I shoot .22LR, 5.56/.223 and I like to use splatter targets. Looks like a spotting scope is needed for clarity.
That's Great! If I get my way I just might end up with a Bino and a Spotting Scope!
With that smaller calibers, a bit more clarity to spot hits will help. Especially if you’re zeroing or shooting a bunch on a single target, you’ll want to see where the new hits are. If you’re shooting groups, say 3-5 shots on a given target then move, you can likely get away with a little less mag or clarity (objective).
I went from a 20-60x60 (maybe 65) to 85 and noticed quite a bit of difference. I did go to a higher quality glass though. Less mag with better clarity would’ve been ok for 100 yards at KHSC, but I also wanted a bit more mag for those occasions where I wanted to spot hits and misses for longer distances.
Another factor is size of spotting scope. For range use, but spotting scope is ok. But it is on the bigger and heavier side.
You will be able to spot hits at 100 yards with 10x binos, I’ve found that I need to stabilize on one of the columns to see individual hits.
