Platinum powerbelts!
Well, I got a chance to try out some platinum powerbelts, and I have to say I was favorable impressed with their accuracy. Time constraints only allowed me to fire 6 shots. I used 100 grains of ff 777 and 338 grain platinum powerbelts in an Omega (my brother's since I just sent mine in for work). I also use a peeprear sight and a fiberoptic front sight. At 25 yards, 2 shots were touching and 1 was about 3/4 inch away. At 100 yards my 3 shot group was just less than 4 inches. Pretty good for just picking out an arbitrary amout of powder. Need to try some more bullets and try some varying powder combinations, but that kind of accuracy right out of the box was pretty impressive.
The only question now is how they perform on game. If the accuracy holds up in more trials, I am going to consider using them on elk this fall. Supposedly, they are more aerodynamic and should hold their speed better, and because they have a smaller hollowpoint, they are supposed to have a better controlled expansion than the previous ones. May have to chrony some and see what kind of velocity I am getting. They also claim that the plastic ring comes off when it is supposed to, so I am going to be looking for the bases to see how far down range they get.
