That system works well, I put it on my kids 243 this fall and shot targets with it out 400. If you can get a chronograph or a magneto speed it will make setting up much easier. Of course, all the deer my kids shot with it were less than 100 yards, but my 10 year old did use it to nail a Javelina at 283 yards. Range it, hold for the red dot and boom. I picked mine up from Midway on a “blemished”sale last year for $315.
