viper PST gen II has a 2-10

That's the highest I'm aware of in both flavors.

Think 2x10 would get me on a 10in plate at 350yds assuming im a decent shot?

A 1-4 or 1-6 would get you on a 10 inch plate at 350 yards if you are doing your part. The general rule is 100 yards per 1x for magnification. I usually buy scopes based off how far max I'll be shooting the rifle, or, how far out the round is still effective. For hunting I find I like a bit more zoom, close to 75 yards per 1x.

Easily. PST gen2 2-10x is definitely a good choice.
