Spotting scope advice needed

My brother and I have recently joined a 300yd rifle range. Having mostly shot pistols we are unsure what kind of spotting scope would be best. A 16x rifle scope can see holes at 100yd but not really at 300. We're shooting a mix of calibers from .22 to .308 so far.

Would something like this work?

I'd rather not blow a TON on one.

thanks!

I bought a similarly cheap spotting scope at a gun show in Tulsa a couple of years ago. Seemed OK at the time. It is now gathering dust because it is a piece of crap. Was at the range the other day and a guy had an expensive rig set up on a free standing 5' tripod. It was amazingly clear...a Leupold I think. I know, I know, I don't want to spend the money either, but cheap crap is cheap crap. Don't waste your money.

Haven't tried it a 100 yards but I bought a Barska 20x60 with a 60mm objective lens for under $150 and it seems to be a good scope. Sometime in the near future I'll try reading the licence plates off of parked cars on the next street over that has an empty lot between that's at least 100+ yards across.

this is what i have and have been very happy with it. the tripod isn't that great but works from fine from a bench, and you're paying for good glass anyway.

The Barskas I've looked through, I wasn't very impressed with. Konus scopes, on the other hand seem to be up to the job of spotting shots at 100-200 yds. Beyond 200 yds mirage and light do more to determine whether you can see .22 cal bullet holes in the black even with a very good scope.
If you are going to shoot from position (prone, sitting and offhand) you really should save up your money for an angled eyepiece and those will cost you more than an equal quality in-line. Then you'll need a scope stand. Off a bench, a straight scope on a little tripod works fine.
Magnification isn't nearly as important as clarity and remember that you'll need about 1" eye relief so you don't have to remove your glasses to see through the scope.

I would stay away from variable power unless you go fairly high end, 15-20 power with 50-60mm objective if the glass is clear will do a good job.
When you are shopping and comparing look at small dots similar to bullet holes, any scope will make big things bigger but bullet holes and judging antlers and horns from afar are a different story.
I have two old Leopold's, 20X50, 20X60 and a Redfield with adjustable angle that had both a 15-40 variable?? and a straight 25 lens. I pulled the variable because it made a good scope junk.
Now aside from the Leupold 60mm being a little brighter than the others I have 3 scopes that stand up well to some that cost 5-10 times what I have in these.
They are not Swarovski's but they are close enough that guys who have Swarovski scopes kind of cringe when they look through them knowing what I paid.

I have a Barska 20-60x. It is 'acceptable' for spotting. I can make out .17HMR holes at 100 yards.

I have a konus telescope that I am quite pleased with. If I recall correctly they are actually a Spanish company (most optics are coming out of china now). Konus usually hits a good sweetspot between price and quality, at least with optics. From my experience.
