Do a search for "Eagle View Research 5MM Craig" and you will get all the information you need. These guys are great to work with and have a ton of information. I have a 10" contender and my friend had his remington converted. Just starting to play with my t/c and getting 50yd 2inch groups while fireforming the brass and 30 gr bergers. Should be able to really play with it in the coming weeks using the fireformed stuff and then I'll chrony it and get serious with the accuracy. The bolt gun is getting 100yd 2inch groups with the fireformed stuff that he has reloaded. We're sharing the dies but keeping each others brass separate.... Anyway, I'll follow up as soon as I can to let you know.
I do have 40 rounds of original 5mm Rimfire avail if interested.
