i use a mildot scope on both my hunter and standard rifles, but prefer a target dot, and turrets to dial in the distance just right.
adjust magnification so that dot covers or just covers the silhouette, then squeeze.
i'm running the mildot now as my rifles are doing "triple duty" (centerfire trainer, silhoutte shooters, and squirrel getters) and have tried the holdover / under technique last year. gets a little confusing here and there, but not impossible to do. just too much stuff to remeber for me while under the clock.
even on my 6-24x, i like to use 6x for chickens, 8x for pigs, 10x for turkey and 12x on rams. anything higher and my FOV gets alittle to narrow and i tend to lose what target i'm on in sequence, then have to go back to the beginning of the bank. basically i waste too much time searching for the correct target, but that's just me.
i'm sure the 10x will be ok, but i like the variable scopes on everything i have, it's nice to have the option if needed. but with the mildots, it'll be very rare if the dots will line up exactly at the different distances on a fixed power. at least with a variable and a second focal plane, you can adjust magnification to line the dots up just right.
anyhow, after that longwinded soapbox opinion, ultimately it comes down to the shooter and how well he or she feels comfortable and can utilize the equipment they got.
the buckmaster mentioned would probably be the better choice 4-14x or 6-18x, target turrets, target dot, side focus. it's alittle more $ than what you said your paying for the bushnell, but worth it.
there are a few scopes out there in the under than 200.00 range that'll work fine and have the "appropriate" options, it's just a matter of looking. i've had bad luck with the BSA line of "target" scopes, IMO i'd stay away from them.
