I've shot CCI w/ TNTs, Winchester Supreme w/ a tipped bullet, Federal tipped and Hornady tipped. The all pretty much shot the same except for the CCI TNTs which for whatever reason don't shoot as tight as the tipped bullets. But then again, I've never been able to get most Speer bullets to shoot well.

I believe all .17 HMR is loaded with Lil Gun which made the .17HMR possible. All the loads are either loaded with TNTs or V-max and tend to hit the same POI once zeroed with the TNTs opening the group a bit.
