Littlemac,

You shooting a TC? They didn't shoot out of my Black Diamond either. The bullet is supposed to be undersized and the plastic oversized to contact the rifling, this is why they are so easy to load. My opinion is thay TC's have shollow riflings and don't work well with the undersized bullet. Below is the thread I posted after I tried them, it explains what happened with me. I received several replies from guys shooting TC's that had the same problems. Most of the replies I recieved from guys that were shooting in a TC had to greatly reduce their powder charge/velocity to get them shooting well.

Went to the range today to test fire some 295gr HP Power Belts and it didn't go so well. I had to leave scratching my head with confusion. I am shooting a TC BD topped with a Weaver V10 2x10x38. Keep in mind that I have made several recent trips to the range shooting my regular loads of 240gr XTP, Mag express Sabots over two 50gr Pyrodex pellets (lighting it with 209's) and had been getting consistent 1" - 1 1/2" groups at 100yd.

For my test with the Power Belts I kept my load the same, as mentioned above. I started off by finding my zero at 50yd. (2 shots), I was 1" high. Next I moved to 100yd and the first shot was no where to be found. I shot again and found it about 8" to the right. I went back to 50yd and shot about 5" to the right. Again at 50yd, I dialed the scope over and shot dead on again. Back at 100yd my next shot was on line but low, followed by one more shot about 4" to the left. I immediately wrote it off as a scope failure, however, I couldn't help but notice the bullet holes at 50yd were enormous and somewhat oblonged left/right, yet the 100yd holes were tight and round. The only thing left to try was to shoot my regular saboted XTP load for comparison. At this time I only had enough pellets for 5 more shots. At 100yd it took three of those shots to get my back near zero. Note, I made scope adjustments between each of those three shots and the scope tracked perfectly to the adjustments. The final two shots were side by side, less than ½ apart perfectly at my 1" high zero.

I don't know how accurate this is or if it means anything but I checked my scope adjustments with the use of my boresight. First, I made sure the crosshairs were even moving with the adjustments, they were. Second, I made sure that the click adjustments were consistent by adjusting several clicks one direction and then making sure the same number of clicks in the other direction would return the crosshairs to there original position, they did. Third I tapped the turret adjustment knobs with the but of a screwdriver to see if the crosshairs would shift from the impact, they didn't.

What do you guys think could be going on? Is it the scope or the new bullets? I am buying more supplies tomorrow and heading back to the range one more time before I start swapping scopes.

With all that said it was the bullet. I switched my load and went right back to consistent 1" - 1 1/2" groups @ 100.
