I have been fortunate enough to use them for the past 10 years. They are new to the people who don't know about them, but they are not new to the shooting world. The best shooting Voodoo rifles have always had them. I have used them on my own F-Class and PRS/NRL rifles. I have also threaded/chambered more than 40 of them and have not had problems with a single one yet. They are absolutely top quality and perform amazing. If you have a need for a special twist rate, talk with them and you will probably get exactly what you need. For example, my F-Class barrel has a 1:11.7 twist rate. A couple weeks ago I chambered myself a 22 Creedmoor for coyote hunting. Below are some of the results. The larger of the 2 three shot groups are shots 11, 12 and 13 out of the barrel. The 6" steel plate was shot with my thermal scope (HALO-XRF) at 338 yards. I absolutely recommend them!!
