I have the hunter in .243. Love that little rifle! Super comfortable, super light, well balanced and very accurate with a variety of ammo. However, the clip and clip insertion is my least favorite thing about that rifle. Yes you have to slide the shells in like you described but the thing I dislike worse is when I put the clip in I have to tilt the rear of the clip in first then push the front in to get it to click into place. It’s really plasticky stiff too which may or may not get better over time. When I first took it out to shoot I had a hard time jacking in a shell, but that issue has aleaviated itself after 10-15 rounds. I don’t remember getting a proof of accuracy target either, which doesn’t matter now because I know what it’s capable of. Have fun with your 6.5, if it’s anything like my .243 you’ll love it.
