Just wanted to give an update and perhaps give you some hope.. I went to the range yesterday with some custom Berger ammo, 210 VLD in 300 RUM and got really god results. I had 4 groups of 5 with different loads, seating depths, etc and got really good results with one group, well under 1" MOA with 4 out of 5 shots. VERY happy as these bullets are really unique and there really isn't anything else that performs like them as far as a delayed expansion after penetration. The BC is also rediculously high at .063 and I am getting just over 3K FPS. Can't wait to try it out on some Mulies this year as well as Black Bear in Alaska in Sept if I can make it.
Anyway.. just wanted to let you know that while this bullet is difficult to load, and some rifles just do not like the secant ogive and long boat tail, it is possible and you can get good groups. I actually ordered mine from an ammo guy. Cost me 40 bucks for a sample pack. NOT BAD for custom made. sample ammo made is 4 different loads, powders, depths, etc. Here is the link if you are interested. His name is Alan and he is a pleasure to work with.
