Thanks Bob.
    I use lead alloy with 1% tin. And I am very happy with the casting, as I have gotten a very low percentage of defective With successive modifications of my BT65 I have managed to move my bullets at good speeds to have a good turn of stretch marks. But the rifle (second hand) has not had a fault after another. And now I return to the tarbajo to find the best groups to different distances.

Fullpower: 100% hammer spring tension, with 51 g BT bullets

bullets 253/51 BT

My best groups I get them with the bullets of 41 g recalibrated to 253. I have tried 254 and 255 and there are no improvements of the groupings.
My bullets of 51 g bt enter the room a little hard, I think it was not well mechanized and it was somewhat short. The 41g-shorter ones are very soft.
