Some people apparently do have a hard time loading .17 cases, either with handling the little bullets, or chamfering problems inside the case mouth. All the .17 bullets I've seen are flat-base and after a friend collapsed several necks one day he sold his rifle. I can't recall collapsing any necks, and have loaded thousands of rounds--but I trim them in a Gracey tool that chamfers as it trims.
Will be interested to hear how the Midsouth hollow-points shoot in your rifle. I shoot plastic-tipped 20's on prairie dogs, having found they make a difference in both flat trajectory and explosiveness, but 20-grain hollow-points work fine for ground squirrels, as most are shot inside 200 yards. Have had great luck with Berger and Nosler Varmageddon 20-grain HP's but the Midsouth bullets are considerably cheaper.
