Sholling, are you saying that the Monarch 2.5 x 10x42 is to much scope for it?
Not at all. I'm Saying that the fixed focus Monarch 2.5-10x42 rifle scope is optimized for a centerfire rifle. That means that it's set to be parallax free at 100yds (see below
). A scope designed for a rimfire will be set to be parallax free at 50yds (60yds for a Leupold). Because parallax errors tend to show up more at short range you're more likely to have noticable point of impact issues at 50yds with a scope set for 100yds - than you will at 100yds with a scope set for 50. The best way to understand parallax and parallax correction is to read this explanation
Most of the time people aiming a centerfire rifle through a hunting scope like that Monarch are shooting at medium to large critters at 50-250yds and parallax won't be an issue at those ranges with a critter with an 3-4" kill zone. If you're 1/2" off at 50yds because of a parallax error it's no big deal.
Those shooting rimfires are generally shooting at a really small target or critter at 25-100yds, call it 50-60yds on average and maybe with a 22mag reaching out to 150yds once in a great while. Remember that little tiny bullet is being blown all over the place by any kind of breeze. EDITED
To answer you're question of fixed-focus rimfire vs a fixed-focus centerfire scope - only you know what ranges you'll be shooting at. Read up on parallax and decide if it's going to be an issue for your planned usage. Just to clarify if you were a precision target shooter you would probably be using scope that allows you to adjust out parallax errors at any range. But that slows the shot too much for most hunters. The 3-9x Weaver RV9 and Leupold Rimfire E.F.R. allow you to adjust out parallax at any range. So would a higher magnification centerfire scope like a Bushnell 4200 4-16x40. Again it comes down to how you plan to use it.
