I am going to try those 150 HPBT's again, maybe I did something wrong, they did real good at 100 so at 200 they should have been no more than a 2" drop. No I do not have a headspace gauge, but I do check my overall length. Funny thing also, I had 1 round left of the 150 BT's so I shot it out of my model seven at 200 and was just left and about 1.5 in low of the bull, Go figure.
