Went to the range today with my Crockett. The picture attached is what I worked up. Seems to like 15 gr of 2 f. With 20 gr my shot group opened up a little more. The first 3 shots were low. I changes my sight picture and the next 3 were better. After these I shot maybe 20 more at different targets and it shoots a lot better than I can. I do have one question. I would like to go back to my original sight picture. To raise a shot group in fixed sights do I file down the front sights? For the life of me I can't wrap my head around adjusting the sights so I adjusted my sight picture.
